Hi there,
I am trying to simulate a haptic feedback on a button press interaction on an iPad. Any pointer on how to implement this, or vibration on IOS safari mobile? 
Hi oliLLo.
There isn’t currently a native way in Axure RP to implement haptic feedback, but I’ll be happy to file this as a feature request with our designated teams on your behalf. In the meantime, I’m hoping this post will help a bit!
