How to trigger vibration on Apple Watch OS 2?

Question

I have been working with Apple Watch OS 2 for a while, but have not succeeded in triggering vibration on Apple Watch standalone app in Swift, using Xcode Version 7.0 beta 6 (7A192o).

All tutorials using vibration on iPhone in Swift look like:

 import AudioToolbox
 ...
 AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

But I cannot import the AudioToolbox library.

I get the error:

Could not build Objective-C module "AudioToolbox"

Has anyone already found the way to do it?

Answer 1

You can generate haptic & auditory feedback, using:

WKInterfaceDevice.currentDevice().playHaptic(.Click)

'Click' is one of the 'cases' (types of vibration/beeps) that you can choose, cfr:

enum WKHapticType : Int {
 

case Notification
 
case DirectionUp

case DirectionDown
 
case Success

case Failure
 
case Retry
 
case Start
 
case Stop
 
case Click

}

This only works on the device, not in the simulator.

Answer 2

In Swift 3:

WKInterfaceDevice.current().play(.success)

Answer 3

I'm not a expert in WatchKit but I know that with Watch OS 2 you can use:

WKInterfaceDevice().playHaptic(.Notification)

The function playHaptic called on a WKInterfaceDevice instance engage the haptic engine in Apple Watch.

See more in the Apple documentation.

WKInterfaceDevice.currentDevice().playHaptic(.Notification)
