Best way to delete all specific type of NSManagedObjects?

Nope, that's how you do it. Despite it usually using a database as a back-end data store, CoreData itself is not a database, it's a relational object graph manager. As such, there's no way to delete objects without actually fetching them and telling the context to delete them.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
