I labored on a iOS undertaking. 4 months in the past, this iOS app all the time crash instantly. I’ve Firebase Crashlytic to observe however I can’t discover which a part of code has concern. And in my system, I can’t reproduce the crash as nicely. I additionally do not know how one can learn the crash report, does anyone have some tutorials to learn that? I don’t know what I have to study to learn it.
Right here is the exception:
Deadly Exception: NSInternalInconsistencyException
Modifications to the format engine should not be carried out from a background thread after it has been accessed from the principle thread.
I do know that every one of UI replace must be on most important thread and I verify with my code many instances. I do not see any warning within the terminal. Every part appears good.
Right here is the entire report in Firebase:
