My application crashes when building to a physical device but is fine in a simulator.

I have uploaded an app twice now to have it rejected due to it crashing upon loading. I have tested and tried this on simulators it works fine, I also have this already working for the android store. Been trying to work this out for a while now but not sure how to fix this moving forwards.

The crash log is as follows:

Any help would be amazing.

Many Thanks,

I have a similar issue with a app that works fine on simulators and on Mac OS but crashes on my iPhone 11 Pro Max. Produces a very similar crash file... Are you using Core Data in your project?

I have tested and tried this on simulators it works fine.

What happened when you tested on an actual device? Ensure you're testing the final build before submitting to the App Store by following the process in Testing a Release Build. The simulator is a useful development tool, but should only complement, not replace, testing on actual hardware.

As to your crash report, you need to symbolicate it to make it useful. Something in your code directly called abort(), and you need those symbols to know what code path chose to abort.
