title: Building iOS framework missing architecture armv7s and x86_64 on fat file
body: <p>I'm building my own framework by following the guide on site </p>
  
  <p><a href="http://www.raywenderlich.com/65964/create-a-framework-for-ios" rel="noreferrer">Create a framework for iOS - RayWenderlich</a></p>
  
  <p>It works well, but when I integrate the framework on test project, it catches error as "undefined symbol for architecture arm64". When I check the supported architectures by the command</p>
  
  <pre><code>&lt;myframework&gt;.framework xcrun lipo -info &lt;myframework&gt;
  </code></pre>
  
  <p>it misses 2 architectures armv7s and x86_64</p>
  
  <p>Here is my run script on Aggregate target</p>

  </code></pre>
  
  <p>I suppose the build error when integrating framework to test project causes by the missing architecture when building framework</p>
