title: Xcode 12 Beta 2 - unable to load standard library for target 'arm64-apple-ios14.0-simulator'
body: <p>I have just installed Xcode 12 Beta 2. Everytime I build or run it creates the following error:</p>
  <blockquote>
  <p>unable to load standard library for target 'arm64-apple-ios14.0-simulator'</p>
  </blockquote>
  <p>Any idea why that is and what I need to do?</p>
