问题
I'm trying to get UI testing set up for my project - I encountered a crash with previous betas. (See this stack overflow question if you are interested)
Anyway, I was quite thrilled to try it with Xcode 7 Beta 5. I created a simple Single Page app, added a text field and button, and ran it in Simulator. The simulator loads but the app doesn't get installed.
I've tried it in different simulators, all iOS 9 - same behavior in all of them.
Anyone else see this behavior? Am I missing something?
