How to make the device vibrate
All iPhones have a built-in motor to create vibration effects, and if you just want a quick vibration it takes just one line of code:
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)You’ll need to import the AVFoundation framework if you don’t have it already.
That’s not a particularly easy line of code to remember, so why not make it an extension on UIDevice?
extension UIDevice {
static func vibrate() {
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
}
}Now you can just call UIDevice.vibrate() as needed.
Available from iOS 2.0
