How to respond to the device being shaken
Swift version: 5.4
You can make any UIViewController subclass respond to the device being shaken by overriding the motionBegan method. This is use to handle motion (shaking) but in theory also remote control actions – although I can't say I've ever seen someone write code to handle that!
This code will print a message every time the device is shaken:
override func motionBegan(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
print("Device was shaken!")
}
