I'm looking into a crash report in Fabric, and I have no idea what might have caused it. The stack trace is not particularly helpful, however it looks the app was preparing to be suspended in the background. Here is the crash message:
Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x444444444444445

Any idea how I can get to the bottom of this?
Does this seem like it might be a bug in UIKit or QuartzCore, or is it more likely to be a bug in our own code?

i think you are using nil object which is not insalized
I have no idea about this crash. The crash happens at various screens without any actions sometimes. Any help would be appreciated. Thanks in advance.

Could you help me with this mysterious crash? It happens when I re-open the app after a few days, so it's practically impossible to debug it :/
Any clue or idea would be super helpful. I'm kinda lost here. Thank you!
