title: The code signature version is no longer supported
body: <p>An app signed with a codesign version provided on an older macOS, like Catalina (10.15) will not run on iOS 15 because the lastest version you can install is Xcode 12.4.</p>
  <p>Xcode 12.5 seems to change the behavior of codesigning. When installing you get the error message:</p>
  <blockquote>
  <p>The code signature version is no longer supported</p>
  </blockquote>
  <p>Is there a workaround?</p>
