Does it maybe make sense to mention here that the Cocoa SDK needs this for a working watchdog termination logic. We have a soft contract here, that is very easy to break if somebody removes the delay below or posting the notification.

NotificationCenter.default.post(name: UIApplication.willTerminateNotification, object: nil)

// Close the app after a slight delay so it has time to execute code for the notification
DispatchQueue.main.asyncAfter(deadline: .now() + 0.3) {
// We need to exit since iOS doesn't start the install until the app exits
exit(0)
}
}
}
}
