Yes, and this is a really shame. Several years ago I was able to become an iOS developer almost completely by reading through Apple's docs and then building a couple of projects on my own. I had a checklist of the programming guides to work my way through from Objective-C, to App Programming, to view controllers, and on. Over the years I found it more and more frustrating to truly understand new frameworks as the documentation changed. iOS development is now a small portion of my job and the lack of good resources is making it hard to stay up to date.
