Crash in production build only, EXC_BAD_ACCESS KERN_INVALID_ADDRESS

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000



2 UIKitCore -[UIView traitCollection] + 176



This crash is only happening in production and on iOS 12 devices. The only line in the crash report that is part of my app is the AppDelegate class definition which obviously isn't helpful.



I have tried opening it up using the Crashes Organizer and it doesn't seem to know what to do when I hit "Open in Project". This crash is mostly happening in iOS 12 but have seen a couple instances on iOS 11.

  • It actually crashed in your app from the following line: MyApp 0x0000000104babe54 0x104ba4000 + 32340. Try symbolicate this line and find where it actually crashed. The documentation can be found in here: developer.apple.com/library/archive/technotes/tn2151/…

  • @meim - Sorry, I should have posted the correct one 49 MyApp 0x1009f3e54 main (AppDelegate.swift:20)

  • I think ARC is deallocating object and you are trying to access that object. please debug through code and see all variable values on debug area.

  • How do I debug through code if I can't reproduce

  • It actually crashed in your app from the following line: MyApp 0x0000000104babe54 0x104ba4000 + 32340. Try symbolicate this line and find where it actually crashed. The documentation can be found in here: developer.apple.com/library/archive/technotes/tn2151/…

  • @meim - Sorry, I should have posted the correct one 49 MyApp 0x1009f3e54 main (AppDelegate.swift:20)

  • I think ARC is deallocating object and you are trying to access that object. please debug through code and see all variable values on debug area.

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000



2 UIKitCore -[UIView traitCollection] + 176



This crash is only happening in production and on iOS 12 devices. The only line in the crash report that is part of my app is the AppDelegate class definition which obviously isn't helpful.



I have tried opening it up using the Crashes Organizer and it doesn't seem to know what to do when I hit "Open in Project". This crash is mostly happening in iOS 12 but have seen a couple instances on iOS 11.
