If users press the menu button multiple times from any page, it is likely to exit the app. I think it would be nice to have an alert before exiting the app. I have noticed that some apps on other platforms have this feature; however, I am not sure if it is allowed on tvOS.
The logic would be something like this:
Users tap the menu button.
Show an alert with 'Cancel' and 'Exit' buttons.
If 'Cancel' is tapped, go back to the app.
If 'Exit' is tapped, exit the app by calling UIApplication.shared.perform(#selector(NSXPCConnection.suspend)).
Will calling NSXPCConnection.suspend get my app rejected from Apple? It seems like a reasonable feature, though."
