Swift-DocC is a documentation compiler for Swift frameworks and packages aimed at making it easy to write and publish great developer documentation

For an example of Swift-DocC in action, check out Much of Apple's developer documentation, from Reference documentation to Tutorials, and long-form content is built using Swift-DocC.

To learn more about the essentials of this tool refer to the user documentation.

Swift-DocC is being actively developed. For more information about the Swift-DocC project, see the introductory blog post here.

Getting Started with DocC

docc is the command line interface (CLI) for Swift-DocC and provides support for generating and previewing documentation.

There are multiple ways you can make use of DocC depending on your use case:

1. For documenting packages via SwiftPM:

If you want to generate documentation for your Swift package we recommend using the Swift-DocC Plugin. Please refer to the Plugin's documentation to get started with building, previewing, and publishing your documentation to your website or GitHub Pages.

2. For standalone documentation:

If you have Xcode installed, it's recommended to generate documentation using the xcrun command. You can get DocC working by invoking xcrun docc in your terminal.

Swift-DocC is also included in the Swift toolchain for both macOS and Linux.

To see instructions on how to use DocC from the CLI run

docc --help

3. For documenting apps, frameworks, and packages using Xcode:

If you want to generate an API reference for your project you can use DocC via Xcode. Please refer to the Xcode documentation to learn the essentials of how to get started.

Writing and Publishing Documentation with Swift-DocC

If you want to learn how to write and format your documentation please refer to Formatting Your Documentation Content. For publishing go to Distributing Documentation to Other Developers.

To learn more about how Swift-DocC works internally please see


Swift-DocC's CLI tool (docc) is integrated into the Swift toolchain and follows the Swift compiler's versioning scheme.

The SwiftDocC library is versioned separately from docc. SwiftDocC is under active development and source stability is not guaranteed.
