CoreData: Fetch count of to-many relationship with NSDictionaryResultType

Question

I have a big list of objects in Core Data (about 50 000 and periodically increasing). I fetch it with the following request:

NSFetchRequest *fetchRequest = [         


        

Answer 1

If you don't want to fetch all songs, but want to fetch their count number, maybe you should add a new property count, which will you increase as you add new song
