This issue take me some days to fixed. I got this issue when run the build on travis-ci. Here is my fix:

Add this line to scripts in your package.json file.

"build:ios": "react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios'"

Now your can run the command to generate main.jsbundle. yarn build:ios or npm run build:ios

Open the Xcode > Select project target > add main.jsbundle to Copy Bundle Resource in Build Phases. (image below).
