How can I programmatically find Swift's version?

Question

I know I can find the version of Swift I\'m running right now reverting to a Terminal and typing:

xcrun swift --version
Swift version 1.1 (swift-600.0.57.4)

From your comment:

I want to check because different versions of Swift have different features

You should not check the version of your programming language in order to use some features or not. This approach is much better:

if (self.respondsToSelector(Selector("yourMethodSelector"))) {
    self.yourMethodSelector(test, sender: self)
} else {
    //error handling
}

Just check whether a method is available or not.
