1.If I have a 10.10 version for Xcode, what is the proper file I should use to work on? Do I just use Cocoa?

2.Also, how does he switch from one page to another without clicking on anything? I think he goes from header to implementation.

Don't worry about having the new Xcode (you have OS X 10.10 and Xcode 6.(idk)) All files will work the same! Cocoa is the framework, and yes you should keep on using the cocoa touch class.

[control] + [command] + [up OR down] to switch between header and implementation

You will get errors mainly because the build settings may be different, and not compatible with Xcode. I can assure you though, if you copy and past the project files code, you should have no problem with Treehouse's source code working on your computer.
