It’s hard to offer specific insight into this because I don’t maintain expertise in third-party tooling. I usually recommend that folks in your situation ask for help via the support channel for the tools they’re using. However, I can offer some general advice. My experience is that, when an app fails to launch like this, without generating a crash report, it’s usually because the third-party runtime has detected a problem and called exit. That’s fine during debugging, because you can get a breakpoint on exit and look at the backtrace. However, it’s problematic when the app is Distribution signed, because you can’t attach with the debugger. My usual advice here is to use Xcode to export a Development signed app from the same Xcode archive that you submitted to TestFlight. See Isolating Code Signing Problems from Build Problems. I’m not sure how well that’ll map to your third-party tooling. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple
