title: Cannot build project with Xcode 12.0 beta 5
body: <p>I downloaded Xcode 12.0 beta 5 and I'm trying to build my project, but I received the following error:</p>
  <pre><code>&lt;unknown&gt;:0: error: unable to load standard library for target 'arm64-apple-ios9.0'
  </code></pre>
  <p>I tried searching online for solutions, but none of what I found helped me to solve this error. I found <a href="https://stackoverflow.com/questions/51558933/error-unable-to-load-standard-library-for-target-arm64-apple-ios10-0-simulator">this thread</a> on SO but none of the proposed solutions worked for me.</p>
  <p>I think it's an error related to simulator. In fact, the project builds correctly with generic device and on a real device.</p>
