title: Xcode 12 Beta - Cannot find simulator runtime
body: <p>I have installed Xcode 12 beta 2. I tried to run our xamarin project through Jenkins on Mac OS Catalina. It fails with the below error. When I build the same project from Mac Visual studio, it succeeded without any error.</p>
  <pre><code>SplashViewController.storyboard : error :
   iOS 14.0 (14.0 - 18A5319g) - com.apple.CoreSimulator.SimRuntime.iOS-14-0 (unavailable, failed to open liblaunchsim.dylib) ==&gt; not available:
    Error Domain=com.apple.CoreSimulator.SimError Code=401 &quot;The iOS 14.0 simulator runtime is not available.&quot;

  </code></pre>
  <p>I also did <code>xcrun simctl list</code> to view the available runtime simulators for Xcode 12 beta.
  It shows the below list but fails while building.</p>
  <p>== Runtimes ==</p>
  <pre><code>iOS 14.0 (14.0 - 18A5319g) -
  com.apple.CoreSimulator.SimRuntime.iOS-14-0
  tvOS 14.0 (14.0 - 18J5331g) -
  com.apple.CoreSimulator.SimRuntime.tvOS-14-0
  watchOS 7.0 (7.0 - 18R5327h) -
  com.apple.CoreSimulator.SimRuntime.watchOS-7-0
  </code></pre>
  <p>== Devices ==</p>
  <p>When I opened Xcode Settings and clicked to <strong>Components -&gt; Simulator</strong> I do not see <strong>iOS 14</strong> in the list:</p>
  <p>Can anyone help me to resolve this?</p>
