Swift - How to add a delay for vibrate

Question

I use this code inside my motionBegan function. And when i shake my device it vibrates. Is there a way to add a delay so vibration begins after 1 second later for example?

    AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

Answer 1

For Swift 3 and up, use a DispatchQueue :

DispatchQueue.main.asyncAfter(.now() + 1.0) {
    AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))
}

Answer 2

Use GCD dispatch_after . (The easiest way is with my delay function, shown here: https://stackoverflow.com/a/24318861/341994 .)
