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.

Look at the image - familiar situation? Just a typo. The code compiles and then crashes at runtime. An author found a halfway solution for detecting these problems, but only for custom view modifiers - using a special Swift attribute. So at least we can make our code safer.

Uh, looks like I haven't posted much about SwiftUI, so let's fix it! An author prepared a comprehensive step-by-step tutorial about building an animated circled checkmark from scratch. If you're not confident about this topic or maybe it's new for you at all, it will be interesting reading by far.

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.

Some of the interesting highlights from the new Xcode:

- Finally! Simplify an app icon with a single 1024x1024 image that is automatically resized for its target. Choose the Single Size option in the app icon’s Attributes inspector in the asset catalog. You can still override individual sizes with the All Sizes option. 🎉
- Starting with Xcode 14, bitcode is no longer required for watchOS and tvOS applications, and the App Store no longer accepts bitcode submissions from Xcode 14. 🤷‍♂️
- Instruments now includes a new Swift Concurrency template for tracing the usage and behavior of Swift’s concurrency primitives.
- Instruments has a new Hang Tracing instrument that shows when an app’s main thread is unable to handle incoming events for an extended period of time, potentially causing the UI to hang.
- Hang reports in the Xcode Organizer provide diagnostic reports on application hangs to assist in improving responsiveness. Reports are generated for an individual app release and ordered by severity. They include sample logs for hangs occurring on the main thread that you can use for debugging as well as statistics on affected devices and iOS versions for the report.
- Xcode Previews can now run on physical devices without requiring a containing application, making it easy to preview on-device for frameworks and Swift packages.
- Added a refactor action to add an explicit Codable implementation.
- Simulator now supports remote notifications in iOS 16 when running in macOS 13 on Mac computers with Apple silicon or T2 processors. Simulator supports the Apple Push Notification Service Sandbox environment. Your server can send a remote notification to your app running in that simulator by connecting to the APNS Sandbox. 💃
- Xcode now pins elements of your code structure to the top of the editor as you scroll through a document.
- Swift 5.7 with a lot of new features!

I think a lot of developers are stressed when dealing with the iOS signing process, and that's fine. Therefore, Bruno has prepared a short article to refresh the knowledge for these people.

Over the years iOS comes with new API developers want to adopt and it'd be very tempting to support only the latest OS, but the reality is different. So I'm sure you can find many availability labels for back-deploy features in your codebase… But what if we don't need these shims anymore - we need to remember to get rid of them all on every OS upgrade? Wouldn't it be cool to delegate it to the compiler, would it? So Dave's prepared an interesting solution, let's read it!

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.”
