title: Xamarin.iOS versions mismatch 11.14
body: <p>I am on current Visual Studio Version 15.8.4 which contain Xamarin.iOS 11.14.0.13. Today I updated my Visual Studio for Mac and automatically updated Xamarin.iOS to version 12.0.0.15 (based on he Xcode 10 final release) which is not compatible. I get the following error:</p>
  <blockquote>
  <p><strong>Xamarin.iOS versions mismatch</strong></p>
  <p>The Xamarin.iOS SDK version installed on
  Max is not compatible with this version of Visual Studio. Would you
  like us to install Xamarin.iOS '11.14' for you? This will overwrite
  any existing Xamarin.iOS installation on your Mac.</p>
  </blockquote>
  <p>When I click 'Install' then the following error occurs:</p>
  <blockquote>
  <p><strong>Error</strong></p>
  <p>There were problems installing Xamarin.iOS '11.14'. Please try
  again and if the problem persists, try installing directly on the Mac
  and connect again.</p>
  </blockquote>
  <p>On the mac I chose <strong>Update channel: Stable</strong>. I also tried the other channels withoud success. I am not able to install version 11.14 at all at the moment.</p>
  <p>Is my only option to wait until they fix that version mismatch?</p>
