Hello,
If you are either contributing to DocC or working on a project that depends on and imports SwiftDocC as a framework, then this information is relevant to you.
We are planning on updating the swift-tools-version to 6.1 and the supported platform versions to macOS 13/iOS 16 (from 2022) for the main branch of DocC, meaning that the first release it will apply to is the future 6.3 release.
This update only applies to DocC itself, not SymbolKit or Swift Markdown or any of the other packaged that DocC depends on which we know that more people are using in their projects.
It also doesn’t apply to the DocC Plugin meaning that it doesn’t impact your project’s ability to build your documentation using swift package generate-documentation with future Swift versions.
We do this so that we can gradually start adopting Swift Testing and Swift features like Concurrency, Regex, and more. For contributors, we will have separate follow-up pull requests to update DocC’s contributor documentation with more information about our plans to incrementally adopt certain language features.
