SwiftGen plugin for SPM

SwiftGenPlugin

SwiftGen code generation for Swift packages that works on any machine. No installation required, simply add the package to your Package.swift's dependencies:

  dependencies: [
    .package(url: "https://github.com/SwiftGen/SwiftGenPlugin", from: "6.6.0")
  ]

Using it as a (pre-)build tool

Adding SwiftGen as a prebuild tool will execute it and generate your files before each build.

Add to Package.swift

After adding the dependency to your Package.swift, include the SwiftGenPlugin plugin in any targets for which you would like it to run.

  targets: [
    .target(
      name: "YourTargetName",
      dependencies: [],
      plugins: [
        .plugin(name: "SwiftGenPlugin", package: "SwiftGenPlugin")
      ]
    )
  ]

Add a SwiftGen config

Add a swiftgen.yml file to your project following the configuration file format, and prefix each of your output paths with ${DERIVED_SOURCES_DIR}/. Or set this globally in your configuration by setting the output_dir to that value.

Take a look at this repository's swiftgen.yml for an example.

Supporting Multiple Targets

Each time the plugin is invoked it will look for a swiftgen.yml configuration file in 2 places:

1. The root of your package (same folder as Package.swift).
2. Your target's folder, for example Sources/MyExample.

It will invoke SwiftGen for each found configuration file, so you could choose either option, or combine both. This can be useful if you need some target-specific configuration and some shared configuration, without repeating yourself.

Do note that the paths (to resources) in a configuration will need to change depending on where the configuration is located:

1. Root configurations will need the full path to resources, such as Sources/MyExample/Resources/Localizable.strings. Or set the config's input_dir to Sources/MyExample/Resources. See an example of a top-level configuration.
2. Target configurations will need the relative path to resources, such as Resources/Localizable.strings. Or set the config's input_dir to Resources. See an example of a target specific configuration.

Using it as a command

You can manually invoke SwiftGen using the following command:

swift package --allow-writing-to-package-directory generate-code-for-resources

The command will automatically search for swiftgen.yml configuration files in each of your targets' (or top-level) folder, and invoke SwiftGen for them.

If you want to manually provide the configuration file and other settings, pass them along as extra arguments:

swift package --allow-writing-to-package-directory generate-code-for-resources --config MyConfig.yml
