Apple designed WKWebView in 2014 to ensure that you can integrate web content into your app quickly, securely, and consistently across iOS and macOS.

Since then, we’ve recommended that you adopt WKWebView instead of UIWebView and WebView — both of which were formally deprecated.

New apps containing these frameworks are no longer accepted by the App Store.

And last year, we announced that the App Store will no longer accept app updates containing UIWebView as of December 2020.

However, to provide additional time for you to adopt WKWebView and to ensure that it supports the features most often requested by developers, this deadline for app updates has been extended beyond the end of 2020.

Now it’s simpler than ever for developers based in the United Kingdom and Ireland to enroll in the Apple Developer Program.

The Apple Developer app now supports enrollment in these regions, allowing developers to start and finish their membership purchase with local payment methods on iPhone or iPad.

And since membership is provided as an auto-renewable subscription, keeping it active is easy.

Introducing Swift Cluster Membership August 27, 2020 Konrad Malawski is a member of a team developing foundational server-side Swift libraries at Apple, with focus on distributed systems and concurrency.

It is my pleasure to announce a new open source project for the Swift Server ecosystem, Swift Cluster Membership.

Providing a predictable, reliable answer to this question is what cluster membership protocols do.

Therefore, the "Pattern Consistency" section of the original proposal has been removed, and replaced with a [ "Disambiguating pattern matches" section ](https://github.com/apple/swift-evolution/blob/aecced4919ab297f343dafd7235d392d8b859839/proposals/0155-normalize-enum-case-representation.md), which…

Statements that introduce limited available contexts, such as `if #available(...)` , allow use of newer APIs while still making the code backward-deployable to older versions of the libraries.

A function builder carries complete type information (such as SwiftUI's [ `ViewBuilder` ](https://developer.apple.com/documentation/swiftui/viewbuilder)) may need to "erase" type information from a limited availability context using `buildLimitedAvailability` .

Here is a SwiftUI example borrowed from [ Paul Hudson ](https://www.hackingwithswift.com/quick-start/swiftui/how-to-lazy-load-views-using-lazyvstack-and-lazyhstack):Statements that introduce limited availability contexts, such as `if #available…

Hi everyone, i finished the Angela Yu course and now i'm trying to improve with some more advanced topics. I'm following the iOS Dev Academy tutorial on Youtube about coding a Messenger chat app. In this chapter of the tutorial he is setting up a Firebase Realtime DB, then he is storing the account credentials in the DB when the user is prompted to register. Before doing so he wants to check if the associated email used for the registration already exists inside the DB, and if it exists he wants to show an alert to the user asking him to change email. By code, here's the issue. The first snippet is from the RegisterViewController, the second from DatabaseManager file. In the completion of t…

So I have a project to do where I must make an app for mobile devices, preferably both iOS and Android ones. But what should I use to do this?

Any advice for what I should be doing to get started on it? submitted by /u/Sargent379 [link] [comments]

There is definitely not a straightforward answer to this question. I'd like to ascertain a rough estimate of how long it would take, in hours, to build a relatively simple social app assuming the wireframes/designs are already completed. The app would have 4-5 core screens. Functionality would include content sharing, users/profiles, chat capabilities, and push notifications. submitted by /u/wheredidspringgo [link] [comments]

So everytime a premium user posts something, other users will see a "Plus" or "Professional" tag next to the user's name.

I have 2 same applications with the same marketing budget. Google play app gets 5-10 reviews daily while Apple app store app gets only 0 or 1 review in a week. The number of ratings is similar on the app store and play store. Only reviews are so few. We show the typical rate us popup on the same place and frequency on both apps. It might be because of the UX of play store rate us popup leading people to review in the app without leaving the app while apple leads to users to app store page so they have to leave the app. How to increase IOS reviews? submitted by /u/rdvn [link] [comments]

Six months is easily enough time to build and test a simple app, so technically you could start accepting pre-orders before seriously starting development.

Note: Please don't do this!

I'm only kidding!

This is great news if you're struggling to meet the December deadline for migrating away from UIWebView.

Before you completely abandon your migration plans though, I'm pretty sure this will still happen, so it'd be wise to continue working on it.

I knew this would be a tricky one.

You'll find lots of advice on the internet to run pricing experiments with your products (whether it's an app, or anything else) but implementing them takes time, effort and persistence over a long period.

An analyst with an excellent Apple track record estimates that the company last month achieved a milestone of a billion iPhones in active use.

According to my estimate, Apple passed the billion iPhone users milestone last month.

There had been speculation that Apple’s 2018 decision to stop reporting unit sales was because iPhone sales had peaked.

Flat to down iPhone unit sales do not automatically mean iPhone business fundamentals have deteriorated.

For FY2020, iPhone sales to new users will likely have accounted for less than 20% of overall iPhone sales – an all-time low.

As it nears an estimated 50% adoption rate, Apple's iOS 14 update is poised to overtake iOS 13 as the most installed version of the mobile operating system.

Although Apple hasn't released official iOS 14 adoption numbers yet, Mixpanel's iOS 14 adoption data indicates that the update is installed on 46.36% of compatible devices.

It also appears that adoption of iOS 14 and iPadOS 14 initially outpaced Apple's previous update, reaching 26.81% of active iPhone, iPad and iPod touch users just five days after launch.

In 2019, iOS 13 hit 20% adoption in that same timeframe.

Since its debut in September, iOS 14's adoption rate has seemingly slowed and is now lagging slightly behind where iOS 13 was…

A new listing for an Apple "personal computer" has surfaced in a Bluetooth product database, potentially revealing an unreleased Mac or iPad.

The device listing carries a placeholder name of B2002 and is listed under the "personal computer" category.

Without a model number, it's also impossible to tell whether the device is actually a released product like the recently refreshed iPad Air model.

The listing is Apple's first in the Bluetooth product database since 2019.

That's likely because Apple is able to update previous listings for device refreshes if they use the same or similar specifications.

Long-time "Daily Show" host Jon Stewart is set to return to his beat, in a long-term deal for Apple TV+.

Stewart is said to deliver "hourlong, single-subject episodes" with Stewart as the host and executive producer.

Also attached to the show is former HBO head Richard Plepler, who has an existing deal with Apple through Eden Productions.

Stewart is not new to the executive producer role.

Stewart has produced "The Colbert Report," " The Late Show with Stephen Colbert," as well as two films.

Earlier in 2020, Apple reportedly purchased Barcelona startup Vilynx that specialized in artificial intelligence, machine learning, and computer vision.

Citing sources familiar with the matter, a report on Tuesday claims that the Barcelona, Spain based startup was purchased to enhance Apple's artificial intelligence work as a whole.

A mission statement about the company says that the company can "add rich metadata to enable search and social sharing."

The company also claims that the metadata makes convent instantly discoverable.

The CrunchBase profile of the company was recently updated to reflect that the company is now in Palo Alto, California.

In the midst of a changing relationship with Apple, Foxconn has sometimes resorted to methods like exaggerating hiring counts to cut costs and boost margins.

Foxconn's gross profit margins are in the single-digit percentage points, while Apple's are about 40%.

The equipment was then shipped back before Apple carried out an audit of Foxconn's production lines.

According to former Apple and Foxconn staffers, the practice became harder when Apple started attaching tracking tags to its equipment.

This image of a changing and strained relationship between Apple and Foxconn has manifested in other ways.

The Apple Car could have an intelligent active suspension system, one that includes a way to store and maintain a level of pressure in a hydraulic system to enhance the ride of the car for drivers and passengers.

Some cars use a form of active suspension system that provide more control over the position of wheels in relation to the chassis, which can perform a better job at minimizing corner roll and road bumpiness.

While most cars still employ a form of passive suspension system that uses springs and shock absorbers, active suspensions tend to be used in higher-priced vehicles.

In the patent titled "Active suspension system with energy storage device," Apple describes a fairly typical hyd…

SK Telecom is opening "T Factory," an unmanned 24-hour, where it claims partnerships with Apple, Microsoft, and more, mean customers will be able to buy an iPhone in under five minutes.

One of Apple's 5G carrier partners for the iPhone 12 in South Korea, SK Telecom, has announced the opening of "T Factory" on October 31.

Based in Seoul, the store is designed to showcase the devices of SK Telecom's partner companies, such as Apple, and Microsoft.

The self check-in includes a thermal sensors to protect against the coronavirus.

Backbone Labs has launched Backbone One, a game controller for iPhone that, used with its companion app, aims to make mobile gaming closer to its console counterparts.

Quietly launched on Tuesday, Backbone consists of two components, consisting of the controller itself and a companion app.

The controller is currently only available to purchase through the companion app, offered in limited "drops" to consumers, rather than through traditional retailers.

The controller also has four other buttons, which all take advantage of the companion Backbone app's various functions, which aims to elevate the mobile gaming platform to one closer to console gaming.

The controller is compatible with the iP…

The first, TVision Live, features live sports and news and starts at $40 a month.

Other tiers including a $50-a-month TVision Live TV+ option with more than 10 additional channels, and a TVision Live Zone with additional live sports channels.

It's an a la carte streaming service platform similar to Apple TV Channels.

The carrier is also launching its TV service with a special Apple-related promotion.

Customers who sign up for TVision Live TV+ or Live Zone by Dec. 31 will get a free year of Apple TV+, with the option to add an Apple TV 4K for $99.

The upcoming Apple TV+ series follows two friends as they attempt to mend a friendship after falling out.

The 10-episode series will explore the inner workings of a platonic friendship between two childhood friends who reconnect as adults.

"Platonic" stars Emmy and Golden Globe nominees Rose Byrne ("Damages") and Seth Rogen ("Funny People") as the leads.

Byrne, Rogen, and Conner Welch will executive produce.

The series will be produced for Apple TV+ by Sony Pictures Television.

Linksys is expanding its Wi-Fi 6 lineup of Velop mesh routers, making them more affordable as the number of Wi-Fi 6-capable devices continues to grow.

The Velop AX4200 Wi-Fi 6 mesh system joins Linksys's MX5 Wi-Fi 6 router but comes in at a lower price to make it much more approachable while offering many of the same features.

This Velop router supports 802.11 AX, also known as Wi-Fi 6, and is powered by a 1.4GHz quad-core processor with 512MB of RAM.

Linksys says that the new Velop AX4200 covers 2,700 square feet per node.

At the moment, the Velop AX4200 does not have HomeKit support but Linksys says this is coming in a future update.

A new estimate claims that the number of current, active, iPhone users passed one billion in September 2020, fewer than 5,000 days since the first one went on sale.

But according to Above Avalon, Apple got to one billion active iPhone users at some point in September 2020.

That's one reason it's been hard to be sure when Apple passed not just a billion sold, but a billion in active use.

"Last week we passed another major milestone when we sold the billionth iPhone," Cook said at the time.

Even looking at that alone, though, raises issues of how a billion active users affect the whole of Apple.

Apple's new 2020 iPad Air is on sale right now for $559 at B&H Photo, with the electronics retailer matching the lowest price ever on the iPad Air 4 period — and the best deal we've seen on the brand-new green finish.

New iPad Air 4 priceApple deals are hitting a fever pitch as retailers issue aggressive price drops on even brand-new hardware heading into Black Friday.

Amazon started the price war on the brand-new iPad Air, but quickly sold out, with units back to MSRP.

If you'd prefer the tablet in Rose Gold, Walmart is also running a $40 off promo on the 64GB Wi-Fi Air.

See how these deals stack up to other retailers in our iPad Air 4 Price Guide.

Apple has rolled out an update to Apple Music on Android, one that adds enhanced sharing options as well as Autoplay and changes to search, along with a feature that hasn't yet arrived on iOS - Crossfade.

Updated on Monday, version 3.4 of Apple Music on Android includes a number of changes that brings it largely in line with iOS 14's iteration.

As part of the change, the app has been given a makeover, complete with features the iOS version has offered for the last month.

The Autoplay feature also makes the transition to Android, with users able to let Apple Music select the next songs to play once a playlist has been exhausted.

When enabled, Apple Music will analyze the playlist and select …

A rare phone-hacking circuit board created by Steve Wozniak and marketed by Steve Jobs will go up for auction with a starting bid of $8,000 to $12,000.

The "blue box" populated circuit board was used by so-called "phone phreakers" to hack phone systems and get free phone service.

Although "blue boxes" have been used since the 1950s, Wozniak developed the first digital ones in 1972.

Wozniak and Jobs marketed the "blue boxes" throughout Berkeley and all of California in 1972 and 1973, selling them under the "phone phreaker" monikers of "Berkeley Blue" (Wozniak) and "Oaf Tobar" (Jobs).

I still think it was incredible," Wozniak said of the blue boxes in his biography.

Thanks a lot to RevenueCat for sponsoring Swift by Sundell last week.

Their continued support helps me keep the entire site free and available to everyone in the Swift community.

That’s why I recommend checking out RevenueCat, because they’ll handle all of those complexities for you, all through a very simple and elegant Swift API.

RevenueCat also supports other platforms, such as Android, and includes a suite of really powerful features — including analytics, integrations with other services, web hooks, and more.

One way to use extensions is to add new, custom APIs to the various types that ship as part of the system, for example within the Swift standard library.

Extensions are also commonly used as a code organization tool, which is a practice that Swift inherited from its predecessor, Objective-C.

In Swift, we could use that same approach to structure a given type’s APIs based on their access level.

Finally, let’s take a look at how extensions can also be used to specialize generic types and protocols for concrete use cases.

Thanks a lot to the team behind Strings for sponsoring Swift by Sundell this past week.

Their support is helping me keep the website and all of its content free and accessible to everyone.

I’m a big fan of tools that help bridge the gap between the different disciplines that are involved in building a truly great app, and Strings is definitely one of those tools — as it makes it easy to enable copywriters to directly update your app’s localized strings, without requiring them to clone and update the project’s various Xcode files.

So if you’re often getting requests for string changes in tasks, emails, on Slack, or in bug comments — then I can really recommend trying out Strings.…

New in Swift 5.3: Property observers can now be attached to lazy properties, which makes it possible for us to automatically observe when a new value was assigned to a given property, even if its value is lazily loaded when first accessed.

To make sure that the latest value is always persisted, we’ve added a didSet property observer to our controller’s theme property, but before Swift 5.3, we couldn’t then also make that property lazy — meaning that we’d first have to give it a default value when declaring it, and then load its actual underlying value as part of our controller’s initializer, like this:class ThemeController { var theme = Theme .

My thanks to indie developer Matthew Bickham for sponsoring Swift by Sundell last week to promote his Magic Lasso ad blocker.

Now, I realize that advertising an ad blocker might seem a bit strange, but what I really like about Magic Lasso is that it cleans up the web by removing many of the user-hostile ads that are out there, while still keeping completely native ads (like the ones that you’ll find on Swift by Sundell) intact.

Magic Lasso will automatically block things like autoplaying video ads, unwanted popups, banners, privacy-invading trackers, and more — which in turn can make browsing the web using Safari up to two times faster.

When discussing the topic of unit testing and automated tests in general, it’s incredibly common to use the term testable code — code that’s synchronous, predictable, and always produces the same output for a given set of inputs.

host = host.

url else { return nil } var request = URLRequest (url: url) Kind .

Stub , String > let host = URLHost (rawValue: "test" ) func testBasicRequestGeneration() throws { let endpoint = StubbedEndpoint (path: "path" ) let request = endpoint.

To get started, we might write the following implementation, which wraps a UITextView instance in a UIViewRepresentable -conforming struct:struct TextView: UIViewRepresentable { @Binding var text: String func makeUIView(context: Context ) -> UITextView { let view = UITextView () view.

body ) return view } func updateUIView( _ view: UITextView , context: Context ) { view.

text = text } }However, while the above is a great starting point, we’re currently not capturing any edits that the user will make to the above text , since we haven’t connected its Binding to the text view itself.

In this article I’m going to walk through eight common mistakes SwiftUI learners make, and how to fix them.

Some of these mistakes are simple misunderstandings, and with SwiftUI being so big these are easy to make.

Adding views and modifiers where they aren’t neededLet’s start with one of the most common, which is writing more SwiftUI code than you actually need.

For example, we can show an alert whenever selectedUser changes, like this:struct ContentView: View { @State private var selectedUser: User?

Trying to get “behind” your SwiftUI viewOne of the most common problems people hit with SwiftUI is trying to change what’s behind their SwiftUI view.

You’d never get that close to the various senior Apple folks, and although I have a fondness for the McEnery Center it’s never going to come close to Apple Park.

Most previous WWDC talks aimed to be about 40 minutes so they could keep a fixed structure at the venue, but at WWDC20 I watched many that were under 15 minutes.

I’ve also seen various mentions of reshoots to correct errors in the talks where feasible – this happened rarely previously.

My favorite talks from WWDC20I download the WWDC talks because I tend to rewind a lot while watching to make sure I’ve really understood.

There is always one stand out WWDC talk on testing, and this was it for 2020.

Alongside massive improvements to Swift itself (see What's new in Swift 5.3 for more on that), this is a huge leap forward for SwiftUI – we can now make a much wider range of apps.

.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.

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!

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.

We’re happy to announce that UIKit Apprentice (formerly iOS Apprentice) is fully updated for iOS 14 and is available now!

If you’ve been following this site for some time, you’ll know that our flagship book, iOS Apprentice, has launched thousands of people into iOS development ever since it first came out as an epic-length tutorial named “The iOS Apprentice: Getting Started” waaay back in 2011.

With the introduction of SwiftUI, we realized it would be better to keep the focus of our popular iOS Apprentice book on UIKit, and instead write a new, SwiftUI-focused book, SwiftUI Apprentice.

You start at the highest level of abstraction, source code written in a programming language like Swift or Objective-C. That code is parsed into an abstract syntax tree, ( AST ), which is progressively transformed into lower-level, intermediate representations until it finally becomes executable binary.

What if, instead of lowering source code down for the purpose of execution, we raised source code for the purpose of understanding?

Like everything else in 2020, this year’s WWDC had to be a little different if it was going to happen at all.

Attendees of WWDC 1997 could obtain a collection of CDs with video recordings of sessions — a far cry from the VHS tape for WWDC 1990.

And thanks to this more digestible format, we’re starting to see WWDC clips being shared around, which is new and refreshing.

WWDC 2020 was just another week in this bizarre existence amidst this pandemic.

Trivial PursuitI briefly considered reviving the NSHipster Quiz for WWDC 2020, but it didn’t feel right.

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 ) ! }

In Debugging Generics in Swift, Joshua Emmons touches on a tricky area in Swift: the difference between as , as?

When the program is running, the expression 4 in the example has already been assigned the type Int .

As a result, the cast to Double fails because Double and Int are unrelated types (and Swift generally eschews implicit conversions between number types).

The … as Double instructs the compiler to use Double ’s conformance, just like any other implicit or explicit type annotation would.

These two lines are equivalent:let x = 4 as Double let x : Double = 4Ben Cohen:The best way to think of the as keyword is as a way to provide “type context”.

This is a how-to for cleaning up a GPX file by removing unwanted or privacy-sensitive information.

What’s in a GPX file?

We’re gonna use it in one processing step to strip unused namespaces from the GPX file.

ValidationFinally, it’s a good idea to validate the processed GPX file against the official GPX schema:xmlstarlet val --quiet --err --xsd \ http://www.topografix.com/GPX/1/1/gpx.xsd \ output.gpxHappy processing!

Download the (sanitized) GPX file.

Text fragments are a way for web links to specify a word or phrase a browser should highlight on the destination page.

But text fragments have other uses beyond search engines:Linking to a particular sentence or paragraph of a long document.

Browsers could facilitate this by offering to include a text fragment in the URL when sharing a link to a text selection.

Read the text fragments draft spec for details.

This screenshot demonstrates that document.location.hash is blank because Chromium stripped the text fragment away:JavaScript code running in the destination page can’t see the text fragment.

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.

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 () .

sizeCategory ) var sizeCategory var body : some View { VStack ( spacing : 16 ) { Text ( "Root View" ) .

$ isPresentingSheet ) { ChildView () } // …The view that gets presented displays the same data as the root view, without modifying the environment in any way:struct ChildView : View { @Environment (\ .

sizeCategory ) var sizeCategory var body : some View { VStack ( spacing : 16 ) { Text ( "Child View" ) .

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 …

A summary of today’s changes to 3.1.3 Other Purchase Methods:Your app must use Apple’s in-app-purchase (IAP) system for all purchases made in the app.

Unless they’re purchases for goods or services that are consumed outside the app, in which case you are prohibited from using IAP.

Unless you only offer free account creation, in which case, you don’t need to use IAP.

Except for accounts that were created outside the app, which can offer paid account upgrades and don’t need to use IAP.

If you’re selling “experiences” between people, you don’t need to use IAP.

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.

🎉🎉🎉 A few weeks ago, this channel reached 1000 subscribers. Thank you all! I'm really happy seeing a slew number of people here because initially it was created just for saving interesting articles.
