[CritiqalPete]

The issue appears during buildtime on XCode:
...Build/Products/Release-iphoneos/America Scores Attendance.app/main.jsbundle does not exist. This must be a bug with'
Searching shows this being a react-native issue that Facebook says is linked to an XCode build update:

This operation worked for me and saved my week :)

Add this to the package.json - scripts

"bundle:ios": "node ./node_modules/react-native/local-cli/cli.js bundle --platform ios --entry-file index.js --bundle-output ios/**yourAppName**/main.jsbundle --dev=false --verbose"

Now you can run the command to generate main.jsbundle:

npx yarn bundle:ios

Open the Xcode -> Select project target -> add main.jsbundle to Copy Bundle Resource in Build Phases

Archive again.
