If you extend the Dictionary type you can use the already defined generic Key directly.

extension Dictionary {
    // Key and Value are already defined by type dictionary, so it's available here
    func getSomething(key: Key) -> Value {
        return self[key]
    }
}

This works because Dictionary already has generics Key and Value defined for it's own use.
