React Native app crashing on iOS 16.2

The only thing you can learn from this crash report is that you need to ditch the third-party crash reporter that you’re using in your app )-:

Consider this backtrace:

Thread 0 Crashed:
0   libobjc.A.dylib          … class_createInstance + 4

Frames 183 through 182 indicate that your third-party crash reporter has caught a signal. Later on, in frame 178, it calls into Objective-C. This is completely bogus. Async signal handlers are not allowed to call Objective-C, or Swift, or even allocate memory with malloc. Some of the time that’ll work but it’s never actually correct. And in this case it’s seems to have been working OK until you get to frame 0 and something went horribly wrong.

So, here’s what’s happened here:

1. In frame 184 your app has actually crashed.

2. In frame 178 your third-party crash reporter has started breaking the rules.

3. In frame 0 that’s caught up with it, and your crash reporter has crashed.

4. The Apple crash reporter caught that and generated this crash report.

There’s nothing you can learn about the original crash from step 1 here; the Apple crash reporter has captured the state of your crash reporter failing in step 3. The original crash state is gone.

Remove your third-party crash reporter and see if you can capture some ‘clean’ crash reports for this.
