Using Xcode 4.5.2, the Baseline project crashes when building to the 6.0 iPad simulator with (summarized) error: “PPRecipesDetailViewController valueForUndefinedKey - not KVC compliant for detailDescriptionLabel”. This is fixed by wiring the misnamed outlet in MainStoryboard_iPad/PPRecipesDetailViewController to the descriptionLabel.
Project then builds and launches, presenting alertView with (summarized) error message: “The recipes database is either corrupt or was created by a newer version of Grokking Recipes.”. The app then closes.
I don’t understand in PPRAppDelegateAlt2, in the initializeCoreDataStack method where this error message and alertView are defined, why there is no checking for a condition appropriate for this message and the need to exit the app.
