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.

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…

With this change, other conformances such as `Codable` might make sense for tuples as well.

It also makes sense to implement other conformances for other structural types in the language such as metatypes being `Hashable` , existentials being `Equatable` and `Hashable` , etc.

In the future when we have proper tuple extensions along with variadic generics and such, implementing these conformances for tuples will be trivial and I imagine the standard library will come with these conformances for tuples.

When that happens all future usage of those conformances will use the standard library's implementation, but older clients that have been compiled with this implementation will continue using …

I got metadata rejected and they asked me a few questions. I replied to them. Today they replied and told me that the name of my app is not in compliance and I need rights to use it. I then modified the name and I needed to change images inside the app. Once that was done I resubmitted the app and replied to the message explaining what I did. Did I do everything correctly?

I've read comments saying that junior iOS job positions are extremely scarce, and the few that are available require ObjC knowledge. Is this true? Would you say it's better to break into the field via backend webdev, then switch to mobile/iOS when the time is right? Assuming I'm focused on backend webdev but do some personal iOS on the side, should I stick with just UIKit or do I learn SwiftUI? Are there more junior android jobs than iOS jobs? submitted by /u/DesperateSmoke [link] [comments]

I got an initial metadata rejection so the app reviewer could clarify some information about the app. Today I got a reply from them saying I violated 4.1 copycats in which I had a name that was already copyrighted.

Hey guys! Relatively new to Swift, and been thinking about a problem: how would I go about examining and comparing different parts of an image? For instance, one function of my app is to check an image (let's say, a predominantly blue painting) and see if as I go from left to right, the color gradually grows lighter and lighter. I'm thinking that the function I'd write basically would 1) check that each color value for a pixel is greater than the one on its left, and 2) highlight where this property is violated. But how would I actually implement and examine the image? Is that based in ARKit? Thanks so much, in advance! submitted by /u/jalopyphoenix [link] [comments]

CodeBuilding an adaptive button I linked to several posts from Jeff Watkins on leveraging UIButton rather than replacing it last month.

I do like that he says this though: There’s still no excuse for using UITapGestureRecognizer to solve this problem.

Propagating user-facing errors in Swift It's always easy to overlook error handling, especially if you're writing blog posts or sample code.

😂 It's understandable of course, handling errors isn't trivial, and if every sample code project included thorough error reporting, it'd detract from what samples were demonstrating.

I did like this article in which he argues that with Combine, Swift already has what Chris proposed.

I know I wrote about virtual community events three weeks ago, but things are moving fast, and more are launching every day, so here’s a quick follow-up.

Swift World which kicked off on Monday.

Both of these have full schedules of workshops/talks coming up, so check them out even if you missed their opening sessions.

Then, the virtual conferences start.

Are there any other virtual conferences I’m missing?

Remember ArgumentParser ?

Well, what if someone used it to build a tool to create entire SwiftUI apps from the command-line... and no, it doesn’t generate source code, it generates entire.

apps... from a command-line tool.

😬You should probably see it to believe it...

I honestly don't know how I feel about this.

I noticed the WWDC app turned into the Apple Developer app back in November last year and it felt like such a small change I don't think I even mentioned it here.

This week I realised there's a whole feed of developer news that's seemingly only available from the app, and not on the web.

With blog post style articles, links to old WWDC videos, and even developer profiles!

I've wanted Apple to do blog post style delivery of things like this for a very long time.

Even worse, the RSS feed linked from the blog post style pages is a feed that doesn't include any of this new style content, it's just the regular news RSS feed!

I've seen plenty of high-level descriptions of how this is going to work, but this article from Mattt is the first one that goes into technical details around the framework.

Health organisations around the world would not have been able to do this alone, so I'm incredibly happy to see Apple and Google work together to make a cross-platform, privacy-conscious solution like this.

👏On the same subject, Quentin Zervaas has put together a small sample app that's worth a look.

It seems like, at least as of yesterday this is still happening.

It's hard to know what's going on here, but testing purchasing logic is hard enough at the best of times, without instability in the sandbox.

I hope this gets resolved very soon.

Oh, and this status page which shows status, as well as history, on the availability of these systems might be helpful if you're experiencing problems.

Universal iOS/macOS purchases arrived last week, and the first app I saw take advantage of them was Geoff Hackworth's wonderful Adaptivity.

He also wrote up a fantastic article about the transition from iOS to Catalyst.

Oh and don't worry too much about what Geoff says at the bottom of the post about issues with universal purchases not working, I think it was just teething troubles.

When I opened the Mac App Store, it instantly showed a download button as I had already purchased the iOS version.

UPDATE: Looks like it might not have just been a teething issue, thanks for the clarification Geoff!

Xcode 11.4, Swift 5.2, ARKit 3.5 , Universal purchase for macOS and iOS apps, 20 new countries for the App Store, and new hardware too.

It’s been quite a week for Apple.

🙌Apple has extended to the deadlines for a few upcoming App Store changes.

There's no mention of extending the deprecation of UIWebView deadline for new apps which we have to presume is still happening in April.

I don't think that's a huge issue though, as it doesn't affect apps already on the store.

This will mark the second major feature film deal for Apple TV+ recently.

Last week, Apple TV+ secured the rights to the upcoming World War II film Greyhound which was written by and stars Tom Hanks for $70 million.

A report in April first indicated Apple’s interest in funding the Martin Scorsese film, which is based on a best selling book of the same name.

We’ve heard rumors about a new Apple TV for a while, but the company still sells two different Apple TV models, which leads some customers to wonder which one they should buy or whether they should wait for the next generation.

The current lineupIf you’re planning to buy an Apple TV today, you have two options: the Apple TV 4K (5th generation) and the Apple TV HD (4th generation), but neither of them are brand new models.

What we know about a new Apple TV9to5Mac has found references to a new Apple TV model in the tvOS 13.4 beta code.

The codes reveal a new Apple TV with the codename “T1125”, while the current Apple TV 4K is named “J105a” and the HD model is “J42d”.

Apple has acquired the machine learning startup Inductiv Inc., according to a new report from Bloomberg.

The report explains that the engineering team from Inductiv has joined Apple “in recent weeks” to work on several different projects including Siri, machine learning, and data science.

Having clean data is important for machine learning, a popular and powerful type of AI that helps software improve with less human invention.

In 2016, Apple acquired the Seattle-based startup Turi as part of its efforts to build out its machine learning and artificial intelligence teams.

Apple went on to release the Turi Create framework for simplifying the development of machine learning models.

Tired of using the low-res 720p FaceTime camera built-in to your MacBook Air, Pro, or iMac?

Canon just expanded its beta software to macOS today that lets you use an EOS or PowerShot camera as your webcam for much-improved video quality.

Well if you have a compatible Canon EOS or PowerShot camera, you can now use it for high-quality webcam video with your Mac.

Unfortunately, there are some limitations since the EOS Webcam Utility is in beta, like no support for FaceTime or Safari, and you need to use the web versions of Zoom, Skype, etc.

Apple last week released iOS 13.5 to everyone, bringing new features such as the Exposure Notification API and Face ID upgrades.

Now, Apple has stopped signing iOS 13.4.1, which means users can no longer downgrade from iOS 13.5 to iOS 13.4.1.

Of note, there is currently a jailbreak available for iOS 13.5, so there’s no need to downgrade to iOS 13.4.1 to take advantage of it.

Now that Apple has stopped signing iOS 13.4.1, it means that no one can downgrade from iOS 13.5 to that version via iTunes/Finder.

As for right now, iOS 13.5 is the latest version of iOS, and it’s still being signed and supported by Apple.

This morning, HBO launched its new expanded streaming service: HBO Max, which is a superset of the existing HBO Now offering.

You can get the HBO Max app on all Apple devices, but it comes at a price: the HBO partnership with Apple TV Channels is being wound down.

Starting today, the HBO channel has been removed from the Apple TV app if you don’t already subscribe to it.

The HBO Apple TV channel now features a carousel advertising the Max service.

If you are coming to HBO Max afresh, you can use Apple In-App Purchase to subscribe inside of the HBO Max application.

Apple could be planning a redesign for the Apple Watch Leather Loop.

A tipster shared a variety of images of a new Apple Watch Leather Loop with 9to5Mac earlier this month, and now similar images have surfaced on Reddit.

Apple currently sells the Leather Loop for Apple Watch in four different colors: peacock, Meyer lemon, saddle brown, and black.

The Apple Watch Leather Loop shown in the leaked images certainly looks to be more sporty.

As of right now, it’s unclear when Apple might unveil the new Leather Loop for Apple Watch, and it’s possible that plans are scrapped.

Build-to-order Macs (BTO) are finally available in India through Apple Authorized Resellers.

Customers in India, a key overseas market for American technology giants, have long requested this feature, which Apple offers in several regions.

Prior to this, Apple only offered select variants of its Mac computers in India and gave no option to customers to ask for specific upgrades.

“Previously, there was no real way to get a built-to-order or configure-to-order Mac in India.

Currently, Apple has a website in India, but as soon as you click a Buy button you are directed to authorized resellers.

The original lawsuit alleged owners of social media platforms are capable of regulating free speech, and do so at the peril of conservative voices.

Loomer, who has a long history of publicly voicing anti-Muslim sentiment, also claimed Google engaged in a conspiracy to stifle growth of the Freedom Watch YouTube channel.

"The Plaintiffs do not show how the Platforms' alleged conduct may fairly be treated as actions taken by the government itself," McFadden writes.

Apple's involvement in the alleged conspiracy is not detailed, though the Freedom Watch podcast was available on the Apple Podcasts platform in 2018.

Apple has reportedly won rights to "Killers Of The Flower Moon," a high-profile and hotly contested film directed by Martin Scorsese, starring Leonardo DiCaprio and Robert De Niro.

Under terms of the agreement "Killers of the Flower Moon" will be streamed as an Apple original film, with Paramount set to distribute in theaters.

To capitalize on the feature, Paramount will debut the film in theaters prior to streaming on Apple TV+, the report said.

Imperative Entertainment paid $5 million for rights to the book.

"Killers Of The Flower Moon" marks the first significant pairing of DiCaprio and DeNiro since "This Boy's Life."

Photos of a prototype third-generation iPod touch in a private collection surfaced on Twitter Wednesday, showing off a design with a centered rear camera that never made it to production.

Giulio Zompetti, a developer who collects Apple prototypes, shared new images of a device in his collection: a prototype iPod touch with a rear-facing camera.

The "iPod touch 3" did not come equipped with a rear-facing camera, but leaked images of apparent prototype devices illustrate that Apple was exploring the possibility.

Notably, the LiDAR module is located below the camera array and is not integrated into the hump area as on iPad Pro.

In a follow-up tweet, Fudge claims "iPhone 13" will feature a 64-megapixel shooter with wide lens and 1x optical zoom (6x digital zoom), 40MP telephoto lenser with 3x to 5x optical zoom (15-20x digital zoom), 40MP ultra-wide with 0.25x "optical reverse zoom" and a 40MP anamorphic lens sporting a 2.1:1 ratio.

Photographs of a purportedly redesigned Leather Loop band — or completely new leather strap — for Apple Watch were posted online on Wednesday, with an accompanying report suggesting Apple could introduce the accessory in June.

Posted to Reddit, the images show what appears to be a newly styled Leather Loop band with more prominent ribbing, magnetic closure and new color options.

Unlike the current Leather Loop accessory, the rumored update seems to rely solely on magnets to affix two leather strips around a user's wrist.

Further deviating from the Leather Loop are bumps or cushions that sit atop a flat leather tongue.

The current Leather Loop is reserved for larger 44mm Apple Watch models.

Adding to a mounting number of artificial intelligence-related acquisitions, Apple in the past few weeks purchased Ontario-based Inductiv to work on Siri and machine learning initiatives.

Hours after HBO launched its long-awaited HBO Max app on iOS, Apple TV and other platforms on Wednesday, the AT&T-owned company has pulled streaming integration with Apple TV Channels.

One of the first major cable networks to sign on to Apple TV Channels, HBO is no longer available to new users accessing Apple's collaborative streaming hub.

Existing customers who signed up for HBO's streaming service through Apple TV Channels will retain access to the provider's content through the TV app.

Those who subscribed through Channels can, however, use their Apple ID to authenticate the new, and more expansive, HBO Max app which debuted today.

Apple on Wednesday ceased code signing for iOS 13.4.1, restricting users who upgraded to the latest version of iOS, iOS 13.5, from downgrading to the now-outdated variant.

The halt to iOS 13.3.1 signing arrives exactly one week after iOS 13.5 was issued to iPhone users on May 20.

As with previous stoppages, users can no longer download the previous iOS 13.4.1 version from Apple's servers.

The new iOS 13.5 release delivers a number of features related to the ongoing coronavirus pandemic, including an official launch of the Apple-Google Exposure Notification system.

mock ( false ) ) } }The beauty of the fact that Xcode previews are declared using normal Swift code is that it lets us write our own utilities and abstractions, that in turn can let us use previews in much more powerful ways.

One way is to embed our ReminderRow component in a platform-provided container, such as a NavigationView , before previewing it.

Just like standard SwiftUI views, multiple preview views can be grouped into a single container using the Group API.

Whether you’ve been using Xcode Previews since the first beta of Xcode 11, or whether they’re completely new to you, I hope that this article has showed you at least one new way of using them.

For example, here we’re now using a private makeNameLabel method to create and setup the UILabel for our nameLabel property:class BookViewController: UIViewController { private lazy var nameLabel = makeNameLabel () private lazy var authorLabel = UILabel () override func viewDidLoad() { super .

But we can also define static properties — ones that are attached to a type itself, rather than to instances of it.

We can now use the above date formatter whenever we want to convert a Book -related date into a string, or vice versa:let string = Book .

When I set out to build this latest version of Swift by Sundell, I knew that I wanted to stay as far away from those ugly parts of the modern web as possible.

So, when I set out to build Swift by Sundell 2.0, I expanded that idea of building a website using a basic set of technologies into somewhat of a personal engineering challenge.

So the reason Swift by Sundell doesn’t use any client-side JavaScript is not because I hate the language.

But if that’s not the case, then there’s no shame in using JavaScript either.

And if you prefer building websites using JavaScript, or any other language, then that’s of course fine too.

Kyle Lee, also known as Kilo Loco, joins John to go behind the scenes of Publish — the static site generator used to build Swift by Sundell.

Their support helps me keep the website, and this RSS feed, free and open to everyone.

Loca Studio is a fast, native Mac app that can help you detect common mistakes within your localization files, help you find the right format strings to use, and much more.

As an example, Loca Studio will validate strings referring to system features (such as the name of the Settings app, or other operating system terms), and will warn you if any of your app’s translations seem incorrect.

Today marks exactly three years since I started Swift by Sundell, and while I’m incredibly happy with how this project has evolved and grown during those past three years, the incredible journey that this project has taken me on wasn’t something that I ever could have planned (or honestly even imagined).

When I first launched this website on the 5th of May 2017, I did it for a simple reason: I wanted to write about Swift.

I didn’t intend for this website to become my full-time job, but I’m really glad that it did.

That protocol-oriented design also enables us to use protocols in many different ways within our own code as well — all of which can essentially be divided into four main categories.

This week, let’s go through those categories, and both take a look at how Apple uses protocols within their frameworks, and how we can define our own protocols in a very similar fashion.

Let’s start by stepping out of category number one, and explore a few different ways of defining protocols in Swift.

Category number two is for protocols that are used to define formal requirements for a given kind of object or API.

Do you agree with my way of splitting Swift’s various protocols up into those four categ…

.navigationBarTitle("Navigation") }Notice how the navigationBarTitle() modifier belongs to the text view, not to the navigation view?

You see, navigation views let us display new screens of content by sliding them in from the right edge.

Tip: You can use navigationBarTitle() on any view inside the navigation view; it doesn’t need to be the outermost one.

Like navigationBarTitle() , both of these are modifiers are attached to a view inside your navigation vi…

In this article we’re going to look at how you can build neumorphic designs using SwiftUI, why you might want to, and – most importantly – how we can modify those designs to be more accessible.

Building a neumorphic cardThe simplest starting point is to build a neumorphic card: a rounded rectangle that will contain some information.

We’ve only written a handful of lines of code, but already we have a neumorphic card – I hope you’ll agree SwiftUI makes it surprisingly easy!

Let’s explore this by creating a custom button style, which is how SwiftUI lets us share button configurations in many places.

That’s a lot, but let me break it down:Our base circle is the neumorphic effect circle we have…

Update: Cory Benfield from Apple has confirmed that on Apple's platforms SwiftCrypto is limited to those that support CryptoKit, and can't act as a polyfill for older releases such as iOS 11/iOS 12 and macOS 10.14.

In theory that could mean we get SwiftCrypto support for iOS 12 and earlier, which would be awesome!

Apple today released SwiftCrypto, an open-source implementation of the CryptoKit framework that shipped in iOS 13 and macOS Catalina, allowing us to use the same APIs for encryption and hashing on Linux.

Even better, Apple states that the “vast majority of the SwiftCrypto code is intended to remain in lockstep with the current version of Apple CryptoKit,” which means it’s easy for…

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.

Remember, we're effectively telling SwiftUI the old list has gone away and there's a new list now, which means it won't try to move rows around in an animated way.

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.

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.

For example, CILinearGradient has two points and two colors, while CIBarsSwipeTransition has an angle, a width, and a bar offset.

Start by adding an import to bring in all the new types:import CoreImag…

If you’re completely new to Swift and iOS development (or need a brush-up), this is the series for you.

The iOS Apprentice is a series of epic-length tutorials for beginners where you’ll learn how to build four complete apps from scratch.

If you’re new to iOS and Swift, or to programming in general, learning how to write an app can seem incredibly overwhelming.

The iOS Apprentice series doesn’t cover every single feature of iOS – it just focuses on the absolutely essential ones that you need to know.

Instead of just covering a list of features, the iOS Apprentice series does something much more important: it explains how all the different building blocks fit together and what is involved in…

Get started with Machine Learning for Apple and iOS!

The truth is, you don't need a PhD from a prestigious university or a background in mathematics to do machine learning.

If you already know how to code, you can pick up machine learning quite easily — promise!

The first bit is a gentle introduction to the world of machine learning and what it has to offer — as well as what its limitations are.

Even better, you'll learn how machine learning works behind the scenes — and why this technology is awesome.

April is the month when apple trees start to bloom up here in the Pacific Northwest.

Like the Fuji and Gala varieties that predominate in this region, most apple cultivars are self-unfruitful — which is to say that they require cross-pollination to produce a good crop consistently.

But even they would typically benefit from cross-pollination.

For many years, the dance language of the bumblebee eluded all those who studied it.

That is until a mathematician named Barbara Shipman made the connection between a bee’s dance language and the six-dimensional geometry of flag manifolds, of all things.

We’re hearing a lot about contact tracing these days, but the technique has been used for decades.

With over a million confirmed cases of COVID-19 worldwide, many regions are well past the point where contact tracing is practical.

$ uuidgen 33F1C4D5-3F1C-4FF0-A05E-A267FAB237CBEvery 24 hours, the device takes the Tracing Key and the day number (0, 1, 2, …) and uses HKDF to derive a 16-byte Daily Tracing Key Temporary Exposure Key .

Apple and Google’s Contact Tracing standard defines a new Contact Detection service.

In the first version of Contact Tracing , all you could learn about a positive match was how long you were exposed (in 5 minute increments) and when contact occurred (with an unsp…

This week on NSHipster, we’re taking a look at Swift Log : a community-driven, open-source standard for logging in Swift.

Adopting SwiftLog in Your Swift ProgramAdding Swift Log to an existing Swift package is a breeze.

Process Info import Logging import Logging Syslog import Logging Slack Logging System .

public struct Git Hub Actions Log Handler : Log Handler { private var output Stream : Text Output Stream internal init ( output Stream : Text Output Stream ) { self .

output Stream = output Stream } … }Then, in the test target, create a type that adopts Text Output Stream and collects logged messages to a stored property for later inspection.

Xcode build configuration files, more commonly known by their xcconfig file extension, allow build settings for your app to be declared and managed without Xcode.

But there’s more to Xcode build configuration files than meets the eye.

But you might use this as a hook for optional development tools like Reveal, which requires the following configuration: # Reveal.xcconfig OTHER_LDFLAGS = $( inherited ) -weak_framework Reveal Server FRAMEWORK_SEARCH_PATHS = $( inherited ) /Applications/Reveal.app/Contents/Shared Support/i OS-LibrariesCreating Build Configuration FilesTo create a build configuration file, select the “File > New File…” menu item ( ⌘ N ), scroll down to the section labeled “Othe…

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.

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

( raw Value : cmark_node_type ) { switch raw Value { case CMARK_NODE_DOCUMENT : self = .

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…

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.

Thanks to Swift’s support for Language Server Protocol, we’ll soon be able to edit Swift code — syntax highlighting, autocompletion, and all — directly from the browser.

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.

One important aspect of this is accessibility: ideally, my progress view should be indistinguishable from a system progress view to VoiceOver users.

Accessibility properties in unit testsTo this end, I’d like to write a unit test that fails when it finds a discrepancy between my view’s accessibility settings and those of a standard UIProgressView .

class UIAccessibilityTests : XCTestCase { func testUIProgressViewAccessibility () { let progressView = UIProgressView () progressView .

In a unit test target for an iOS application, only the first assertion ( isAccessibilityElement ) fails, the others pass.

RequirementsTo summarize, the requirements for testing UIKit’s accessibility properties in…

Running the Docker containerFirst, download, install, and run Docker Desktop for Mac.

Older Swift versions To test on older Swift versions, replace swift:latest with a different tag, e.g.

The Docker Hub page for the official Swift image lists all available tags for released Swift versions.

Prerelease Swift versions Recently, the Swift CI team has also begun to publish nightly Swift builds to Docker.

For alternative approaches, check out my 2017 post on how to run Swift packages in Docker.

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

How to test your SwiftPM package on Linux from macOSCheck out Testing Swift packages on Linux using Docker.

Adopting automatic test discoveryI found two open bugs (SR-11951 and SR-12008) that suggest that the test discovery doesn’t work correctly with certain test case setups.

You should confirm that the automatic test discovery finds all test methods in your package.

Diffing the outputs of swift test --list-tests and swift test --enable-test-discovery --list-tests should not show any differences.

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 …

Предлагаю вам план супер-продуктивного карантина на следующую неделю: - В понедельник, 25 мая, слушаете доклад про сравнение современных архитектурных паттернов: что в тренде, а что давно пора закопать?

- Во вторник присутствуете на показательном собеседовании: никакой постановки, именно так проводят архитектурную сессию в крупнейшую российскую продуктовую компанию. Учиться на чужих ошибках — идеальный способ подготовиться к собесу!

- В среду и четверг засыпаете острыми вопросами экспертов на интервью о том, как у них там все устроено. Ведь самое интересное — это не то, какую архитектуру используют в очень_крупной_компании, а то, как разработчики ее адаптируют под свои нужды и с какими труд…

We all like debugging menus in apps, it simplifies our life a lot in many ways (custom configuration, clear cache, toggling feature flags, and so on), but what about end-users? These are features that we can’t ship to production. To hide this functionality developers often use compiler directives with different configurations, hardcoded userId’s, secret gestures, etc. So an author offers a really good way by using a custom profile that includes a certificate. p.s. try tapping 10 times on "Settings" bar item in telegram... https://andrewking.ca/2020/04/how-to-enable-custom-debugging-in-release-builds/

Interesting compilation of articles about achieving accessible components using the native approaches. An author points out that it's better to avoid simulate a button behaviour adding a UITapGestureRecognizer when you stuck at something in implementation (multi-lines button for example) - may be a similar behaviour already exists? Because in this case, it's easy to forget about users with accessibility problems. So far, there are only articles about UIButton, but he is going to keep it full with other components as well. https://jeffwatkins.dev/articles/building-on-uikit

Swift Foundation is now building on Windows and passing all tests, interop with C++ is being discussed on the forums, and new Swift libraries are available.

We discuss recent news, evolution proposals, and Swift 6

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.

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.
