I managed to break my xcdatamodel file somehow. It shows up in Xcode with three files inside, two of which are red and can't be edited, and a third that has a ? beside it. That file actually exists in the xcdatamodel bundle, the two red ones do not.
So I set the Model Version to select the one that isn't red and ran the app. That gets me a:
Can't find model for source store
I suspect this has something to do with the IDs it uses to find the file?
Any suggestions on where to look? I'd like to remove the links to the non-existent files, and get the one that is there working again.
