If you are debugging bundles you will often want to get the location of where those bundles are on your filesystem. To find them at runtime:
let bundles = Bundle.allBundles
// or in the Xcode console.
po Bundles.allBundles
You can get the file path of them and view them in the finder/terminal.
You can also inspect what localisations are available to you in you bundle:
Bundle.main.localizations
// Or in your module
Bundle.module.localizations
