I actually subscribed to TeamTreehouse because I wanted someone to hold my hand to introduce me to iOS. It was a good experience.

For background, I've been programming for 20 years, first in Basic, then PHP, Javascript, R, (a very small amount of) Common Lisp, and Go. Given that I currently have little free time, it's quite nice to have someone show you a Good Way to write idiomatic code in a new language.

I found their (high, compared to blog posts) pricing to be a positive indicator of quality, and their videos and code seemed to match.
