this is happening sometime to CLIENT, I almost can't reproduce this and I do not get any crashes neither in Xcode organiser nor in Crashlytics
I can just get the logs from the device -> setting-> privacy-> analytics I have worked very hard to remove all memory leaks and to clean the main thread as I can move the task to DispatchQueue.background also, I have cleaned logic from AppDelegate functions and it still happens.

Please advise!

Code 0x8badf00d is the error code that the watchdog raises when an application takes too long to launch or terminate.

Usually, it means you either have an infinite loop somewhere, or you are waiting for network IO on the main thread. There's also the possibility that the user is force-quitting the application.

You can refer https://developer.apple.com/library/archive/qa/qa1693/_index.html apple's reference document for more details and the possible ways to handle this scenario in your project.
