Detecting shake in AppDelegate

Add the following snippet in your AppDelegate:

override func motionBegan(motion: UIEventSubtype, withEvent event: UIEvent?) {
    if motion == .MotionShake {
        print("Device shaken")
    }
}

Swift 3.0 version:

override func motionBegan(_ motion: UIEventSubtype, with event: UIEvent?) {
    if motion == .motionShake {
        print("Device shaken")
    }
}

As for later versions this does not seem to work anymore. You need to add the above code in your view controller instead

If you want to globally detect shake motion, the UIWindow implements UIResponder that can receive shake motion event. You can add the following snippet to AppDelegate

extension UIWindow {
    open override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
        if motion == .motionShake {
            print("Device shaken")
        }
    }
}
