Hey Charlie,

I went ahead and updated the NSURLSession for the swift section. Might want to double check it, though.

Also is the AFNetworking code correct?

Thats awesome! I have not looked closely at the AFNetworking code. It likely needs updates too.

Hey @dustynaugust Thanks! I made a few more edits and modeled after fetching a Movie, since the Instagram api isn't super relevant anymore. 👍
