I'am getting
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSManagedObject persistentStore]: unrecognized selector sent to instance 0x3bebf50'
and
while loading data from core data.I have referred links iOS Persistent store issue but it didnt solved my issue. Also data not saving to tableview. Earlier it was loading but due to large data I've used background core data saving. but for now No data loading from DB. I'm using NSFetchResultController for fetching data.
