How does he work XCode?

His keyboard tricks are so secretive. He doesn't teach us how to use them, and especially, when I try to type in the code, I'm typing it into my project without knowing what I just typed. Can someone help out?

I don't get how does it switch from the .h to .m files in XCode. He doesn't tell us.

Hey Jacky!

What I do is I pause the video whenever I need to (this is pretty frequent since the teachers are kind of fast). When I pause, I switch over to Xcode and type in the code. After I've typed it in, I stop and read it a few times to understand it. About his keyboard tricks, you can find all of them inside Xcode (top bar) > Preferences > Key Bindings.

Hope this helps!

There are multiple ways to navigate files in XCode but for me the most straightforward is to use the Project Navigator.

It is the first option in the left panel. Toggle on the left pane with ⌘0 and then ⌘1 to select Project Navigator if not already selected.

Here are some good resources on this:

You can option click on anything to pull up the Apple documentation that explains that code.

I recommend just going along with the flow in the videos, (because they go fast), then go back and ask yourself if you understand what each piece does, read up on it if you don't.
