The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Here's my own list of the interesting stuff announced during this year's WWDC, collected from the keynotes, various Apple docs, blog posts and tweets.

If you're planning to watch the videos, I really recommend this Mac app that helps you download and watch them: https://github.com/insidegui/WWDC.

	This was nice and fast... but it takes up WAY TOO MUCH space. And it's annoying to write.
	(I like the way I can just step into the function that calls the delegate for debugging)

	What's a better way to not make me call respondsToSelector in the middle of my code? Some proxy?
