Swift team announces that The Swift Programming Language is now published using Swift-DocC documentation compiler.

This is a significant milestone for the DocC documentation tool.

This is a major step for the book. It was first open-sourced in August 2022 and since then, we’ve merged over 50 pull requests as we converted to DocC. We also made enhancements to DocC based on what we learned working on the book, like adding control over automatic see-also sections and new on-page navigation. Other DocC content that guides developers through a linear narrative, like the documentation for large or complex packages, can also take advantage of these enhancements.

Swift team

DocC project is open-source and open for contribution.
