Hi guys, with regards to this video, I understand that after the "Sphere" struct is declared, and usage of "Sphere", "centre", and "radius" take on a turquoise colour. Does this only happen in structs? Or are there other situations where this happens? And when the text does turn turquoise, what does it represent?
Cheers

The color coding of text depends on the text editor and the specifc settings for the text editor. There are a variety of themes available for xcode and the syntax highlighting will be differnet with each theme. The turquoise color is being used for class names and instance variables in this video (this is the default setting). If you look in xcode under Preferences - > Fonts and Colors you can see what color(s) the objective-c syntax will be shown in depending upon the theme. For example constants, type names, methods and function names will all appear in turquoise. The highlighting is just for you, the developer, to more easily recognize objective-c's keywords and syntax.
