Join Simon Allardice for an in-depth discussion in this video Final thoughts: Back to the stack, part of Core Data for iOS and OS X.
What I wanted to do with this course is take you through the things that you will always…need in every Core Data application you make, managed objects, and managed object models,…managed object context, fetch requests and fetch results controllers, validation, undo,…and redo, importing, and migration.…At the beginning of this course I showed a diagram of interrelated objects, which should…hopefully make a lot more sense now, because you have all the pieces in place.…We know that we start with the data model defining our entities, the descriptions of…our attributes, our default values and relationships.…
Those entities will be gathered together into a managed object model, that's what the data…model file will be turned into when our application runs and those entities used to create our managed objects.…We have the all important managed object context.…The beating heart of Core Data, the scratchpad, or workbench, for all your managed objects.…It's the context that contains them all, it's the context that we use to perform fetch requests…

Q: In the CoursesViewController.m file, I receive a message that the method dismissModalViewControllerAnimated is no longer supported by Apple. Is there a newer method to use?
A: You may have received the warning that a call to the dismissModalViewControllerAnimated: method is now deprecated.
This is a recently deprecated method, so the code _will_ continue to work using that call, but to remove the warning, change the code from:
to the current recommended version:
[self dismissViewControllerAnimated:YES completion:nil];
It should take care of that message.
