Recently I posted about publishing a DoсC documentation as a static website. But with Swift 5.6 there's a Swift DoсС Plugin that simplifies this process a little more.

Really interesting dive into how containers such as List, Stacks work under the hood using Variadic­View to modify individual children. A nice addition that you can use the same approach for build your own containers.

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

Apple now lets developers configure custom offer codes in App Store Connect.

Offer codes can be used in a variety of ways:
- Send an email sharing the latest features and recently added content with an offer code to current or lapsed subscribers, so they can experience your service for a limited time.
- Distribute flyers that include custom codes to promote your service to event attendees.
- Partner with another company on a marketing initiative or referral campaign to help promote your app.
- Provide a code to a subscriber with a customer service issue to compensate for the issue and encourage retention.
- Distribute one-time-use codes within an app that you’re sunsetting as a way to transition current subscribers to your new app and promote your service.

Oh, what a surprise!

“Use switches in table rows only. Switches are intended for use in tables, such as in a list of settings that can be toggled on and off. If you need similar functionality in a toolbar or navigation bar, use a button instead, and provide two distinct icons that communicate the states.”

May your code always compile on the first try, found bugs are features actually and all projects start with iOS 15.

If you are looking forward to adopting new concurrence features in Xcode 13.2, don’t install Xcode from AppStore.

To workaround this issue, please re-download Xcode 13.2 directly from Releases section.

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.

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. So if you know the basics of TaskGroup, this fictional example will surely improve your concurrency skills.

Apparently only I've not written about the new Swift Playground for iPads yet...

TL;DR

- Yes, you can now build SwiftUI apps right on your iPad.
- Yes, you can use also UIKit if you prefer.
- Yes, you can ship your apps to the App Store straight from your iPad.
- Yes, it supports Swift Package Manager packages from GitHub.
- Yes, you get the fantastic new code completion, just like with Xcode.
- Yes, it ships with Swift 5.5 and all the concurrency awesomeness that entails.

FYI, be careful!

«In iOS 15 and later, the system may, depending on device conditions, prewarm your app — launch nonrunning application processes to reduce the amount of time the user waits before the app is usable. Prewarming executes an app’s launch sequence up until, but not including, when main() calls UIApplicationMain. This provides the system with an opportunity to build and cache any low-level structures it requires in anticipation of a full launch.

If your app executes code before the call to UIApplicationMain, such as in static initializers like load(), don’t make assumptions about what services and resources are available. For example, keychain items may be unavailable because their data protection policies require an unlocked device and prewarming happens even when the device is in a locked state.»

UPD
Seems like a bug, but application(_:didFinishLaunchingWithOptions:) is invoked as well during a prewarning. I've sent a link to a thread in the comments. 🤔
