title: React Native Boilerplate failing on iOS
body: <p>Why won't this work?? I'd appreciate any help...</p>
  <p>I started my React Native project by using the commands</p>
  <pre><code>npx react-native init ProjectName
  npx react-native start
  npx react-native run-ios
  </code></pre>
  <p>I would think this should work out of the box since I haven't changed anything in the boilerplate but I run into this error (just the tail of the logs since it is very long):</p>

  <p>I have googled this error and I have found some fixes/workarounds but I'm wondering: <strong>how can I fix this for good so I don't run into this issue every time I start a new project (eg is there something I need to update)?</strong></p>
