title: Xcode 12 SPM does not fetch packages
body: <p>I've been seriously frustrated with SPM, I am simply unable to fetch packages. Would really appreciate any suggestions you may have.</p>
  <p>When I open Xcode project my laptop is unable to resolve SPM packages that does work on another computer.</p>
  <p>I get the following error message for every package:</p>
  <p><code>Missing package product 'Alamofire'</code></p>
  <p><a href="https://i.stack.imgur.com/jKGH1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jKGH1.png" alt="enter image description here" /></a></p>
  <p>If I remove the package and try to add it manually via</p>
  <ul>
  <li><p><code>File &gt; Add Package dependency</code></p>
  </li>
  <li><p>Put URL: <a href="https://github.com/Alamofire/Alamofire.git" rel="nofollow noreferrer">https://github.com/Alamofire/Alamofire.git</a></p>
  </li>
  <li><p>It then asks me sign in with Github account (even I have already added Github Account to Xcode and this is public repository).</p>
  </li>
  <li><p>After logging in it asks me to input version and upon clicking Next says &quot;The repository could not be found. Make sure a valid repository exists at the specified location and try again.&quot;</p>
  </li>
  </ul>
