The “Quit Game” node doesn’t seem to do anything on tvOS (AppleTV). Is that…expected? Do games not ever shut themselves down on tvOS?
Not really…
So, just like the other Apps on Apple TV, they will just keep on running, but suspended… Like iOS.
If you want to give a ‘Quit Game’ choice, just save the relevant data and return to the start screen for your game.
FYI - While developing, if you find your game unresponsive or stuck somewhere, just double tap the TV button on the Apple TV remote. There you can swipe the applications up and away like on iOS.
Hope that helps!
I will take this as de-facto confirmation that you cannot actually quit a tvOS application. Thank you.
