title: React native: xcode no such file or directory: libreact.a
body: <p>I set up a project in React-Native with react-native init , and open iOS project in Xcode. whenever I tried to build, got the same error</p>
  
  <pre><code> no such file or directory: '/Users/vipinjoshi/Library/Developer/Xcode/DerivedData/AwesomeProject-eopkvbaiswfqmvgpwpyfvelrgrsk/Build/Products/Debug-iphonesimulator/libReact.a'
  </code></pre>
  
  <p>I can't understand what is wrong with the project. I have updated node, watchman, and react-native versions. My Xcode version is 9.2</p>
  
  <p>what I tried: </p>
  
  <p>1) clean and build
  2) Clear Derived data</p>
