Swift 4, 5

UIApplication, UIViewController, UIView, and UIWindow are all UIResponder objects by default which means they can all handle motion events, like shake, without any special configuration. Therefore, simply override the appropriate motion method:

class YourViewController: UIViewController {
    override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
        if motion == .motionShake {
            print("device did shake")
        }
    }
}

Additionally, you can override motionBegan(_:with:) and motionCancelled(_:with:). And unlike overriding certain touch events, there is no need to call super.
