title: NSURLSession bandwidth limiting
body: <p>Is there a way to limit the bandwidth in <strong>NSURLSession</strong>?</p>
  
  <p>I'm making file-sync-client for macOS like <code>Dropbox/GoogleDrive/pCloud</code> and they all have bandwidth limiting options, but I'm not sure how to configure <strong>NSURLSession</strong> to respect bandwidth limiting.</p>
