title: AppCode editor does not respect multiple target, Swift Compiler Flags
body: <p>When I switch to build any target that is not the first target. The code editor does not recognize the target change.</p>
  
  <h2>So any code</h2>
  
  <pre><code>#if &lt;other target&gt;
  ...
  #endif
  </code></pre>
  
  <p>...is not recognized by appCode editor. When building, works as expected isolating code build for each target.</p>
  
  <h2>Setup: Target Configuration 'Other Swift Flags'</h2>
  
  <pre><code>-D&lt;other target&gt;
  </code></pre>
  
  <p>In Xcode changing the build target changes what code the editor recognizes. Is there some other place to change this that I can't find? Is this a bug or a limitation?</p>
