My app crashes when not launched from Xcode
Until today was running fine, with and without Xcode. But then I upgraded the device to iOS 14.2 beta and Xcode 12.1 to test some stuff. Then I ran the app with Xcode without problems but when I tried to run it without Xcode attached it simply crashes.
I'm guessing any of my 3rd party libraries might not be compatible with the coming iOS 14.2? But then how do I find which one?
How can I debug this if just happens when the app is not debugging?
Thanks in advance.
Edit: I was able to use Xcode to retrieve this crash log:

pistoleta1 Answer
As the error message tells you, "process-launch watchdog transgression: exhausted real (wall clock) time allowance of 20.00 seconds". Your app is taking too long to launch.
The reason this doesn't happen when launching from Xcode is that the watchdog is turned off under those circumstances. But it is still taking too long to launch, even from Xcode!
The reason for taking so long is that you have misunderstood how to launch. Do not perform tasks during launch (on the main thread). Your job during launch is to get out of the way and let the device launch the app and get it running. The best thing for you to do during launch is nothing. Just stand back.
If you have time-consuming tasks to perform, do them later and on a background thread.
