What are the system sound ids for the new keyboard clicks in iOS 10?

Implemented in swift using an enum (extend with your own other system sound id's):

import AudioToolbox


enum SystemSound: UInt32 {

    case pressClick    = 1123
    case pressDelete   = 1155
    case pressModifier = 1156

    func play() {
        AudioServicesPlaySystemSound(self.rawValue)
    }

}

and use like this:

@IBAction func pressedDigit(sender : UIButton) {
    SystemSound.pressClick.play()
}

iOS 10.0 - iOS 11.0 b5

Press Click - ID: 1123

Press Delete - ID: 1155

Press Modifier - ID: 1156

Comment (1): Same IDs work for iOS 11 beta 5
