iOS Core data crash on device not on simulator

luke3 said:

Hello everyone,

I am getting a really weird crash in my app that is using core data. The app runs fine in the ipad simulator, but on the device it crashes... I am getting the error

NSInvalidArgumentException', reason: 'to-many key not allowed here'
*** First throw call stack:

I know the error is talking about if you are trying to sort on a one to many relationship entity. But I know I am not.

Any suggestions?
