Swift Package Manager error

[marcheimendinger]

When using SPM to get the library in Xcode I got this error :

I fixed it by not specifying a version number for the package but by directly pulling the master branch. It would be better to get it working with versions numbers (for example 3.0.0 < 4.0.0).

It's because tagged version does not contain the simple header // swift-tools-version:5.0 in the Package.swift file. The header is required by swift package manager. The code at branch master does contain the header, which is why it works. See https://www.swiftbysundell.com/articles/managing-dependencies-using-the-swift-package-manager/ Simple fix for any maintainer is update the code at latest version tag to make it work with the default Swift Package Manager versioning approach.
