On iOS16, I can't open the audio chart details page via the Audio Graph defined by AXChartDescriptorRepresentable. When trying to open chart details through VoiceOver, the screen flashes for a moment (the content seems to be correct) and then disappears immediately. This behavior was normal on iOS 15, but it doesn't work from iOS 16 beta to RC. I have uploaded the sample project to https://github.com/gongzhang/audio-graph-example. It needs to be running on a physical iOS 16 device with VoiceOver enabled to operate. Run the sample project Open the Audio Graph detail page, by using VoiceOver, swiping down until you hear Chart details. The chart detail page disappears immediately. Reported FB11479931

Hello! My app has been experiencing some strange crashes in the last few months. The crash log shows it as a Watchdog timeout error of 0x8BADF00D. I knew about this error code before, especially since here is the documentation about addressing-watchdog-terminations. But actually, the call stack shows that the crash appears in dydl and it seems that my app code has not been executed yet. Does anyone know the cause of this problem please? I have observed this crash on iOS 15.6, 15.5, 15.4, and earlier versions.

WCSession.isComplicationEnabled() always returns false on iOS 15.4/15.4.1.

I found a problem with the latest Xcode 13.2/13.2.1 when compiling SwiftUI if-#available structure. When building with Release mode, the app always crashes on an older system. import SwiftUI struct ContentView: View {   var body: some View {     List {       if #available(iOS 15.0, *) {         Text("Hello").badge(1)       } else {         Text("Hello") // 💥 always crash: iOS 14 + release mode       }     }   } } Sample crash log: OS Version: iPhone OS 14.8.1 (18H107) Release Type: User Baseband Version: n/a Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000000 VM Region Info: 0 is not in any region.

The widget family obtained via @Environment(\.widgetFamily) is wrong when preview widgets in Xcode 13.3. The problem can be reproduced by creating a default app project and a widget extension in Xcode 13.3.

I just discovered that the following simple code snippet has a very confusing behavior on iOS 15.0-15.1. When I go to the NavigationLink, the child page pops up unexpectly once the app goes into the background and reopens. This issue does not happen on iOS 14. struct ContentView: View {   var body: some View {     NavigationView {       TabView {         NavigationLink {           Text("👀 Go to background. This view will pop.")         } label: {           Text("Push")         }       }     }     .navigationViewStyle(.stack)   } } You may have noticed that I have nested the TabView in the NavigationView, and this issue is related to this structure. Like many social apps such as Telegram and WeChat, I believe nesting TabView in NavigationView is a widely used structure. I am very hopeful that this issue will be resolved.
