Join Simon Allardice for an in-depth discussion in this video Creating a Core Data project, part of Core Data for iOS and OS X.
The easiest way to get started with Core Data is to do almost nothing.…Now you might think, great, I've been doing that already.…But let me show you what I mean.…Jumping into Xcode, I'm going to create a new project.…Now Core Data is a framework that we can link to and use in any iOS or Cocoa application.…And if you have an existing project which you've written so far without Core Data, then…yes, you absolutely can add Core Data support to that project.…But when you're first learning Core Data, learn it by creating some new projects, even…if you end up just deleting them.…
This is a much easier way to get all the pieces organized in your head before you try and…retrofit those pieces into an existing project with a lot of code.…So in Xcode, three of the built-in project templates for iOS have an option, a check…box to include Core Data support.…And so does the regular Cocoa Application for desktop development.…And the benefit of checking this is not that our project will link to Core Data.…We could do that anytime.…

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.
