title: Signing for "AUv3FilterExtension macOS" requires a development team
body: <p>I want to learn to create Audio Units and have downloaded the AUv3FilterExtension example. I wish to develop and run the component on my Macbook Pro (Catalina). However I get the following error when I try to build using Xcode 11.5:</p>
  <p><strong>Showing All Issues
  Build target AUv3FilterExtension macOS of project AUv3Filter with configuration Debug
  error: Signing for &quot;AUv3FilterExtension macOS&quot; requires a development team. Select a development team in the Signing &amp; Capabilities editor. (in target 'AUv3FilterExtension macOS' from project 'AUv3Filter')</strong></p>
  <p>In <em>Signing &amp; Capabilities</em> I have:</p>
  <ul>
  <li>Automatically manage signing: Checked</li>
  <li>Team: My Name (Personal Team)</li>
  <li>Provisioning Profile: None Required</li>
  <li>Signing Cert: Development</li>
  </ul>
  <p>What am I doing wrong?</p>
