Swift 3 URLSession mit basic authentication

Ich hatte ein paar Probleme mit Swift 3 eine URLSession mit aktivierter Authentifizierung zustande zu bekommen. Viele Anleitungen gelten noch für Swift 2, hier mal mein Code (Am beispiel einer Json Abfrage):

let url = URL(string: "http://blublbub.com/json")!
        print (url)

        let config = URLSessionConfiguration.default
        let username = "user"
        let password = "password"
        let loginData = String(format: "%@:%@", username, password).data(using: String.Encoding.utf8)!
        let base64LoginData = loginData.base64EncodedString()
        let authString = "Basic \(base64LoginData)"
        config.httpAdditionalHeaders = ["Authorization" : authString]

        let urlSession = URLSession(configuration: config)

        let task = urlSession.dataTask(with: url) { (data, response, error) in

            let jsonData =  try! JSONSerialization.jsonObject(with: data!, options: []) as? [String: AnyObject]


            }
        }

        task.resume()

Zusätzlich hier noch ein snip für HTTP Requests:

let devURL = URL(string: "http://url.com")

let username = "user"
let password = "password"
let loginData = String(format: "%@:%@", username, password).data(using: String.Encoding.utf8)!
let base64LoginData = loginData.base64EncodedString()

//HTTP Request:
let request = NSMutableURLRequest(url: devURL!)
request.httpMethod = "GET"
request.setValue("Basic \(base64LoginData)", forHTTPHeaderField: "Authorization")

let task = URLSession.shared.dataTask(with: request as URLRequest){
    data, response, error in
    if error != nil{
        print("error=\(String(describing: error))")
        return
    }

    let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
    print("responseString=\(String(describing: responseString))")

}

task.resume()
