Attaching a crash report: 2024-12-02_21-50-20.3400_-1000-eb116a1c71b8d354e66d6ecfc079873406aefab4.crash

Thanks for you response. The issue ended up being that we had mistakenly created 2 UITabBarController instances and moved the child viewcontrollers over to the one that wasn't being displayed. The crash occurred when a tab bar item was tapped and the associated viewcontroller was referencing the other UITabBarController instance.

In case this is helpful for anyone, I got this response from Apple: Looking through your crash logs the cause appears to be related to the use of gradient layers. This is either causing a memory allocation error or some other problem in your app. Please review your use of gradient layers.
