Declaration
var sender: URLAuthenticationDiscussion
If you are using the URLSession API, this value is purely informational, because you must respond to authentication challenges in your URLSession or URLSession implementations, by passing URLSession constants to the provided completion handler blocks.
However, if you are using the legacy NSURLConnection or NSURLDownload API, you use this object directly in your authentication handler delegate method. With these APIs, after you finish processing the authentication challenge, you respond by calling methods defined in the URLAuthentication protocol on this sender.
