crash on coredata ios8

Question

I have a crash on CoreData when I save :

2014-09-16 09:51:58.273 My_app[2678:105246] *** Terminating app due to uncaught exception \'NSInvalidArgumentException\         


        

Answer 1

I'm also seeing this exact error on iOS 8 simulator and can't figure out what I'm doing wrong. I was able to work-around the issue by using @try/@catch but I'd rather understand where the conflict is or if I'm doing something wrong.

@Ryan - do you have the apple issue/link you could post here? What about the sample project?
