Core Data: UIManagedDocument or AppDelegate to setup core data stack? http://stackoverflow.com/questions/14876988/core-data-uimanageddocument-or-appdelegate-to-setup-core-data-stack create a new project using Core Data that is how the Xcode template will do it. You usually do not need to pass your ManagedObjectContext around from viewcontroller to viewcontroller. It is better to create a singleton Data Access layer which can provide context.. the context doesn't already exist it is created and bound to the persistent store coordinator for the application.

If the model doesn't already exist it is created..
