1.WatchOS View如何全屏。

当我们开发WatchOS App时，会发现WatchOS Status Bar占用Header区域，有时候我们需要把App全屏幕。

可以用.edgesIgnoringSafeArea(.all)

struct XXXXXXXXApp: App {
    
    @WKExtensionDelegateAdaptor(ExtensionDelegate.self) var extensionDelegate
    
    @Environment(\.scenePhase) var scenePhase
    @SceneBuilder var body: some Scene {
        WindowGroup {
            // !!!Remove any NavigationView and use edgesIgnoringSafeArea and it works!!!
            // NavigationView {
                ContentView().edgesIgnoringSafeArea(.all)
            // }
        }.onChange(of: scenePhase) { newScenePhase in
            switch newScenePhase {
            case .active:
                print("active")
            case .inactive:
                print("inactive")
            case .background:
                print("background")
            @unknown default:
                print("default")
            }
        }

        WKNotificationScene(controller: NotificationController.self, category: "myCategory")
    }
}
