Cannot build latest version from master

Before I was using cocoapods so maybe there is something I don't understand re Swift Packages. I get the following errors after trying to compile the project:

after openning the project Swift Package Manager seems to correctly fetch both packages but still not able to build project.

using Macos Catalina 10.15.6 and XCode Version 12.1 (12A7403)

[cdinarte]

On xcode, go to File > Swift Packages > Update to latest package versions, that should fix it.
