I created a brand new empty apple watch app in XCode 7.0 beta 3 (7A152u).
In the simulator it runs fine, however I can't get it to work on a real apple watch. The app launches but watch device is stuck on a spinning wheel loading screen and the xcode debugger says nothing about what's going on.
My apple watch runs the latest watchOS 2.0 beta, my iphone is a 5s with the latest iOS 9.0 beta.
Any idea on what is happening and how to debug this issue?
I have already tried creating a new project, cleaning the project, deleting the app on the iphone, restarting my mac, the iphone and the apple watch.
UPDATE July 28 2015:
Updating to the beta 4 (both for iOS9, watchOS2 and XCode7) didn't solve the issue. Now the app is stuck in the Installing... state in the iOS Watch app.
