For precise control over which attributes should animate in #SwiftUI, especially in generic components that accept arbitrary content, we can use the animation(_:body:) API introduced in iOS 17 to avoid accidental animations. I've written a post about it: nilcoalescing.com/blog/Isolate...

Last week I had an amazing opportunity to be part of the ARCtic Conference and present a talk on lesser known Swift language features. I really enjoyed the conference and my stay in Lapland ❄️ ☃️ 🦌 Thank you to all the organizers, speakers and attendees!

Using @Observable is great, but it has one small caveat. The initializer of the @Observable objects will be called multiple times, even with @State @nilcoalescing.com's excellent article covers that topic in more detail. #iOS #swiftUi nilcoalescing.com/blog/Initial...
