title: unable to get the video on web browser using GCDWebServer in swift
body: <p>I created a small demo app where app access the image and videos from iPhone using UIImagePickerController.
  When I select any image or video, app creates a copy of it( image or video) in document directory.
  And  create a web server on iPhone using GCDWebserver and need to expose the selected image or video.
  But it does not work.</p>
  
  <p>Here is the sample code, not sure where I could be wrong.</p>
  
  <pre><code>class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
  
  @IBOutlet weak var btnselect: UIButton!
  let videoPicker = UIImagePickerController()
  
  @IBAction func btnSelect(_ sender: Any) {
  
          if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
              let myPickerController = UIImagePickerController()
              myPickerController.delegate = self;
              myPickerController.sourceType = .photoLibrary
              myPickerController.allowsEditing = false
              self.present(myPickerController, animated: true, completion: nil)
          }
  
      }
  
  func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
          self.dismiss(animated: true, completion: nil)
      }
  
  func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
  
      // 1. saving video to documents directory
  
        let videoURL = info[UIImagePickerController.InfoKey.mediaURL] as! NSURL
              let videoData = NSData(contentsOf: videoURL as URL)
              let path = try! FileManager.default.url(for: FileManager.SearchPathDirectory.documentDirectory, in: FileManager.SearchPathDomainMask.userDomainMask, appropriateFor: nil, create: false)
  
              let newPath = path.appendingPathComponent("/myTestVideo.mp4")
              do {
                  try videoData?.write(to: newPath)
              } catch {
                  print(error)
              }
  
  
   // 2. Create web server on iPhone using GCDWebServer
  
          let webServer = GCDWebServer()
          webServer.addDefaultHandler(forMethod: "GET", request: GCDWebServerRequest.self, processBlock: {request in
          return GCDWebServerDataResponse(newPath)
  
         })
         webServer.start(withPort: 8080, bonjourName: "GCD Web Server")
  
  }
  }
  </code></pre>
  
  <p>I need this selected (image or video) to be hosted/accessible by this GCD Web Server.</p>
