Answer 1

Try cleaning up the build folder and deleting DerivedData folder which clears the build cache. But the main reason is that you haven't set the bundle ID for the app. Assuming you followed the link and made sure that you have one, then usually the build being cached is the issue.

Answer 2

I think there are 2 possible causes:
1) At some point there is some other error that is blocking the creation of the JS bundle.
Check the entire log of the build attempt carefully.
2) The bundle is generated at the incorrect path or using the incorrect index.js file.
