A lot of compile errors.

I compile with Xcode 6.2, and there are a lot of errors. like:

1. @objc is only available for class type.
2. as! should be as.

for me, these look like the code is written in old swift(it changes a lot).

Haha that's hilarious! Old Swift...
Man that's the new Swift! :-)
If only you would have bothered actually reading the bold letters in the README at the top, specifying that you need to compile with Xcode 6.3...
