I tried to manually bundle the project with --dev=false 

react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'

and I got this error output

Changing --dev=false to --dev=true, the buid success with these output

I have tried
- clean and rebuild
- remove node_modules and reinstall
- clean Derived folder, restart Xcode, but none of them solve the issue.

It seems like this is the main issues.

I struggle a few days to figure the cause of node_modules/rx/dist/rx.all.js: Cannot convert object to primitive value error by comment all code and uncomment one by one.

The thing is that VS Code auto import unknown library when I coincidently press Enter after autocompletion popup. It is

import { AsyncSubject } from 'rx';

After removing the import statement, I successfully build the project in Release mode.

This kind of error does not throw exception when running as Dev mode :(, except while building for Release.
