Join Simon Allardice for an in-depth discussion in this video What you need to know, part of Core Data for iOS and OS X.
This isn't a beginner class. Core Data is hard.…It is worth it, but it's hard, and it places some expectations on you.…So do this course once you know your way around Xcode and Objective-C, and when you're comfortable…with making a least basic iOS or basic Cocoa applications.…Now, Apple themselves will tell you that Core Data is not an entry-level technology, and…it assumes knowledge of regular Cocoa or iOS development skills.…And we're going to need those skills, things like delegation, target/action, key/value…coding, MVC, inheritance, notifications. I expect you to know these thing.…
Although, if you feel like you're an expert on everything, that's okay as long as you…can look things up when you need to,…although I don't expect you to know anything about Core Data itself.…Now, you might have attempted to learn about Core Data already,…but I'm going to start here as if you hadn't.…I'll begin with the idea that you've heard this term Core Data, you keep hearing it,…you can tell it's something important, but you don't know much about it.…

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.
