Guys I just want to say thanks for devoting a small chapter into Apple’s documentation.
I’ve always treated the documentation as a guide - but I only ever searched for stuff. I never used it to just look around as I didn’t really know that was an option. I always though you have to just “know” the name of your class you want or a close enough name to it.
However, after reading this chapter I now know the Apple documentation is invaluable and full of resources to help you along.
