How can I use Swift Package Manager (SPM) and cocoapods together in one project?

I just tried CocoaPods with SPM on my iOS project and it works fine.
I’m adding Firebase and other Google libs using CocoaPods and the rest using Swift Package Manager.

When adding SPM dependency, put checkmark on your project(s) and not on the Pods project.

Xcode 11.5,
CocoaPods 1.9.3.
