Best way to parse URL string to get values for keys?

Question

I need to parse a URL string like this one:

&ad_eurl=http://www.youtube.com/video/4bL4FI1Gz6s&hl=it_IT&iv_logging_level=3&ad_flags=0&ends

If you're using NSURLComponents the following concise extension will also do the trick:

extension NSURLComponents {

    func getQueryStringParameter(name: String) -> String? {
        return (self.queryItems? as [NSURLQueryItem])
            .filter({ (item) in item.name == name }).first?
            .value()
    }

}
