Swift-DocC Plugin

The Swift-DocC plugin is a Swift Package Manager command plugin that supports building documentation for SwiftPM libraries and executables.

Usage

Please see the plugin's documentation for more detailed usage instructions.

Adding the Swift-DocC Plugin as a Dependency

To use the Swift-DocC plugin with your package, first add it as a dependency:

let package = Package(
    // name, platforms, products, etc.
    dependencies: [
        // other dependencies
        .package(url: "https://github.com/apple/swift-docc-plugin", from: "1.1.0"),
    ],
    targets: [
        // targets
    ]
)

Swift 5.6 is required in order to run the plugin.

Converting Documentation

You can then invoke the plugin from the root of your repository like so:

swift package generate-documentation

This will generate documentation for all compatible targets defined in your package and its dependencies and print the location of the resulting DocC archives.

If you'd like to generate documentation for a specific target and output that to a specific directory, you can do something like the following:

swift package --allow-writing-to-directory ./docs \
    generate-documentation --target MyFramework --output-path ./docs

Notice that the output path must also be passed to SwiftPM via the --allow-writing-to-directory option. Otherwise SwiftPM will throw an error as it's a sandbox violation for a plugin to write to a package directory without explicit permission.

Any flag passed after the generate-documentation plugin invocation is passed along to the docc command-line tool. For example, to take advantage of Swift-DocC's new support for hosting in static environments like GitHub Pages, you could run the following:

swift package --allow-writing-to-directory ./docs \
    generate-documentation --target MyFramework --output-path ./docs \
    --transform-for-static-hosting --hosting-base-path MyFramework

Previewing Documentation

The Swift-DocC plugin also supports previewing documentation with a local web server. However, unlike converting documentation, previewing is limited to a single target a time.

To preview documentation for the MyFramework target, you could run the following:

swift package --disable-sandbox preview-documentation --target MyFramework

To preview documentation for a product defined by one of your package's dependencies, you could run the following:

swift package --disable-sandbox preview-documentation --product OtherFramework

Hosting Documentation

For details on how to best build documentation for hosting online and a specific tutorial for publishing to GitHub Pages, please see the plugin's documentation.
