iOS UITesting How to Dismiss Popover

I have a pretty complicated app with a lot of views and popovers for fast picking entries.

I'm not able to dismiss a popover. I tried a lot like:

• Hitting coordinates in the window
• app.otherElements["PopoverDismissRegion"] Hitting elements behind the
• popover (which are not hittable at all)

When I record the it in XCode I get: app.otherElements["PopoverDismissRegion"]

Which makes no sense to me.

Hope someone can help.

Thx

Infos: iOS 10.2,Xcode 8.2.1, iPad Air 2 (Device and Simulator, same results)
