What is missing or inaccurate about the content on this page?
As capacitor is transitioning to use of SPM, is CocoaPods still required for the use of the Firebase SDK ?

If not, please update the documentation

Any updates on this? We have a project built with push-notifications using Cocoapods, and it would be ideal to be able to migrate the same implementation but with SPM.
