I believe that they are using Semantic Versioning 2.0.0[1] as discussed in the Swift Package Manager Project's Website[2] under "Importing Dependencies": > Given a version number MAJOR.MINOR.PATCH, increment the: > MAJOR version when you make incompatible API changes, > MINOR version when you add functionality in a backwards-compatible manner, and > PATCH version when you make backwards-compatible bug fixes. > Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.
