Looking at the Apple documentation:

This method expects URLString to contain only characters that are allowed in a properly formed URL. All other characters must be properly percent escaped. Any percent-escaped characters are interpreted using UTF-8 encoding.

Likely there's something incorrect in your string, and you need to encode it before passing it to NSURL, you can do this via stringByAddingPercentEncodingWithAllowedCharacters:

if let encodedString = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet() {
    url = NSURL(string: urlString)
}
