Is it possible to trigger a haptic feedback without the accompanying sound on apple Watch OS 2

Question

Assuming the user has not muted their watch sounds. Is it possible for an apple watch app to trigger a haptic feedback (i.e vibrate) without the accompanying sound.

This is different than receiving a notification which is handled automatically by the watch. In this case I'm invoking the haptic feedback using a watch app.

like this: [[WKInterfaceDevice currentDevice] playHaptic:WKHapticTypeClick];

Answer 1

There is a hacky way to do so. You can start to play WKAudioFilePlayer right before haptic and there will be no sound:

player.play()
WKInterfaceDevice.current().play(.click)

I suggest you to create a short silent (very low amplitude and high pitch) audio file for this purpose. And remember that this solution can be buggy.
