The iOS SDK version '...' is not installed, and no newer version was found
<p>I get the error <strong>after updating Xamarin</strong> in Visual Studio which I had to do <strong>after a git pull</strong>.  I have also applied the <strong>Xamarin updates</strong> in Xamarin Studio on my Mac build host.  (Xamarin Studio > Check for updates).</p>

<pre><code>The iOS SDK version '9.2' is not installed, and no newer version was found.
