Good article, I like these because there are a lot of things I wish I knew when I started iOS development as well 'back in the day' :) Couple nits:
-XIBs are awesome and you should strive to use them, falling back to layout in code when the XIB fails to meet your requirements. Though I'm also finding storyboards hard to swallow for complex projects.
-Blocks and GCD are great tools but with great power comes a lot of complexity and consideration, they could easily get beginners in trouble. I ain't saying don't use em, but There Be Dragons Here.
Bravo on bringing up Singletons, thats something I only recently discovered and wish I had sooner. Also, I feel like a primer on delegates, protocols, notifications and selectors: when to use what and why, would also go a long way in the beginning.
