How to check if Haptic Engine (UIFeedbackGenerator) is supported

Question

I am wondering how we could check if the new iOS 10 API UIFeebackGenerator is available on the current device. There are some more things we would need to check

Answer 1

I made an extension to UIDevice without using the private API

extension UIDevice {

static var isHapticsSupported : Bool {
    let feedback = UIImpactFeedbackGenerator(style: .heavy)
    feedback.prepare()
    return feedback.description.hasSuffix("Heavy>")
}

} and you use it like this :

UIDevice.isHapticsSupported 

returns true or false
