React Native 0.47.1: Hot reload is not reflecting code changes on MacOS : <p>I'm trying to get hot reload working with my React Native project. The packager shows the message <code>Bundling index.ios.js ... [hmr enabled]</code> and when I make a change, i see the <code>Hot reloading...</code> message flash on the device so I'm confident that the change is being detected.  However, the actual screen is not reflecting the code changes. Live reload works fine.</p>

<p>I've reinstalled the node modules and reset/uninstalled/reinstalled watchman. Nothing seems to have any effect.</p>

<p>What else should I be trying? How do I figure out why the screen isn't being updated? </p>
