title: macOS App notarisation stuck during upload
body: <p>I have a simple, Swift based, macOS application, written &amp; maintained in Xcode, that I now want to run through Apple's Developer-ID "notarisation" service for distribution. However, whenever I try to upload an archived build of the application, Xcode gets stuck at the <code>"Uploading package to Apple Services..."</code> step of the process.  </p>

  <p>My process is as follows:<br>
   - In Xcode "Build --> Archive"<br>
   - In Xcode's Organizer: Distribute App --> Developer ID --> Upload --> Automatic Code Signing
   - The issue now occurs during upload.</p>
  
  <p>I have already tried notarising a simple sample-app with no code beyond what the standard Swift macOS project template includes and that app also gets stuck at this step. (So this should eliminate issues with the Code / binary of my project itself.)  </p>
  
  <p>I have also attempted to use <code>xcrun altool</code> to upload my binary to the notarisation service using the command: <code>xcrun altool --notarize-app --primary-bundle-id "com.me.myapp" --username "myuser@memyselfandi" --password "mypasswd" --file myfile.zip</code>.<br>
  The result here is similar: The command gives no output and hangs.  </p>
  
  <p>Every time I attempt an upload to Apple Services I also notice that a process called <code>ascp</code> is uploading rather large amounts of data, many multiples of the size of the archive I'm attempting to upload to Apple. I'm not 100% certain of how this might be related, but the process always appears when uploading through Organizer or the <code>xcrun altool</code> command.  </p>
  
  <p>I'm using Xcode 10.2.1 and macOS Mojave 10.14.4. </p>
