Your app has crashed because of an unhandled language exception. In frame 6 UICollectionView is calling your code. Frames 4 and 5 are your code, and in frame 3 it does something with Core Data. I think it’s trying to set a properly on a managed option (in _sharedIMPL_setvfk_core, vfk is short for value for key). Something has gone wrong with that and Core Data has raised this exception. If you managed to reproduce this locally, you’d be able to see the helpful message that Core Data has included with this exception. Sadly, that’s not captured by the crash report.
A good place to start with this would be to symbolicate your crash report to uncover the identity of the code in frame 4. For advice on how to do that, see Adding Identifiable Symbol Names to a Crash Report.
