как решить проблему «Не удалось загрузить постоянный магазин по URL»?

Мое приложение падает, когда я хочу опубликовать сообщение на facebook, выбрав iOS simulator 5.0. Я не знаю, как решить эту проблему, вот мое сообщение в журнале

2012-12-28 14:55:19.175 SendQuote[2029:3603] Unable to load persistent store at URL 'file://localhost/Users/winsolutions/Library/Application%20Support/iPhone%20Simulator/5.0/Library/Keyboard/UserDictionary.sqlite' ({
    metadata =     {
        NSPersistenceFrameworkVersion = 419;
        NSStoreModelVersionHashes =         {
            UserDictionaryEntry = ;
        };
        NSStoreModelVersionHashesVersion = 3;
        NSStoreModelVersionIdentifiers =         (
            ""
        );
        NSStoreType = SQLite;
        NSStoreUUID = "5232202C-AF68-41AA-905F-5B023F1954D4";
        "_NSAutoVacuumLevel" = 2;
    };
    reason = "The model used to open the store is incompatible with the one used to create the store";
})

и в конце я получаю это сообщение журнала
