It turns out that in addition to all known access levels, there's also an experimental feature called SPI (System Programming Interfaces). It lets for library developers shipping experimental features only to dedicated clients and hiding those features to other ones.

FYI 👇

Q: Is there a documentation up for accessing dynamic island (on iPhone 14 Pro) with live activities? Couldn't find anything

A: Live Activities are implemented using the ActivityKit framework, which was available in iOS 16 beta 4 and iOS 16 beta 5. The ActivityKit framework is not included in iOS 16 RC, and is not included in Xcode 14 RC. ActivityKit will be included in an update to iOS 16 coming later this year, as mentioned in this News and Updates post. Once ActivityKit is available in an update to iOS 16, you'll be able to implement Live Activities and interact with them in Dynamic Island.

Turns out that there is a UML generator for Swift. I wish I had known about it last year.

In addition, a small example - how to generate class diagrams from a framework.

Long read about the presentation changes in iOS and iPadOS 16

• When the presenting view controller is in a regular-width environment on iPad, form sheets are slightly bigger than on previous iPadOS versions. This changed in beta 4. (If the presenting view has compact width, a form sheet presentation will adapt and fill the width, just like on iPhone.)

• The height of the navigation bar in a non-full-screen, non-popover, modally-presented view controller is smaller than before (12 points smaller on iPhone and 6 points smaller on iPad), but this has not (yet?) changed in SwiftUI. This change has only just occurred in beta 5.

• Non-full-screen modally-presented double and triple column style split view controllers have a different appearance compared to iPadOS 13 to 15.

Xcode 13.3 is finally here.

Some of the features I’m happy to see:
- Xcode can now build documentation from your Swift code in executable targets, like apps and command-line tools.
- The build system and Swift compiler have a new mode that better utilizes available cores, resulting in faster builds for Swift projects (need to enable it manually)
- Swift Packages now support build tool plugins. This allows packages to define plugins that can specify tools that should run during a build operation, for example to generate source code.
- You can now write inverted availability conditions using the new #unavailable keyword
- ... more Swift 5.6 feature

As DoсC gains popularity these days, we may see more great articles on that subject. It's also worth mentioning that Xcode 13.3 will allow writing documentation even for usual apps, not only for packages. Starting with Swift 5.6, it adds the official support for transferring docs to static hosting options, such as Github Pages, which the author talks about in this article.

There're many excellent articles about TaskGroup, but most of them cover some common scenarios. Marin, the author of Modern Concurrency in Swift prepared a more detailed post by revisiting his slides from iOS Conf SG 2022.

A bit of new API: layout guide that is useful for full-screen content:
safeAreaAspectFitLayoutGuide

“Unlike the standard rectangular safe area defined by the safeAreaLayoutGuide/safeAreaInsets, this new layout guide API considers the true shape of the safe area, including the curvature of the display edges and sensor housing/island areas, maximizing the content without clipping.”

Read the Tyler’s thread about the all details.

Thomas discusses about AttributedString in SwiftUI: what is good, what is bad, what would be great to improve. He also prepared a helper that simplifies the life when working with texts.

p.s. now it's a little confusing when dealing with attributed strings. I really hope that Apple will take this problem into account and improve it soon. But this "soon" isn't really soon for us, unless you only support the latest version. 🥲

Discovered something great today I want to share with you! How many times defining a custom decodable initializer, for instance, have you lost the ability to use the automatically generated memberwise initialize, umm? Oh, I've faced it so often, especially in tests. So the solution is easy - just define this initializer in an extension, and that's it.

As you all know, Apple presented their own CI/CD system at last WWDC - Xcode Cloud. While it's still in beta, a developer can submit an access request to play around though.

To simplify this process an author prepared two articles (so far):
- how to enable Xcode Cloud, test and distribute apps
- more advanced article about the use of custom build scripts and environment variables.

If you're already familiar with Xcode Cloud, just skip the first post and dive into the second one. I'm sure this will help you to avoid some of the non-obvious pitfalls and save your time.

Haven't posted for a while something interesting about build time optimization, so here it is.

The article describes the various aspects:
- collecting the build data from developer machines by XCLogParser
- analyzing the compilation process using Swift compiler flags
- getting and interpreting build.trace files by using New Build System tricks
- and of course, the possible solutions
