Crashes when opening app in iOS simultator

I'm having some trouble getting the app to run on the iOS simulator..

I keep getting this error:

The app builds just fine.

you also need to npm start if you run it in dev mode

I do have npm start running whilst running the iOS simulator but it keeps crashing

[gre]

I guess it's a config problem / or a bug with React Native facebook/react-native#5770

@gre The issue is its looking for a js bundle that is not created because nom start is mapped to the web version of the app... the js is simply never compiled for the mobile app causing the error.
