iOS 10 iPhone 6S Play Haptic feedback or vibrate using taptic engine

Question

Iphone6s has taptic engine or not, can I use a public API called UIFeedbackGenerator to access it?

Answer 1

Haptic feedback engine have been introduced in iPhone7/7+ and you can use it via UIFeedbackGenerator, here's an example:

let generator = UIImpactFeedbackGenerator(style: .heavy)
generator.prepare()

generator.impactOccurred()

As for iPhone 6S/6S I've found kind of fallback, please try it and describe the experience if you do have the device:

import AudioToolbox


AudioServicesPlaySystemSound(1519) // Actuate `Peek` feedback (weak boom)
AudioServicesPlaySystemSound(1520) // Actuate `Pop` feedback (strong boom)
AudioServicesPlaySystemSound(1521) // Actuate `Nope` feedback (series of three weak booms)

I've tried to summarize everything I found with regards to the Haptic feedback here: http://www.mikitamanko.com/blog/2017/01/29/haptic-feedback-with-uifeedbackgenerator/
