Can I enable null reference checking in production code on iOS

Can I enable null reference checking in production code on iOS? I don’t want my app crashing with exc_bad_access when I coud catch the exception and recover cleanly. Performance is not an issue - the development build is plenty fast enough.

Yes, in player settings, set Script Call Optimization to “Slow and Safe”. It’s still up to you to use try/catch to catch all exceptions, but you can simply try/catch in all of your Update() or wherever your code might run.
