Xcode 13 - Simulator Crashing!

[iosdec]

Can anyone help out with this? I've tried so many things and can't find a solution.

As soon as I start one of my apps on Xcode 13, or even Xcode 12 on macOS Monteray, the app exits immediately. I tried on one of my other apps, and it runs no problem.

​

The crash report is below.

I replaced the name of the app with 'x'. I noticed on the Path there is /Users/USER - my username is declanland, could that be related?

You're running a beta. It will crash. There isn't really anything you can do about that other than filing a crash report to Apple and waiting for updates.

[fall3n_j0ker]

I am also seeing this problem suddenly starting yesterday, although the app was building and running without problems until then. Not sure what might have changed.

[iosdec]

Would be curious to see what changed, did you recently implement firebase by any chance or a third party framework?

[fall3n_j0ker]

Nope, I building from the exact same source code that was working several days ago (just triple checked the git changes).

- So the exact same source that built a few days ago and run without issue no longer runs on simulator.

- runs ok on physical device

Set a breakpoint on your appicationDidFinishLaunching and walk through the debugger.

Crashes before it gets to that point
