I had a look at your code and at a first glance it looks quite good to be your first Swift project. As the others already said, you're missing tests that makes refactoring a bit hard for someone who's new to your code.

Other 2 points I noticed is:

1) You're using CocoaPods but you included SwiftyJSON, Alamofire and a couple of other libraries as plain source code. Why not submodules at least? This makes it hard to update the source of the external dependencies to the latest version

2) You're doing way too many casts in your code. This means that something could be wrong on an architectural level. I would like to help you (I already cloned your repo) but I'm using Swift 1.2 (btw your code is still on Swift 1.1) and I didn't manage to migrate because of point 1).

Apart from that, good job on shipping your app! :)
