title: How do I build a react-native app using Xcode build
body: <p>I created a completely new react-native project using:</p>
  
  <pre><code>react-native init demo
  </code></pre>
  
  <p>After the successful creating I can run it using the react-native cli.</p>
  
  <pre><code>cd demo &amp;&amp; react-native run-ios
  </code></pre>
  
  <p>When I try to open the ios library in Xcode and click on the build button I get the following error:</p>
  
  <blockquote>
    <p>Library not found for -lDoubleConversion</p>
  </blockquote>
  
  <p>Is there a way to build the project using XCode? What could be the reason for my error?</p>
  
  <p>All my packages are updated to the latest versions. (Xcode, react-native, node).</p>
