title: Could not build module
body: <p>After Xcode update to v. 5.0.2 i can't build my app for iOS 6.0 target.
  I can build only for iOS 7.0</p>
  
  <p>I get many errors:</p>
  
  <pre><code>Could not build module CoreFoundation
  Could not build module Darwin
  Cyclic dependency in module Darwin: Darwin -&gt; Foundation -&gt; CoreFoundation -&gt; Darwin
  Could not build module Foundation
  </code></pre>
  
  <p>Interesting thing, is that before the update it was possible to compile the app for iOS 6.0, <strong>BUT</strong> I had the same errors when trying to compile app for iPhone 4/4S</p>
  
  <p>PS. Build Settings - armv7, armv7s. <strong>Without arm64.</strong></p>
