How to make the device vibrate

Paul Hudson    February 13th 2018    @twostraws

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
