I just confirmed that the project runs fine on my non-Catalina system. This issue arised after updating to 10.15.2.On non-Catalina system, I am running Xcode 11.3 and everything is fine.
I get the same thing a LOT when I background an app with a map showing. My map has several circular regions and a current location marker.
Intel-based Big Sur here with same issue. I installed another app at the same time and it hung as well. After rebooting, the other app said it was done but Xcode was still hung.
Looks like it's downloading VERY slowly and the progress within the App Store application doesn't match the progress of the Xcode.app progress wheel in from Finder in the Applications folder. It's been downloading/updating for 6 hours...almost done.

A reboot fixed mine.
I was able to reproduce this on iOS 17 by animating the view transitions by changing the top level MyApp to:
@main
struct MyApp: App {
@State private var store = Store()
var body: some Scene {
WindowGroup {
if store.shown {
ContentView()
.transition(.move(edge: .bottom))
} else {
EmptyView()
.transition(.move(edge: .bottom))
}
}
.environment(store)
}
}
and the DetailView to:
struct DetailView: View {
@Environment(Store.self) private var store
var body: some View {
Button("Pop to top") {
withAnimation {
store.shown = false
}
}
.task {
print("DetailView task executed")
}
.onAppear {
print("DetailView appeared")
}
.onDisappear {
print("DetailView disappeared")
}
}
}
By the way, this only happens in this simple reproducer if the DetailView is shown from the ContentView within the NavigationView.
