Ionic Native Vibration on IOS

Hello guys.

I have a small problem with

As you may know, you can no longer set the vibration time or pattern for ios users. However in my app i am about to create an alarm-clock so it will play a sound or vibrate until the user shake the device. Do you know any workaround for this? Or at least a 30 sec long vibration?

Any update on this ? i need a fast vibration …
