Swift Package Manager failed

I'm building a swiftUI project for ios and trying to connect a Firebase/FireStore DB to the project using Swift Package Manager and importing; firebase-ios-sdk. In doing so, I get a Package Resolution Failed message with a box and list of all the firebase-ios-sdk that could not be resolved.

I tried deleting the derived data folder content, resetting package caches, resolving the package version, restart Xcode. Nothing worked.

Last night I uninstalled Xcode and re-installing Xcode overnight. Did not work, still the same issue today.

When I import Firebase to the .swiftui file, I get a code error message - No such module 'FirebaseCore'

Swift Package Manager failed
