you are not alone! I feel like i'm just typing in code without knowing why I'm doing it.

Code like -(void)setRadius:(float)radius { _radius = radius;

doesn't help either. there's 4 radius'. How is anyone suppose to follow that!

I have also question, what does he clicks on 5:23 (an implementation)? and also the video is too complicated and he doesn't explain all the terminology.

Hey georgekiknadze he happens to use a shortcut into going to a different file. ctrl + cmd + up/down This allows you to move up or down through the files. You can checkout more Xcode key bindings at Xcode > Preferences > Key bindings
