Do you use animation in your code ?

Could you show the code where the app crashes ?

So, looks like that is not code issue. I did not have crash when testing locally on devices or simulators. Only when i am deploy to testflight and start app i have a crash. I added logs with events to my app. And that crash happens in different parts of my app. In appcenter that crash was not catching. So, i can not show you code where this happens. Only thing that i have is crashlog from test flight. About animation - nope, i did not have.
