title: Error Running React Native App From Terminal (iOS)
body: <p>I am following the tutorial on the official React Native website.</p>
  
  <p>Using the following to build my project:</p>
  
  <pre><code>react-native run-ios
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>Found Xcode project TestProject.xcodeproj
  xcrun: error: unable to find utility "instruments", not a developer   
  tool or in PATH
  
  Command failed: xcrun instruments -s
  xcrun: error: unable to find utility "instruments", not a developer 
  tool or in PATH
  </code></pre>
  
  <p>Although, when I run the app from the .xcodeproj, everything works fine.</p>
  
  <p>Any suggestions?</p>
