Is there a difference between IOS & OSX Data Model templates


The reason I ask is that after adding the new BNRItem as an MSManagedObject subclass I noticed that I when I created the Homepwner.xcdatamodeld I selected the OSX core data template rather than the iOS one.

Am I going to have to delete everything I have done and start again?


Since I was getting an illogical crash the first time I executed the app using core data, to be on the safe side, I deleted and recoded it all making sure that I was using the IOS Core Data template for the data model. The crash didn’t happen, but I don’t know if its because I deleted and recreated teh data model and BNRItem or because I deleted the IOS simulator bundle files.
