Join Simon Allardice for an in-depth discussion in this video Revisiting Core Data store types, part of Core Data for iOS and OS X.
All the applications we have been making are saving to a single physical store file.…We have seen this file a couple of times.…For Cocoa, you can find it by going out to your home folder, then into Library/Application…Support, certainly this is the path if you are accepting all the defaults.…And depending on what you've named that application you'll find an entry, and for me it's under…com.mycompany, you'll find an entry there for the actual saved store file.…Now one thing to be aware of is if you've used multiple projects with exactly the same…name, and same details, for example, a lot of copied projects, say several of the exercise…files, which are just the same project in various saved states, that they'll all be…trying to access the same file path. That may or may not be what you want.…
Now for iOS applications, it is also possible to navigate to the equivalent location for…the simulator, although it's a little more tedious to do because the path is not so obvious.…But again, still in my home folder /Library/Application Support, I actually have an entry here for iPhone Simulator.…

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.
