2,669 Pointsyou 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!

Courses Plus Student 6,307 PointsI 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.

This allows you to move up or down through the files. You can checkout more Xcode key bindings at Xcode > Preferences > Key bindings
