We have set up continuous environment at xcode9 at dedicated mac.Xcode-server is set up on that machine and bot has been created to build project and execute tests. Build required cocoapods , hence pre-integration script is also used.
Now, when bot starts UI tests, the app installs at simulator , but doesn't launch and eventually consoles log following error : Test Target 'xx' encountered an error (Early unexpected exit , operation never finished bootsrapping - no restart will be attempted)
On investigation of 'Raw build logs' we found Main Thread Checker error shows up with firebase warning.
Main Thread Checker: UI API called on a background thread: -[UIApplication applicationState] PID: 34330, TID: 355611, Thread name: (none), Queue name: NSOperationQueue 0x600000239dc0 (QOS: UNSPECIFIED), QoS: 0 Backtrace:
Had mitigated this issue by unchecking Edit Scheme->Test/Debug->Main Thread Checker under diagnostic section , while running tests locally.
Does same error showing up at continuous environment means that we have to pass the unchecking of Main Thread Checker as an argument ? Or is there something we are missing ?
Kindly help.
