encoding url using swift code

Question

I need to send an URL in Arabic language, so I need to encode it before I put it in URL. I am using Swift code.

Below is an example what i really need

var s = "www.example.com/السلام عليكم"

let url = NSURL(string : s)

So the word (السلام عليكم) is in Arabic characters that what I want to send.
