steps:

- run: swift test

Specify Swift Version with ".swift-version" file.

steps:
- uses: actions/checkout@v7
- uses: YOCKOW/Action-setup-swift@v1
  with:
    swift-package-directory: "./my-swift-package" # Default is "."
    # The content of ".swift-version" will be used to specify the version
    # when `swift-version` input is lacked.
    # Error occurs if ".swift-version" file is not found.

Use swiftly.

You can use swiftly to install Swift passing 'swiftly' to swift-installer input.

    swift-installer: swiftly
    swift-version: "DEVELOPMENT-SNAPSHOT-2026-08-21-a" # This value is passed to swiftly without modification.
    # Other values are also available such as:
    #    "latest"
    #    "main-snapshot"
    #    "6.4.x-snapshot"
