title: Swift 4 URL download not working
body: <p>I am trying to download an image from this url:</p>
  
  <pre><code>https://​i.ebayimg.com/00/s/MTA2NlgxNjAw/z/TaoAAOSwjkdZ57Jm/$_2.jpg
  </code></pre>
  
  <p>Using this code:</p>
  
  <pre><code>    guard let escapedQuery = rawUrl.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed),
      let url = URL(string: escapedQuery) else { return }
  
      // check if image is new image, if not, stick with the old image
      if(previousUrl != rawUrl){
          previousUrl = rawUrl
          showActivityIndicatory()
          print("Download Started")
          // download the image from the provided url
          getDataFromUrl(url: url) { data, response, error in
              guard let data = data, error == nil else {
                  DispatchQueue.main.async() {
                      // stop the animation/loading icon
                      self.imageLoadingIndicator.stopAnimating()
                      // set a default placeholder image
                      self.image = #imageLiteral(resourceName: "CellDefaultImage")
                  }
                  return
              }
              print(response?.suggestedFilename ?? url.lastPathComponent)
              print("Download Finished")
              DispatchQueue.main.async() {
                  self.image = UIImage(data: data)
                  self.imageLoadingIndicator.stopAnimating()
              }
          }
      }
  
  }
  
  func getDataFromUrl(url: URL, completion: @escaping (Data?, URLResponse?, Error?) -&gt; ()) {
      // try to download the raw data on a different thread to provide optimal perfomance regarding UI
      URLSession.shared.dataTask(with: url) { data, response, error in
          completion(data, response, error)
      }.resume()
  }
  
  func showActivityIndicatory() {
      imageLoadingIndicator.center = self.center
      imageLoadingIndicator.startAnimating()
  }
  </code></pre>
  
  <p>But I am constantly running into : HTTP load failed (error code: -1200 [3:-9802]) or error code -1002 etc. </p>
  
  <p>Could someone point out what is wrong, perhaps my image url formatting is wrong?</p>
