How to terminate an app programmatically in iOS 12

Question

I have a problem I put my iPhone 6 on iOS 12 beta 1 and that\'s so a method in my application to close when press on a popup button doesn\'t works on iOS 12 but works on iOS 11.

Answer 1

Try this code :

DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
    UIApplication.shared.perform(#selector(NSXPCConnection.suspend))
     DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
      exit(0)
     }
}

This will wait 1 sec and app will take 0.5 second to close. You can dim display before this code snippet.

Answer 2

You can call exit method

exit(-1)

or you can use NSXPCConnection.suspend

UIControl().sendAction(#selector(NSXPCConnection.suspend),
                       to: UIApplication.shared, for: nil)

Besides Apple isn't recommending to force terminate your app. It doesn't matter how you do that.
