Need to symbolicate crash log EXC_CRASH (SIGABRT)

Question

I need to symbolicate apple crash log

I don't have any crashes when running my app on all supported devices on XCode simulator but apple reviewer tells me that my app crashes on launching and send me this crash log if someone could symbolicating this crash log so I can find the crash. This is a link for crash-log.txt file

this is my Main VC if it helps finding crash

Normally we are run and test our apps in debug mode.Sometimes apps working properly on debug mode,But will be crash on release mode. It may cause frameworks,cocoapods or other methods that we use to build our app.

go to edit scheme and change your build configuration debug to release mode. then run your app on real device.Now you get the errors that apple get If some issue have with your app.
