CG versus UI. What is the difference?

I am confused when I would use something like CG... or something like UI... because they seem very similar if CG means computer graphics and UI is user interface. I am also talking about using this in swift.

I would recommend looking through Apple's documentation on all the UI classes and all the CG classes. That will help give you a better understanding of each of them and the subclasses available.

I haven't gone through the Swift course yet, but I'm finishing up the iOS track (Obj-C)... But I would say UI classes are more for predefined elements that you need to use, like buttons, tab bars, views, etc... Whereas CG classes can be used to create custom containers, elements, geometry, etc, that do not already have an existing predefined element to use.

I really don't know if I'm making any sense outside of my head, but again, I would suggest taking some time to look through Apple's docs.
