Answer 1

If Your Url Contain Spaces than it will Return Nil

Try This:

let url = NSURL(string: urlString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)
let request = NSURLRequest(URL: url!)

Answer 2

try this one :

let url = NSURL(string: "http://www.google.com")
let request = NSURLRequest(URL: url!)
