React Native fetch() Network Request Failed

Question

When I create a brand new project using react-native init (RN version 0.29.1) and put a fetch in the render method to the public facebook demo movie API, it throws a Network Request Failed. There is a very useless stack trace and I can't debug network requests in the chrome console. Here is the fetch I'm sending:

fetch('http://facebook.github.io/react-native/movies.json')
      .then((response) => response.json())
      .then((responseJson) => {
        return responseJson.movies;
      })
      .catch((error) => {
        console.error(error);
      });

The problem here is that iOS does not allow HTTP requests by default, only HTTPS. If you want to enable HTTP requests add this to your info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>
