I remember having this problem while developing Core Data apps for
testing purposes. It often happened while I modified the app in
various ways.
I think the solution was to delete the store in ApplicationSupport/
<app name>. If you have legacy data, you'll have to export that from
an old version and import to the new one, however.

I've been working on a project that uses Core Data for a while now. I
recently changed the model and ran it, but I noticed an odd behavior:
I wan't informed that the model had changed and was incompatible. I
went ahead and deleted the old xml file and when running the
application again, it created another file. The only problem is that
Core Data has stopped saving. EVery time I open the application, I'm
presented with a blank slate. I haven't been religiously using
subversion, but I had a commit several days, so I checked out that
revision. It has the exact same problem, but I'm certain this wasn't
happening a few days. I'm not sure what I could've done that could
have caused this, but I'm completely stuck and going crazy trying to
get my app to work again.
Thanks,
