You can now meet the unique needs of educational institutions by privately offering apps you’ve customized just for them.

Organizations that you identify in App Store Connect will see the app and be able to purchase it in volume on Apple School Manager, a service that lets educational institutions buy content, configure automatic device enrollment, and create accounts for students and staff.

Educational institutions can also use this feature to distribute proprietary apps for internal use.

You can choose to create a new app for these platforms using a single app record in App Store Connect or add platforms to your existing app record.

In addition, App Store categories will be unified across the App Store and Mac App Store to align with this change, and to help make your apps more discoverable.

The “Photography” and “Video” categories on the Mac App Store will be combined into “Photo & Video”.

Mac apps and pending updates with the “Photography” or “Video” category selected in App Store Connect will be moved automatically to the combined category.

“Kids” will no longer be a subcategory within “Games” on the Mac App Store.

We’re pleased to announce that Apple Developer Program membership is now available at no cost for eligible organizations based in Australia, Canada, France, Germany, Israel, Italy, Mexico, and South Korea. Nonprofit organizations, accredited educational institutions, and government entities that plan to distribute only free apps on the App Store can request to have their annual membership fee waived.Learn about membership fee waivers

The App Store Review Guidelines are designed to help developers create apps that are secure, high-quality, reliable, and that respect user privacy.

In order to ensure this, we’ve always specified that all apps be self-contained bundles.

This means that the core features and functionality of the app must be contained within the software’s binary, rather than made possible by referring users outside of the approved app — including through the use of HTML5.

Apps that dynamically provide core features and functionality with web technology like HTML5 are best delivered through Safari, rather than through the curated App Store.

As a reminder, existing apps must be in full compliance with th…

When parents visit the Kids category on the App Store, they expect that the apps they find are suitable for children.

That’s why apps published on the App Store must protect children’s data and provide only age-appropriate content.

Apps must also require a parental gate in order to link out of the app, request permissions, or present purchasing opportunities.

It’s critical that apps do not transmit personally identifiable information or device information to third parties, and that advertisements are human-reviewed for age appropriateness in order to be displayed.

As a reminder, existing apps in the Kids category on the App Store must be in full compliance with the updated guideline 1…

When taxes or foreign exchange rates change, we sometimes need to update prices on the App Store.

Thailand: Prices will decrease due to changes in foreign exchange rates.

Pakistan: Prices will increase due to changes in foreign exchange rates.

Developers based in Singapore who provide their GST number in App Store Connect will not have their proceeds affected.

Prices on the App Store won’t change based on the introduction of this tax.

Apps should look great on all models of iPhone and iPad, regardless of display size or aspect ratio.

With features like Xcode storyboards and Auto Layout, your app’s interface elements and layouts automatically fit the display.

Support for Multitasking on iPad is strongly encouraged.

Adding support for multiple windows, and adopting Multitasking capabilities, including Slide Over, Split View, and Picture in Picture, will ensure your app delivers a modern and complete experience on iPadOS.

In September, we temporarily adjusted the notarization prerequisites to make this transition easier and to protect users on macOS Catalina who continue to use older versions of software.

Starting February 3, 2020, all submitted software must meet the original notarization prerequisites.

If you haven’t yet done so, upload your software to the notary service and review the developer log for warnings.

These warnings will become errors starting February 3 and must be fixed in order to have your software notarized.

Software notarized before February 3 will continue to run by default on macOS Catalina.

If your app still embeds web content using the deprecated UIWebView API, we strongly encourage you to update to WKWebView as soon as possible for improved security and reliability.

WKWebView ensures that compromised web content doesn’t affect the rest of an app by limiting web processing to the app’s web view.

And it’s supported in iOS and macOS, and by Mac Catalyst.

The App Store will no longer accept new apps using UIWebView as of April 2020 and app updates using UIWebView as of December 2020.

As part of Apple’s commitment to security, we reward researchers who share critical issues with us through the Apple Security Bounty.

You can now earn up to $1,500,000 and report issues on iOS, iPadOS, macOS, tvOS, watchOS, and iCloud.

In addition, Apple offers public recognition for those who submit valid reports and will match donations of the bounty payment to qualifying charities.

Apple is taking a major step in its approach to the smart home by joining a new industry effort with Amazon, Google, Zigbee Alliance, and others.

The initiative aims to develop an open standard that will increase the compatibility of smart home products across multiple platforms, with security and privacy as fundamental design tenets.

The new standard will make it even simpler for developers to build one device that is compatible with smart home services and voice assistants, while ensuring consumers can easily choose smart home products that seamlessly work together.

Standard Library Preview Package February 18, 2020 Nate Cook is a member of the Swift standard library team at Apple.

I’m excited to announce a new open-source package and an enhancement to the Swift Evolution process: the Standard Library Preview package!

Note: The Standard Library Preview package itself is a product of the Swift Evolution process!

Using the Preview PackageTo use the Standard Library Preview package in a Swift Package Manager project, add it to your Package.swift file as a package dependency and a target dependency:let package = Package ( name : "MyPackage" , dependencies : [ .

Library Evolution in Swift February 13, 2020 Slava Pestov is a member of the Swift compiler team at Apple.

When to enable library evolution supportLibrary evolution support is turned off by default.

Furthermore, enabling library evolution support for a framework is itself a binary-incompatible change, since frameworks built without library evolution do not provide any binary compatibility guarantees.

More details about frozen structs can be found in a Swift evolution proposal, SE-0260 Library evolution for stable ABIs.

The main difference between using a framework built with library evolution support over one without is that with library evolution support, the compiler is more conservative …

I’m thrilled to announce a new open-source project for the Swift ecosystem, Swift Crypto.

Swift Crypto is a new Swift package that brings the fantastic APIs of Apple CryptoKit to the wider Swift community.

In order to make it easier for developers to update Swift Crypto when they are using it on non-Apple platforms, we took advantage of the Swift Package Manager to distribute Swift Crypto.

However, as Swift Crypto is an open source project, there is some scope for proposing API directly to Swift Crypto.

If you have questions or would like to discuss Swift Crypto, please feel free to chat on the Swift forums.

Swift Numerics November 7, 2019 Steve Canon is a member of Apple’s Swift Standard Library team.

I’m excited to announce a new open-source project for the Swift ecosystem, Swift Numerics!

Swift Numerics will provide the building blocks of numerical computing in Swift, as a set of fine-grained modules bundled together into a single Swift package.

I expect that once the Swift Numerics module has some use and we do a few iterations of building out its features, we’ll propose part of it for inclusion in the Swift Standard Library as well.

All of these projects (and others) are tracked on the issues page for Swift Numerics.

SSWG Annual Update October 31, 2019 Tanner Nelson is member of the Swift Server Work Group and creator of the Vapor web framework.

The Swift Server Work Group (SSWG) set out 12 months ago to begin defining and prioritizing new efforts to address the needs of the Swift server community.

The SSWG is working continuously to improve the Incubation Process and its recommendations.

Once a package has completed the incubation process and been accepted by the SSWG, it will be listed on the Swift server package index.

ToolingBeyond package incubation, the SSWG is also focused on improving Swift and its tooling on Linux.

New Diagnostic Architecture Overview October 17, 2019Diagnostics play a very important role in a programming language experience.

The types described in constraints can be any type in the Swift type system, including tuple types, function types, enum/struct/class types, protocol types, and generic types.

Type variables can be used in place of any other type, e.g., a tuple type ($Foo, Int) involving the type variable $Foo .

Constraints$Str String Argument str has a fixed String type.

$Plus disjunction((String, String) -> String, (Int, Int) -> Int, ...) Operator + forms a disjoint set of choices, where each element represents the type of an individual overload.

UTF-8 String March 20, 2019Swift 5 switches the preferred encoding of strings from UTF-16 to UTF-8 while preserving efficient Objective-C-interoperability.

Even forming a Swift 4.2 string from UTF-8 content involves transcoding the content to UTF-16, which can be expensive.

However, on modern processors and with Swift’s performance model, these advantages are overshadowed by the advantages of a single UTF-8 storage representation (see Unified Storage Representation below).

Since Swift 5 switched to UTF-8, small strings now support up to 15 UTF-8 code units in length without any significant downsides.

The breadcrumbs store an Array of string indices and the length of the string in UTF-16 cod…

Behind the Proposal — SE-0200 Enhancing String Literals Delimiters to Support Raw Text February 20, 2019The development, refinement, and deployment of SE-0200 Enhancing String Literals Delimiters to Support Raw Text was a long and surprising journey.

This feature allows variations of the delimiter to be included within the string, allowing more expressive raw string content.

Instead of creating raw strings, SE-0200 introduced something similar: a blend of the alternate delimiters Swift first encountered in multi-line strings and the customizable delimiters from Rust.

They support the same features you find in raw strings, they mostly act like raw strings, however the design incorporates esc…

Evolving Swift On Apple Platforms After ABI Stability February 11, 2019With the release of Swift 5.0, Swift is now ABI stable and is delivered as a core component of macOS, iOS, tvOS, and watchOS.

Apple will be able to deliver platform frameworks using Swift in future OSes.

These apps will continue to run using their bundled Swift runtime, since these older Swift runtimes are not compatible with the stable Swift ABI.

The Swift runtime in the OS is designed to be mutually ignorant of any bundled Swift runtimes, so it will see classes defined by the app’s bundled Swift runtime as plain Objective-C classes, and the bundled Swift runtime will likewise see Swift classes from the OS as plain Obje…

ABI Stability and More February 7, 2019It has been a longstanding goal to stabilize Swift’s ABI on macOS, iOS, watchOS, and tvOS.

ABI stability is implemented for each operating system that it compiles and runs on.

As development of Swift on Linux, Windows, and other platforms matures, the Swift Core Team will evaluate stabilizing the ABI on those platforms.

I am new to Xcode and Swift development and originally did game development in Unity for years. I decided to switch to Xcode from Unity because there just aren't any jobs in my area looking for Unity developers and figured I would have a better chance making iOS apps for companies instead. But while I want to make apps for clients I still want to make relatively big/detailed games in Xcode like I did in Unity. I want to work entirely in one IDE, that way I can master one code rather than juggle a few and just be decent at them. I have seen posts of people doing so in Xcode to make apps for work and games as a hobby. What I cannot seem to figure out is if you can make games that are as high …

I posted a question about my app, which runs a timer. The app wasn't running in the background, to which I received a helpful response about background modes. Once I setup the background modes, the app ran fine in the Simulator. My timer counts, and sounds of a Ping at right intervals. However, when I run the same app on my Device, the Timer hangs until it is back in the foreground, when it starts where it left off. Is there an easy way to solve this or is the local scheduled notifications the only way to achieve this? My only concern with local scheduled notification is that, I may have to schedule multiple notifications(upto 30) submitted by /u/hindustani_india [link] [comments]

However, considering we spend a great deal of our lives working, I want to make sure I absolutely love my line of work and truth be told after dabbling with iOS development I enjoy it a whole lot more than Web Front End development. Considering I have no degree except 2.5 years of college, would I be able to land a good paying job like I did with Web Development or does iOS development have different requirements in terms of education? I know in Data Science it is way harder as that sector is very academic in terms of maths and statistics but I want to pick your brain regarding career path…

Yes, Apple deprecated UIWebView and WebView with iOS 12, but I didn't think they'd be banned from the App Store this quickly.

Transitioning to WKWebView is rarely straightforward, mainly because it runs out of process, but also because the API is so different.

It's unlikely that you're using it in a new app, so this is all about the December deadline to make sure it's gone from all existing apps too.

I won't be surprised at all if we see an extension to this deadline (official, or otherwise) as we get closer to the end of the year.

Apple are listening but get moving because it's likely any changes will need to be locked in well before WWDC this year.

Iger said he would be able to help transition Chapek into the role while serving as executive chairman.

Tesla, and even Apple, are receiving some harsh criticism from the NTSB regarding a fatal crash on Autopilot in 2018.

At the time, Tesla CEO Elon Musk hit back at NTSB’s critique of Tesla releasing data of the fatal Autopilot accident.

During the hearing today, NTSB chairman Robert Sumwalt put some of the blame on both Tesla and Apple, the employer of the driver.

Sumwalt said about Apple:The crash driver’s employer, Apple, is a tech leader, but like most employers, has yet to develop a distracted driving policy.

Again, it sounds like NTSB is involving Apple here as an employer, not as the manufacturer of the phone involved.

Apple has updated its Research app for iPhone and Apple Watch with a few notable additions today.

The Federal Trade Commission has announced today that it has started sending $1.7 million in refunds to customers who fell victim to a tech support scheme.

According to the FTC, the perpetrators of the scam tricked people by claiming to be representatives of large tech companies such as Apple.

In a press release this afternoon, the FTC explained that it will provide 57,960 refunds averaging about $30 each to victims of the scheme.

Apple Watch Activity Challenges are continuing with the next challenge set to kick off on March 8th.

The challenge is meant to encourage Apple Watch customers to be more active while honoring International Women’s Day.

The rules for the upcoming Apple Watch Activity Challenge simply require users to complete a 20 minute walk, run, or wheelchair workout on March 8th.

Apple Watch customers will be notified about the upcoming challenge on their devices ahead of time.

This marks the third annual Activity Challenge for Women’s Day since Apple started honoring the day with the Apple Watch feature in 2018.

At the event, the company announced its 3rd-gen 5G X60 modem with the capacity for super-fast download and upload speeds.

Qualcomm is testing the X60 with partners this quarter and it’s possible the iPhone 12 lineup could feature the new chips.

Today at Qualcomm’s “What’s Next in 5G” CEO Steve Mollenkopf described 5G as “the beginning of a multi-decade opportunity.”The first major announcement is Qualcomm’s new X60 5G chip.

Qualcomm also highlighted that this is the first 5G chip to aggregate mmWave and all sub-6GHz spectrum, including 4G bands.

While Qualcomm’s specs for greater than 7 Gbps speeds with the X60 5G modem are exciting, real world use will certainly be at much lower speeds as …

Apple tries to improve iPad’s multitasking capabilities every year, making the system more powerful to perform multiple tasks simultaneously.

But this has also raised questions about the usability of multitasking on the iPad, which has become increasingly complicated for some users.

Now, if you open an app, you can only use it in Split View with another app that’s showing up in the Dock.

One of these people is designer student Tommy, who created a concept to show how Apple could improve the multitasking experience on the iPad.

In the concept, each app in Split View can be controlled by the home indicator, so you can close and change only one of them.

As a major…

Let’s see if we can make the above code more type safe, and in doing that, make it feel more “Swifty” as well.

recent ]That’s perhaps the essence of what makes code “Swifty” in terms of type safety.

resource = resource if let preloadable = resource as ?

What’s important to note is that writing “Swifty” code from a safety perspective is definitely not about using generics as much as possible.

By making our code use Swift’s type system both to ensure correctness and to make its functionality more clear, by fully utilizing the standard library, and by conveying the intent of our code through expressive naming and API design — we often end up with code that better matches …

However, sometimes we might want to base a ForEach on a collection of simpler, raw values — such as strings.

self ) { tag in Text (tag) .

cornerRadius ( 5 ) } } } }Another option would of course be to wrap our raw values using an Identifiable type, for example like this:struct Tag: Identifiable { var id: String { name } var name: String } struct TagList: View { var tags: [ Tag ] var body: some View { HStack { ForEach (tags) { tag in Text (tag.

Element , Content : View { init (values: Data , content: @escaping ( Data .

self , content: content) } }Note how we use an external parameter label above, which the built-in ForEach APIs don’t.

Sometimes we might want one of our SwiftUI views to only be constructed and shown in case a certain optional value is available.

For example, here’s how we could make our ProfileView accept an optional User , rather than a concrete value:struct ProfileView: View { var user: User ?

private let contentProvider: ( Value ) -> Content init ( _ value: Value ?, @ViewBuilder content: @escaping ( Value ) -> Content ) { self .

value = value self .

For example, we could now easily construct an entire optional view hierarchy like this:struct HomeView: View { @ObservedObject var loginManager: LoginManager var body: some View { VStack { Unwrap (loginManager.

One of the key ways that SwiftUI is different compared to Apple’s previous UI frameworks is how its views are created and configured.

However, SwiftUI also supports indirect configuration, as many different modifiers and properties are automatically propagated down through each given view hierarchy.

For instance, let’s say that we’re building a view for displaying an address within an app, which consists of a series of stacked Text views:struct AddressView: View { var address: Address var body: some View { VStack (alignment: .

Apart from writing View extensions, SwiftUI also enables us to define custom view modifiers as types conforming to the ViewModifier protocol.

Just like its pred…

Here’s how we might refactor the above function to use that pattern instead:func setupApp(forUser user: User ?)

viewDidLoad () let headerView = HeaderView () view.

headerView = headerView let logOutButton = UIButton () view.

addSubview (logOutButton) ... } func userDidUpdate( _ user: User ) { headerView.

{ URL (string: string).

Even though Swift isn’t a strictly functional programming language, there’s no doubt that functions play a very central role in its overall design and usage.

From how closures are used as asynchronous callbacks, to how collections make heavy use of classic functional patterns like map and reduce — functions are everywhere.

What’s interesting about Swift 5.2 in this regard is that it starts to blur the lines between functions and types.

ID { func callAsFunction( _ value: Value ) { insert (value, forKey: value.

raw (value) } } func chained(to next: @escaping ( Output ) -> T ) -> Function < Input , T > { Function < Input , T > { next ( self .

New in Swift 5.2: Key path literals can now be passed as functions.

This might be a small change in the grand scheme of things, but it really makes closures in which we’re simply accessing a property read so much nicer — since we can now pass that property’s key path directly:struct Movie { var name: String var isFavorite: Bool ... } let movies: [ Movie ] = loadMovies () let movieNames = movies.

name ) let favoriteMovies = movies.

isFavorite )

append (article) guard results.

append (article) guard results.

For example, here we’re adding a new view for each of an array’s elements, which can be done really elegantly using forEach :func addArticleViews(for articles: [ Article ]) { articles.

forEach { article in let articleView = ArticleView () ... view.

forEach (addArticleView) } private func addArticleView(for article: Article ) { let articleView = ArticleView () ... view.

Let’s take a look at how we can utilize Swift’s various collection slicing APIs, and how doing so can help us boost the performance of various algorithms and functionality.

Whenever we’re defining an escaping closure — that is, a closure that either gets stored in a property, or captured by another escaping closure — it’ll implicitly capture any objects, values and functions that are referenced within it.

user = user storage.

id ) { [ weak self ] user in self ?.

message message.

id ) { [ weak self ] user in assert( self != nil , """ It seems like UserModelController didn't unregister \ itself as a storage observer before being deallocated """ ) self ?.

The Swift standard library’s Result type might just be a simple enum with cases for modeling an operation’s success or failure , but it also comes with several really useful convenience APIs built-in.

For example, it has a closure-based initializer, which we can use to easily convert any expression that throws into a Result value:let data: Data = ... let decoder = JSONDecoder () let result = Result { try decoder.

decode ( Model .

get () let decoder = JSONDecoder () return try decoder.

decode ( Model .

Besides that, the only real requirement is that each property wrapper type should contain a stored property called wrappedValue , which tells Swift which underlying value that’s being wrapped.

For example, let’s say that we wanted to create a property wrapper that automatically capitalizes all String values that were assigned to it.

That might be implemented like this:@propertyWrapper struct Capitalized { var wrappedValue: String { didSet { wrappedValue = wrappedValue.

wrappedValue = wrappedValue.

flag = flag super .

A test assertion’s main role is to compare a certain result against a control value, and to fail the current test if those two values don’t match.

add (item) let retrievedItem = collection.

add ) XCTAssertEqual (manager.

remove (notes) XCTAssertEqual (manager.

insert ( let index, let element, let association): if let oldIndex = association { return """ Element moved from index \(oldIndex) to \(index) : \(element) """ } else { return "Additional element at index \(index) : \(element) " } case .

When we define any new type, property, or function in Swift, it’ll have the internal access level by default.

Here’s how we might use that to implement a DiscountedPriceCalculator , which lets us apply a given discount to all price calculations:class DiscountedPriceCalculator: PriceCalculator { let discount: Int init (discount: Int ) { self .

discount = discount super .

discount = discount super .

Any type, property or method that’s marked as private will only be visible within its own type (which also includes extensions on that type defined within the same file).

Swift includes a number of features that can help us make our code more concise and easier to read, such as its type inference capabilities, type aliases, and the way that types can be referred to within their own declarations and extensions.

For example, let’s say that we wanted to extend a generic type, such as the PublishingStep type from Publish, with a new static factory method.

When declaring our method, we could of course type out PublishingStep every time that we want to refer to the extended type itself, like this:extension PublishingStep { static func group( _ steps: [ PublishingStep < Site >] ) -> PublishingStep < Site > { PublishingStep < Site >(...) } }However, that’s quite…

I encourage you to follow the links through to the Swift Evolution proposals for more information, and if you missed my earlier what's new in Swift 5.1 article then check that out too.

This is best understood as an example, so here’s a User type that defines four properties:struct User { let name: String let age: Int let bestFriend: String?

This is particularly apparent when working with SwiftUI code, where Swift would often produce false positive error messages.

In Swift 5.1 this caused an error for the frame() modifier saying 'Int' is not convertible t…

Shuffling the array is how we're simulating you changing the items, because it forces the list to update its rows.

The one-line fix for slow SwiftUI listsI'm going to show you exactly why this happens in just a moment, but first I want to show you the one-line fix.

We've told SwiftUI that this list has a unique identifier, and that identifier is a new UUID every time.

Without the id() modifier, SwiftUI realizes the list is actually the same one and so it doesn't change it.

That's why our one-line fix works so well: we're making SwiftUI think the list itself is different so it doesn't try to look inside it to figure out the differences itself.

So, once again I’ve written this Year in Review post to help summarize what I worked on, what results that work had, and what I’m planning for 2020.

That’s 200 days of Swift tutorials, 40 days of Xcode tips, 400 videos, 400 pages of a SwiftUI book, 20 livestreams, plus an iOS app.

2019 was the year I also ran my own conference for the first time: Hacking with Swift Live.

Although I had planned to cut down on the number of conferences I spoke at in 2019, I still managed to speak at 12.

I even managed to add a dedicated search feature – another item on my list of 2019 goals checked off!

Swift gives us map() , compactMap() and flatMap() methods, but although they might sound similar they do very different things.

, which is an optional optional integer.

Broadly speaking, any time you see an optional optional anything something has gone wrong and you should rethink.

To be clear, an optional optional means:The outer optional might exist and the inner optional might exist.

Optional optionals are deeply confusing to work with, but this is where flatMap() comes in: it also performs a transformation (the “map” part of its name), but then flattens what comes back so that “optional optional” just becomes “optional”.

iOS 13 introduced new type-safe initializers for Core Image filters that allow us to use them much more easily – and without having to hope that our code works at runtime.

Previously much of Core Image was stringly typed, meaning that we would create filters using strings, which in turn meant that Swift couldn't be sure that when we asked for a value to be set that it would actually exist.

iOS 13 replaces that with a much better implementation, and you'll never want to go back to the old way.

Start by adding an import to bring in all the new types:import CoreImage import CoreImage.CIFilterBuiltinsNow you can go ahead and create filters using static methods on CIFilter .

For example, we coul…

Apple just updated its Swift Playgrounds iPad app with support for Swift 5.1, dark mode, and SwiftUI, which means it’s now possible to try building SwiftUI apps and components entirely on your iPad.

Although Swift Playgrounds comes with a handful of templates for various kinds of projects, none of them are for SwiftUI – at least not yet.

And don’t forget that even without SwiftUI you still get all the benefits of iOS 13, including the new Swift 5.1 opaque return types, Combine, and more.

If you’d like to learn more about how to use SwiftUI to build apps, you should read my free online book: SwiftUI by Example.

You might also want to try my 100 Days of SwiftUI course, which teaches you Swift…

This will mostly be additions to my Swift Knowledge Base, but there will be some longer ones too.

So, if you’re following the 100 Days course and Swiftoberfest you’ll get two new articles every day.

Some will be easier and some harder, but I feel confident you’ll learn something new during Swiftoberfest.

SwiftUI articlesEvery day I’ll write a new chapter in SwiftUI By Example and link to it below.

If you're looking for free SwiftUI tutorials, I have just the thing for you: the 100 Days of SwiftUI is an all-new online course teaching you how to build a variety of real-world apps with SwiftUI.

The course starts with the same 15-day Swift fundamentals from the original 100 Days of Swift, but the next 85 days are all-new, project-based tutorials teaching SwiftUI.

Some folks have asked whether the 100 Days of SwiftUI will be reusing material from my existing SwiftUI book, SwiftUI by Example.

Today is the first day of the 100, and if you start today you finish on December 31st – just in time to start 2020 off with an incredible new skillset.

So, if you want to take onboard the exciting new…

For example, the gap between Swift Playgrounds and Xcode’s playgrounds is far too big, and just creates a learning chasm where really there ought to be none.

There are a few options here:Apple adds the features from Swift Playgrounds into Xcode playgrounds.

Apple does a straight port of Swift Playgrounds to macOS, either using Catalyst or building a native AppKit/SwiftUI release.

Apple does an enhanced port of Swift Playgrounds to macOS, then adds some features from Xcode into Swift Playgrounds so the tool becomes even more useful.

Again, this won’t sound great to experienced developers who just want simple, searchable text documentation, and it’s true that I find Apple’s SwiftUI tutorials …

Julian Schiavo writes, “I'm using a Set to make sure my array only contains uniques, but each object in the set has a date variable.

Here’s an example NewsStory struct that tracks an ID, a title, plus a date:struct NewsStory { var id: Int var title: String var date = Date() }As you can see, I’ve made the date automatically assigned so that it’s always the current date.

Using that struct we can create three news stories like this:let story1 = NewsStory(id: 1, title: "What's new in Swift 5.1?")

So, we need to update the NewsStory struct to this:struct NewsStory: Hashable { var id: Int var title: String var date = Date() }And now our code works – so far, so good.

Two months ago Hacking with Swift passed 25 million page views, which is a huge accomplishment that I’m really proud of.

I wanted to celebrate with something special, so I decided it was time to implement our #1 most requested feature: site search.

Of course, when I sat down to actually make site search happen I ended up changing practically everything else at the same time, and the result was the third major site update for Hacking with Swift.

Let me talk you through what’s changed…Site search at lastYes, I set out to make site search work, and obviously it would suck if that got missed out during the big refresh!

Site search, dark mode, better navigation, and more speed are all nice to ha…

In this accessibility tutorial, you’ll improve the accessibility of a SwiftUI app by making it responsive to some common user accessibility settings.

It lists these accessibility options:Invert colors @Environment(\.accessibilityInvertColors) : The Smart Invert accessibility option reverses the colors of the display, except for images, media, and some apps that use dark color styles.

The Accessibility options include those in the Accessibility Inspector Settings tab, but also these:Bold Text @Environment(\.legibilityWeight) : This accessibility option displays all text in boldface characters, so large font text uses even more space.

On/Off Labels UIAccessibility.isOnOffSwitchLabelsEnabled :…

This course is for experienced developers, with at least an intermediate knowledge of Swift and iOS, who want to learn about the Photos Framework.

In this accessibility tutorial, you’ll organize the accessibility information of a SwiftUI app by restructuring its accessibility tree.

Calculating Color Contrast RatioThere are online color contrast calculators, but Accessibility Inspector has its own.

Then open its Color Contrast Calculator: Windows▸Show Color Contrast Calculator.

Better Labels for All UsersEach list item displays sample text in a randomly-generated text color against a randomly-generated background color.

Swipe right to hear the text color value, then swipe right again to hear the background color value.

Use the SwiftUI Accessibility API attributes.

Some familiarity with SwiftUI will be helpful: Check out our tutorial SwiftUI: Getting Started if you need a refresher.

When the accessibility built into SwiftUI doesn’t provide the right information in the right order, you’ll use the SwiftUI Accessibility API to make your accessible elements understandable, interactable and navigable:Understandable: In this first part of this tutorial, you’ll learn what SwiftUI generates for VoiceOver from SwiftUI element initializers.

SwiftUI uses these to generate an accessibility element:The accessibility label defaults to the element’s label Hide Visited.

You can initialize many of the SwiftUI control views…

Master declarative asynchronous programming with Swift using the Combine framework!

Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work — delegates, notification center, KVO, closures, etc.

With Apple’s introduction of the Combine framework in WWDC 2019, it is clear that Apple aims to position declarative and reactive programming in Swift as a long-term investment and a game-changer in how developers perform and compose pieces of asynchronous work, making it a must-have tool at your disposal.

Combine is Apple’s framework to work with asynchronous events in a unified and reactive way that ensures your app is…

Learn how to build web apps and web APIs using Swift and the Vapor framework!

If you’re a beginner to web development, but have worked with Swift for some time, you’ll find it’s easy to create robust, fully-featured web apps and web APIs with Vapor 3.

Whether you’re looking to create a backend for your iOS app, or want to create fully-featured web apps, Vapor is the perfect platform for you.

This book starts with the basics of web development and introduces the basics of Vapor; it then walks you through creating APIs and web backends; creating and configuring databases; deploying to Heroku, AWS, or Docker; testing your creations and more!

Install the menu into the app and add custom actions to it.

You'll be able to delete cells and also use your shapes grid to choose the shape of each cell.

In this Alamofire tutorial, you’ll build an iOS companion app to perform networking tasks, send request parameters, decode/encode responses and more.

This property does not contain all of the starship data, but rather an array of endpoints to the starship data.

Creating a Data Model for StarshipsBefore fetching any starships, you first need a new data model to handle the starship data.

Fetching the Starship DataTo fetch the starship data, you’ll need a new networking call.

You’ll see a detail view that’s fully populated with film data and starship data.

In this iOS accessibility tutorial, learn how to make apps more accessible using VoiceOver and the Accessibility inspector.

The quickest way to use VoiceOver is to open the Settings app on your iOS device, select Accessibility ▸ Accessibility Shortcut then select VoiceOver.

Fortunately, there’s a tool to help named Accessibility Inspector, which does the following:Runs through your app and finds common accessibility issues.

The Accessibility Inspector currently offers only these five options, but Apple plans to add more in the future.

Then you used the Accessibility Inspector to perform audits, look at accessibility element values and perform live dynamic changes to invert colors or change …

This course is for Advanced iOS developers interested in mastering the all-new MetricKit and for developers interested in using Swift on the server in a production environment.

It expects you to have advanced knowledge in the Swift language and the iOS eco-system.

Prior experience using Vapor is advantageous.

In this tutorial, you’ll learn how to use unsafe Swift to directly access memory through a variety of pointer types.

Lisp FORTRAN COBOL ( defun square ( x ) ( * x x )) ( print ( square 4 )) ;; 16 pure function square ( x ) integer , intent ( in ) :: x integer :: square square = x * x end function program main integer :: square print * , square ( 4 ) end program main !

If you’re also confused, we think the following table can help clear things up:Static Dynamic Type init N/A Instance call As Function @dynamic Callable Member func @dynamic Member LookupSwift has always had static callable types and type members.

Static Callablestruct Static { init () {} func call As Function () {} static func function () {} func function () {} }This type can be called statically in the following ways:let instance = Static (…

RawRepresentable with C Raw Value TypesThe primary motivation for raw value enumerations is to improve interoperability.

Here’s what we need to make that happen:enum Node Type : Raw Representable { case document case block Quote … init ?

RawRepresentable and Associated ValuesIn Swift, an enumeration case can have one or more associated values .

RawRepresentable as Raw Values for Another EnumerationConsider the following from the Raw Representable docs:For any enumeration with a string, integer, or floating-point raw type, the Swift compiler automatically adds Raw Representable conformance.

init ( raw Value : value ) ! }

But to anyone aspiring to be an NSHipster, knowledge of every @ directives is tantamount to a birder’s familiarity with the frenetic hovering of a hummingbird, the commanding top knot of a Mountain quail, or the eponymous “cuckoo” of Coccyzus americanus.

Protocol methods are required by default.

@selector() and @protocol() serve as pseudo-literal directives that return a pointer to a particular selector ( SEL ) or protocol ( Protocol * ).

@defs() Provides the layout of an Objective-C class.

If you so much as glance towards an unavailable class or method, it could mean curtains for your app.

static void direct Function ( My Class * __unsafe_unretained object );Here’s how each of these approaches translates to the call site:My Class * object = [[[ My Class ] alloc ] init ]; // Dynamic Dispatch [ object dynamic Method ]; // Direct Dispatch direct Function ( object );Direct MethodsA direct method has the look and feel of a conventional method, but has the behavior of a C function.

Likewise, the methods for an Objective-C property can be made direct by declaring it with the direct property attribute.

__attribute__ (( objc_direct_members )) @implementation My Class - ( BOOL ) direct Property { … } - ( void ) dynamic Method { … } - ( void ) direct Method { … } - ( void ) direct Exten…

In Swift, you use the @available attribute to annotate APIs with availability information, such as “this API is deprecated in macOS 10.15” or “this API requires Swift 5.1 or higher”.

When used to designate Swift language availability for an API, the @available attribute takes the following form:@available ( swift version )Unlike platform availability, Swift language version annotations don’t require an asterisk ( * ); to the compiler, there’s one Swift language, with multiple versions.

Historically, the @available attribute was first introduced for platform availability and later expanded to include Swift language version availability with SE-0141.

The syntax of an #available expression res…

This week on NSHipster: a quick look at the bless command and the macOS boot process.

If you search the Web for “how to set Boot Camp as startup disk from Terminal”, you’ll find plenty of old blog posts that mention bless .

Long before Boot Camp, in the early days of Mac OS X, one of the common uses of the bless command was booting into your “Classic” Mac OS 9 partition: # Boot into Mac OS 9 sudo bless -folder9 '/Volumes/Mac OS 9/System Folder' -set OF # Boot into Mac OS X sudo bless -folder '/System/Library/Core Services' -set OFTo get an overview of the blessed volumes on your machine, run bless --info :If you’re on a Mac booted from an APFS disk, you’ll need to prepend sudo to run the bl…

Visual Studio Code (VSCode) is a cross-platform text and source code editor from Microsoft.

This week, we’ll walk through the process of how to get started with Swift’s new Language Server Protocol support in Visual Studio Code on macOS.

Step 1: Install Visual Studio CodeDownload Visual Studio Code and install it to your system Applications folder.

You’ll need to have the code command accessible from $PATH in order to install the SourceKit-LSP extension later on.

To enable it, open Xcode, select the “Xcode > Preferences…” menu item ( ⌘ , ), navigate to Components and choose Swift Development Snapshot.

What the Language Server Protocol does is change this M × N problem into a M + N problem .

How Language Server Protocol WorksIf you’re an iOS developer, you may be most familiar with the terms server and protocol in the sense of communicating with web applications in JSON format via HTTP.

This actually isn’t too far off from how the Language Server Protocol works.

Language Server Protocol Support in Clang / LLVMIf the M + N diagram from before looks familiar, it might be because it’s the same approach taken by LLVM.

In its recent 5.0.0 release, Clang added a new tool called Clangd, LLVM’s implementation for the Language Server Protocol.

let utterance = AVSpeech Utterance ( string : string ) let synthesizer = AVSpeech Synthesizer () synthesizer .

; AVSpeech Utterance * utterance = [[ AVSpeech Utterance alloc ] init With String : string ]; utterance .

import AVFoundation let text = "It's pronounced 'tomato'" let mutable Attributed String = NSMutable Attributed String ( string : text ) let range = NSString ( string : text ) .

As we’ll see in this week’s article, good developer habits start with #pragma mark .

You are on a Mac and want to run or test one of your SwiftPM packages on Linux? Here’s how, using Docker.

Running the Docker container

First, download, install, and run Docker Desktop for Mac.

In Terminal, switch to the directory of the Swift package you want to test.

Then run this command:

docker run --rm --privileged --interactive --tty \ --volume "$(pwd):/src" \ --workdir "/src" \ swift:latest This tells Docker to create a Linux container with the latest Swift version installed and open a shell in it. The first time you run it, Docker will need a few seconds to download the image for the container; subsequent runs will be instantaneous. Older Swift versions

To test on older Swift version…

In 2017, I wrote an article titled Keeping XCTest in sync on Linux. In it, I proposed to add some code to your test classes that would alert you when you forget to update the allTests array after adding a test method.

Swift 5.1 ships with a much better solution: automatic test discovery on non-Apple platforms, such as Linux and Windows.

This feature is not yet enabled by default. You have to pass the flag explicitly for now:

swift test --enable-test-discovery While XCTest on Apple platforms uses the Objective-C runtime to find test methods, this command looks them up in an index created by the compiler during build time. (This index also powers SourceKit-LSP.)

How to test your SwiftPM packa…

Unlike other views, modal sheets in SwiftUI do not inherit the environment from their parent.

And because Text grabs its font from the environment, all text views in this section of the view tree are rendered with a larger font size.

Here’s the code for the root view:struct RootView : View { var body : some View { RootViewContent () .

locale , Locale ( identifier : "ja_JP" )) } } struct RootViewContent : View { @State var isPresentingSheet = false @Environment(\.sizeCategory) var sizeCategory var body : some View { VStack ( spacing : 16 ) { Text ( "Root View" ) .

Propagating environment values manuallyIf you want to propagate an environment value to a sheet, you must do so manually.

We can do this with ForEach :struct PeopleList : View { var people : [ Person ] var body : some View { List { ForEach ( people ) { person in Text ( person .

I usually prefer zip over enumerated for this reason, so let’s use it here:ForEach ( zip ( 1 ... , people )) { number , person in Text ( " \( number ) .

func numbered ( startingAt start : Int = 1 ) -> [( number : Int , element : Element )] { Array ( zip ( start ... , self )) } }This makes call sites quite a bit nicer:ForEach ( people .

id ) { number , person in Text ( " \( number ) .

1 ) } } }And now we can conditionally conform the Numbered struct to Identifiable when its element type is Identifiable :extension Numbered : Identifiable …

Speaking of the Combine framework, I find it interesting that Combine had to introduce a formal concept for top-level decoders in order to implement its decode and encode operators.

In fact, neither the standard library nor Foundation have any formal notion of so-called top-level decoders at all.

Combine then retroactively extends the built-in coders to conform them to the new protocols:extension JSONEncoder : TopLevelEncoder {} extension JSONDecoder : TopLevelDecoder {} extension PropertyListEncoder : TopLevelEncoder {} extension PropertyListDecoder : TopLevelDecoder {}This finally allows Combine to define a generic decode method that is generic over a TopLevelDecoder :extension Publisher …

In March 2018, I wrote a piece titled Making illegal states unrepresentable, in which I argue that the “correct” result type for URLSession completion handlers is Result<(Data, URLResponse), (Error, URLResponse?

In other words:If the network requests succeeds, you receive (Data, URLResponse) — the response body as Data and a URLResponse representing the response metadata.

URLSession.DataTaskPublisherBut the introduction of the Combine framework gave Apple a chance to revisit the result type of a URLSession data task in a Swift-only context.

tuple as a failure type because a publisher’s failure type must conform to the Error protocol and tuples can’t do that (for the same reason, the result …

Some are in German, some in English, but you should be able to find translations for most of them.

No tech book made the list this year (I didn’t finish any).

Daytripper is a masterpiece, and Pascal Jousselin’s Unschlagbar series (Imbattable in French and Invincible in English) is super funny and creative.

Another theme: coming-of-age stories set in the 1990s in post-reunification East Germany (Oder Florida and Als ich mit Hitler Schnapskirschen aß.

Lukas Rietzschel’s Mit der Faust in die Welt schlagen from last year’s list also belongs to this theme.)

The fourth edition of our book Advanced Swift is available now.

Advanced Swift is the book for people who have read The Swift Programming Language and/or have been using Swift for some time and now want to dig deeper and really understand how everything works.

The chapters on Strings, Collection Protocols, and Error Handling also have substantial revisions and/or new content.

We moved the Collection Protocols chapter further back in the book, resulting in a smoother learning curve for readers.

In five separate episodes, Chris and Florian demonstrate C Interoperability, String Parsing, Collection Protocols, Functions, and Encoding & Decoding Graphs.

In episode 1 of the new Swift Community Podcast, Chris Lattner, Garric Nahapetian, and John Sundell spoke about the origins of Swift and the current state of the Swift community, among other things.

You’ll see I mainly quoted Chris Lattner because I think his account of how Swift was created is the most relevant to preserve for posterity.

Now, Craig is a really, really interesting person.

On popularizing Swift outside the Apple community(Starting at 50:18)Chris Lattner: While this has been a very upbeat, positive discussion about Swift, Swift also has lots of problems.

“Here’s how to do that in a UIViewController .” Chris Lattner: Exactly.

Listed in the order I read them.

The list includes some fiction, some non-fiction.

Few tech books.

Some are in English, some in German.

Some on serious topics, some light entertainmen, one children’s book, and one photo book.

Small Fry, the memoir of Lisa Brennan-Jobs, is one of the best books I’ve read this year.

Steve was absent for the first six or seven years of Lisa’s life, but the two later became close.

Throughout her adolescence, Lisa is conflicted how to divide her loyalty between her parents, and they don’t make it easy for her.

I’d built up the courage, after talking with Mona [Simpson, Lisa’s aunt, Steve’s sister].

I should have bought her the best gifts because she had less money and couldn’t buy them for herself.

For collections, this is straightforward:extension Collection { var headAndTail : ( head : Element , tail : SubSequence )?

{ guard let head = first else { return nil } return ( head , dropFirst ()) } } if let ( firstLetter , remainder ) = "Hello" .

next () else { return nil } let tail = AnySequence { iterator } return ( head , tail ) } }This code works, but it’s not a nice generic solution, especially for types that also conform to Collection .

Here’s his code (slightly modified by me for style):extension Sequence { var headAndTail : ( head : Element , tail : SubSequence )?

= nil let tail = drop ( while : { element in if first == nil { first = element return true } else { return false } }) …

I recently read Roy Fielding’s 2000 PhD thesis, Architectural Styles and the Design of Network-based Software Architectures, in which he introduced and described REST.

As mentioned, Fielding’s dissertation is from 2000, but he began developing the ideas that later became REST as early as 1994.

He also co-founded the Apache web server project.

Cookie interaction fails to match REST’s model of application state, often resulting in confusion for the typical browser application.

Fielding’s focus in the dissertation is markedly different from how developers discuss REST today.

As you access the photo library, you’ll see Core Data logging debug information to the Console.

Finding PhotoKit’s Core Data modelIn my quest to understand the Photos framework better (especially its performance characteristics), I wanted to inspect its data model.

I found a file named PhotoLibraryServices.framework/photos.momd/photos-10.0.mom deep in the bowels of the Xcode 10.0 app bundle:/Applications/Xcode-10.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/photos.momd/photos-10.0.momOpening compiled Core Data models in XcodeA …

Voice Boost 2 achieves the same goal as the original Voice Boost, but with dramatically more sophisticated methods, leading to more consistent results and much better sound quality.

Voice Boost 2 also incorporates a dynamics compressor, but over time, I’ve kept reducing its strength as I’ve found it less necessary.

Voice Boost 2’s limiter performs true-peak detection, rather than simply measuring sample peaks, to avoid this type of clipping and further reduce distortion.

It’s not promoted more in the app or even labeled “Voice Boost 2”.

Voice Boost 2 is in today’s update (2020.1), along with these new features:AirPlay 2: Overcast can now play to HomePods and other AirPlay 2 devices much mor…

In light of today’s rumor that a Pro Mode may be coming that seems to offer benefits in the opposite direction,1 I wanted to re-make the case for a Low Power Mode on macOS — and explain why now is the time.

The sole exception, Low Power Mode on iOS, seems to be a huge hit: by offering a single toggle that chooses a different balance, people are able to greatly extend their battery life when they know they’ll need it.2Mac laptops need Low Power Mode, too.

I’ve been disabling Intel Turbo Boost on my laptops with Turbo Boost Switcher Pro most of the time since 2015.

When Turbo Boost is enabled, the fans annoyingly spin up every time the system is under a heavy sustained load.

When Turbo Boos…

After my first day with the new 16-inch MacBook Pro, I’m very optimistic about it.

But USB-C is gradually becoming more common, and dongles are slowly — very slowly — getting less shitty.

But USB-C is gradually becoming more common, and dongles are slowly — very slowly — getting less shitty.

The new 16-inch MacBook Pro is a great computer in most other ways, but so were the MacBook Pros from the last few years.

Following in the footsteps of the fantastic iMac Pro, updated Mac Mini, and upcoming Mac Pro, the release of the 16-inch MacBook Pro ends a painful chapter of neglect and hubristic design of the Mac.

Today’s Overcast update (2019.6) brings some great new features.

Rather than shipping a big iOS update, a standalone Watch app, and a Mac app on day one, these will probably come incrementally over the next year.

90 seconds should be better — most clips won’t need to be that long, but it’ll be nice to have the headroom when you need it.

But after five years, only 10% of active users have connected a Twitter account in Overcast, and only 0.2% of new podcast subscriptions have actually been added via Twitter recommendations.

Overcast now offers its own data-driven recommendation engine, and I’ve removed Twitter integration entirely.

It was a rough time to be a pro Mac user.

Over the next few years, it became clear that the Mac Pro was an embarrassing, outdated flop that Apple seemed to have little intention of ever updating, leaving its customers feeling unheard and abandoned.

I think Apple learned a small lesson from it, but they learned a much bigger one a few years later.

It sounded like they’d gone from not listening to their customers at all to an institutionalized process of listening.

It’s hard to tell when Apple is listening.

Sharing podcasts has never been easy, but I’ve always tried to lead the way with Overcast, with publicly shareable episode links and optional recommendations from your Twitter friends since version 1.0 in 2014.

Podcast sharing has been limited to audio and links, but today’s social networks are more reliant on images and video, especially Instagram.

So people mostly just haven’t shared podcast clips, understandably, because it has been too hard.

You can generate an audio clip, or portrait, landscape, or square video, using your current Overcast theme setting.

So go get Overcast and start sharing your favorite moments.

▶️The first thing someone does in a podcast app is add some podcasts, and most active Overcast users add at least two new podcasts each month.

Over 80% of podcasts are added to Overcast by searching, with the vast majority as searches for a specific podcast by name (rather than searching for generic keywords, such as “business”).

Good search is a critical, differentiating feature of any podcast app.

I’ve been building toward this by analyzing years of popularity statistics and anonymous search data.

Instant Search is the next step in Overcast’s search evolution.

Watch my video review of the new iPad Pro in both sizes.

Rather than try to be comprehensive, I focused on what matters most to me: size choice between the 11” and 12.9”, the Smart Keyboard Folio from my perspective as a frequent 10.5” Smart Keyboard user, the new Pencil, and why “getting work done” isn’t important to me.

The i7 Mac Mini scored better on single-core performance than every other Mac today (!)

at 5912, and its multi-core score of nearly 24,740 beats every Mac to date except the iMac Pro and the old 12-core 2013 Mac Pro.

“Performance-competitive with pro Macs” was not high on my prediction list for a Mac Mini update, but here we are.

I Can’t Believe The Mac Mini Is This Awesome, I Can’t Even Say “Again” Because It Never WasA new Mac Mini could’ve been so much worse.

Of course, with Apple’s track record on the Mac Mini, it may never be updated after this.

And it’s absolutely possible to design a highly legible dial with hour indices in many different styles.

The hour hands nearly touch the hour indices.

While Explorer omits minute markings altogether, Simple bafflingly uses 30-second markings in place of its minute track, making time-telling even harder.

Infograph is similar, but even worse: its hour indices are more faint, it uses 30-second markings instead of minute markings, and its default Calendar display wipes out the top three indices.

It’s great for Apple to offer a wide variety of Apple Watch faces, but most of them are short-lived novelties at best.

You see, Overcast’s previous Apple Watch app really sucked.

After a very busy summer, standalone Apple Watch playback is back in Overcast, and it’s actually good this time!

Finally, the best way to use Overcast from your Apple Watch isn’t to delete it, letting the Now Playing app show up instead.

Some of the highlights:Search your podcasts and current episodes from the main screen, or go into a podcast’s screen to search its entire archive.

your podcasts and current episodes from the main screen, or go into a podcast’s screen to search its entire archive.

Laptop battery life is decreasingly relevant to me as more airplanes offer power outlets.

Sometimes, you just need Low Power Mode: the switch added to iOS a few years ago to conserve battery life when you need it, at the expense of full performance and background tasks.

Since then, I’ve been running Turbo Boost Switcher Pro to automatically disable Turbo Boost when I’m running on battery power, and it has been wonderful: I made it through that 8-hour flight only because Turbo Boost was off.

It roughly doubles compilation times, but also doubles the battery life.

The best bang-for-the-buck option is still to just disable Turbo Boost.

Overcast 4.2 is out now.

68% of Overcast accounts have email addresses today.

To reduce that as much as possible, I’ve made major changes to account handling:The previous login screen (left) and the new one.

In Overcast 4.2, the login screen now prominently encourages anonymous accounts by default.

In Overcast 4.2, much like Mail (and for the same reason), remote images don’t load by default.

Overcast 4.1 is now in the App Store with some small but nice new features.

Delete episodes 24 hours after completion: Before, episodes could either be auto-deleted immediately upon completion, or not at all.

Password-protected podcasts: Some private podcast feeds, including many paid and members-only podcasts, require a username and password via HTTP Basic Auth.

iPhone rotation has always been disabled by default, and had been buried in Nitpicky Details for a long time, so very few people have ever used it.

iPhone rotation has simply proven far too costly to maintain for its extremely low usage, and it had to go to free up more of my time for more highly demanded features.

Before the native development kit was ready, Apple tried to pass off web apps as a “sweet solution” for third-party apps, but nobody was fooled.

* * *Developing Apple Watch apps is extremely frustrating and limited for one big reason: unlike on iOS, Apple doesn’t give app developers access to the same watchOS frameworks that they use on Apple Watch.

But unlike the iPhone’s web apps, WatchKit doesn’t appear to be a stopgap — it seems to be Apple’s long-term solution to third-party app development on the Apple Watch.

But this sweet solution is the only choice anyone else has to make Apple Watch apps.

There are only two ways to meaningfully improve Watch apps, spur third-party innovation, and …

👋 Get in Touch

We are @swift_unwrapped on twitter. Follow us, ask us a question, let us know what you think of the show! If you want to follow us individually, we're @jesse_squires and @simjp. 🖤 Leave A Review

If you're enjoying the show. The best and easiest way to show your support is by heading over to iTunes and leaving us a review! Not only do you let us know what you like about the show, but you're also helping other Swift language folks find the show.

Head over to our iTunes page to share your opinion of the show!

We discuss a recent Swift Evolution pitch from Ben Cohen on Modify Accessors.

The way Swift reports compilation diagnostics like errors, warnings and fixits is about to improve in Swift 5.2.

Would you like some Swift in your Swift? The compiler driver is getting a shiny new implementation in Swift and there's no shortage of opportunities to contribute.

The Swift of tomorrow... today! The Standard Library Preview Package would allow you to try out upcoming Swift features before they officially ship with new language versions.

We invite special guest, Doug Gregor, back to the show to discuss all things Swift 5.1

What's one feature missing from the Swift Package Manager that CocoaPods has had for years? Binary dependencies! But how would this work in SPM?

We discuss the new generic math functions coming to Swift, as well as approximate equality for floating point numbers.

A concept that's been in and out of conversation for Swift since 2015, property behaviors - uh, delegates - uh, wrappers - are now back with the full weight of SwiftUI behind it.

In this episode with special guest Keith Smiley, we cover the growing number of tools that let you build things in Swift, a few of which are made by Apple, as well as some others like CMake, Bazel and Buck.

Although we usually discuss new features being added to Swift, this episode is all about removing things from the language.

SR-9749: The bug that led to deprecating encodedOffset Thanks to this episode's Sponsors Sentry.io

Sentry tells you about errors in your code before your customers have a chance to encounter them.

With Sentry, you’ll see exactly how many users have been impacted by a bug, the stack trace, the commit that the error was released as part of, the engineer who wrote the line of code that is currently busted, and a lot more.

Give it a try and let them know we sent you at https://www.sentry.io/for/swift Clubhouse.io

Clubhouse is the first project management…

In what is sure to lead to significant community discussion, there's now a pitch for adding a style guide and formatter to Swift.

​

If this proposal is accepted, we'll be seeing Key Paths in a lot more places.

The Swift project is working on official support for the industry-standard Language Server Protocol and we can barely contain our excitement.
