Search anywhere and could not found an answer. I have this issue causing the app to crash on many users.
How many?
MANY!
I can't reproduce the crash and I can't understand anything from the Crashlytics logs:
After reading some questions and answers around I suspect that something in ManagedObjectContext cause it.
