This repo host a Swift Package with the implementation of the abstract KMP module located at: https://github.com/pablichjenkov/macao-marketplace/blob/dev/auth-firebase/src/iosMain/kotlin/com/macaosoftware/plugin/account/FirebaseAuthKmpWrapper.kt
This package is a wrapper of the Firebase Authorization swift API defined in above link.

Kotlin can't talk to swift directly but can consume a Kotlin interface which implementation is made with swift. This project is a proof of concept on how to host an SPM package in a different repo than composeApp. To consume this package from a KMP project, there are some requirements to be met:

1. The KMP project umbrella module has to produce a framework named ComposeApp.

   As of now, by convention, KMP should only export 1 framework to the iOS integration App, so we agree on the swift module to import ComposeApp as the provider of the KMP interfaces.

2. The KMP abstraction module has to be included in gradle using api(...) and not using implementation(...).

   This is because we have to export that module and only dependencies consumed as api(...) can be exported to the umbrella module.

That is all you need.
