Still unable. visionOS 1.0 Simulator is installed as a platform, but I can't select it as a run destination or add it to a target as a supported destination.

Watch https://developer.apple.com/system-status/ for resolution.

Still not working in the U.S. Sigh...

This situation has gotten even worse in iOS 14.3. The only reliable solution I've found is to abandon .onAppear/.onDisappear, use a @State var to track TabView transitions with .onChange, AND debounce calls to .onChange which can occur one or more times. See: [https://stackoverflow.com/questions/64641759/swiftui-pagetabview-in-ios14-2-will-recall-childview-onappear-method-many-times/65542867#65542867)]

The simplest solution to issue #1 is to place your views (10 or less) into Groups, e.g.: Group { Text("Hello, World! 1 ") Text("Hello, World! 2 ") Text("Hello, World! 3 ") Text("Hello, World! 4 ") Text("Hello, World! 5 ") Text("Hello, World! 6 ") Text("Hello, World! 7 ") Text("Hello, World! 8 ") Text("Hello, World! 9 ") Text("Hello, World! 10 ") } Group { Text("Hello World! 11 ") ... }

The solution posted by TripleMonkey worked for me. No need to delete derived data or change the GPU selection. Thanks!

This is limited to the App Store version. Download Xcode from https://developer.apple.com/download/more/ to regain access to the developer documentation.

The developer documentation issue is limited to the App Store version of Xcode. Download directly from https://developer.apple.com/download/more/ to regain access to documentation. This does not solve the Spotlight crash.

Same, and solved with the non-App Store version. Both show build as 12A7209, but the App Store version shows a Created date of Aug 25 vs Sept 9.
