Upgrade to Swift 2

[aslakg]

The latest version of XCode / Swift breaks the project - would love to see continued work on this excellent project...

I won't have time for the forseable future unfortunately. Any volunteers?

Oh, come on.

Please, you've got the only framework for Swift, and I'm pretty new, so it's going to take some adjusting from Objective-C.

[losh11]

@Sjors if you aren't going to work on these frameworks in the upcoming future - I shall fork them and fix them in my repos.

[Sjors]

@losh11 awesome, it would be great if others help out with this project. But keep in mind that this is far (and I mean far) from ready to use. If you want to ship an app I recommend that you look for a more mature framework, even if it's in Objective C.
