Attempt to fix error.
Unable to get entitlements for client task. Error: Error Domain=NSPOSIXErrorDomain Code=-1 "The operation couldn’t be completed. (POSIX error -1 - Unknown error: -1)"

Add AppDelegate.m and ViewController.m to test target.
This didn't fix error.
All unit tests pass before and after this commit.
