Answer 1

To prevent wasting time dealing with it.

The complete snippet based on @dgatwood answer

private func http(request: URLRequest){
        let configuration = URLSessionConfiguration.default
        let session = URLSession(configuration: configuration, delegate: self, delegateQueue: .main)
        /*Tweaking*/
        let task = session.uploadTask(with: request, from: request.httpBody!)
        task.resume()
    }

And.. do not forget to add the Headers on request object like

request.setValue("multipart/form-data; boundary=\(yourboundary)", forHTTPHeaderField: "Content-Type")
