title: Swift import CoreGraphics.CGBase VS. import CoreGraphics causes LLDB malfunctioning
body: <p>I have some swift code files in my Objective-C based project.</p>
  
  <p>I can compile it and they are playing well with each other.</p>
  
  <p>The swift code does</p>
  
  <p><code>import CoreGraphics.CGBase</code></p>
  
  <p>However, when I was debugging the swift code,
  I will get:</p>
  
  <pre><code>error: Error in auto-import:
  failed to get module 'CGBase' from AST context
  </code></pre>
  
  <p>If I replace <code>import CoreGraphics.CGBase</code> to <code>import CoreGraphics</code>, issue is gone.</p>
  
  <p>Can anyone explain what the side effect if I use import CoreGraphics? And is this a bug for LLDB or xcode?</p>
