issue with swift package manager - missing manifest

[qalvapps]

Xcode 12.5 and Xcode 13.1

attempting to add package :

the manifest is missing a Swift tools version specification; consider prepending to the manifest '// swift-tools-version:5.5.0' to specify the current Swift toolchain version as the lowest Swift version supported by the project; if such a specification already exists, consider moving it to the top of the manifest, or prepending it with '//' to help Swift Package Manager find it
