It's borderline worthless. I challenge you to find the Obj-C documentation for CGSize where it actually describes the attributes.
Why is it in Obj-C docs, for the most part, when another type is referenced, that type is not clickable to jump to the other type?
Obj-C docs apparently have been left to die.
What do you mean by "describes the attributes"? There's this:
developer.apple.com/reference/coregraphics/cgsize
which describes the properties, if that's what you mean, though the current generation of docs on the web site does not hyperlink the types. But in Xcode 8.3, if I search for CGSize in the documentation window, I get the same document as above, and on the page for each property the type CGFloat (for example) is a hyperlink to a page that describes it.
(Make sure you choose the Obj-C language version of the pages in each case.)
There is plenty to complain about in the current doc formats (fonts too large, lack of cross references to programming guides), but it doesn't seem true to say that the docs have been left to die.
Anyway, if you have complaints, you should definitely submit a bug report against the documentation.
