Vibrate iPhone 6S manually like peek and pop?

Question

How can I manually trigger a single click-like vibration like the ones that happen when using peek&pop, or application shortcuts?

Answer 1

This method is easy to implement and it works really well (I tried it myself)

import AudioToolbox

AudioServicesPlaySystemSound(1519) // Peek feedback
AudioServicesPlaySystemSound(1520) // Pop feedback
AudioServicesPlaySystemSound(1521) // Three pulses feedback

I hope this helps! :)
