title: How to use OSX 10.14 SDK on Xcode 11?
body: <p>I have a project being developed on Xcode 10.2.1 which uses the (32-bit) QTKit framework, specifically QTMovieModernizer.  The project deploys on OSX 10.14.6.</p>
  
  <p>On Xcode 11, this fails (which is somewhat expected):</p>
  
  <pre><code>#import &lt;QTKit/QTMovieModernizer.h&gt;
  </code></pre>
  
  <p><strong>How to I get Xcode 11.x to eschew the MacOSX 10.15 SDK and use the 10.14 SDK instead?</strong></p>
  
  <p>Previously, subbing in SDK's was an easier task, but I don't see the option any longer. I guess I'm okay with continuing with Xcode 10.x for now.</p>
