When I add various frameworks, pictured below (the ones marked in red), my app throws an exception at save. When the app is restarted all data is lost.
I am creating a document based cored data app. All seems ok until I add some frameworks needed to finish the app. By "exception" I mean if I add an "all exceptions" breakpoint the app will stop if I try to save the core data managed document. If I ignore the exception all works until I restart the app, at which point the document is recreated and all saved data is lost. The frameworks that seem to be conflicting with my core data setup : AVFoundation, Twitter, and Social.
Note: (Extra info may be helpful) If I build the app and then add the add these frameworks then rebuild, all works fine as expected. Only when I delete the app from my device then rebuild with these frameworks already included I get the exception and issue described.
Strangely, autosave seems to work fine. It's only when I use: [myManagedDocument saveToURL:myManagedDocument.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:handler]; that I get the exception.
