Swift 3 compatibility

[lfarah]

Hey, I'd love to see this lib available in Swift 3 so I can implement it in my project.

Thanks 😄

@lfarah Hi, I'm working on it now. Will push it asap!

The current module works in Swift 3 ( for me at least ) with a lot of compile warnings.

There's a PR for this. If you don't want to wait for it to be accepted you can use this fork.
