Switch to Implementation window
How did he switch from interface to implementation tab/window (around 5:20)? Is one the .h file and the latter .m? Please help!

Yes. Exactly, the implementation file is the ".m" file and the header file is the ".h" file. Unfortunately, it's not very clear in the video that he's switching between the two. Usually you would see the change in Xcode on the left-hand window showing the file structures.
Don't worry - after you see the syntax over and over you'll get used to it.
