Summary

  • Xcode 27 runner image is generally available
  • The GitHub-hosted image runs on macOS 27
  • Includes the Xcode 27 toolchain and Apple SDKs
  • Each image supports one major Xcode version rather than targeting a specific OS version

"Xcode 27 runner image generally available" is now the standard for building and testing Apple applications in GitHub Actions. This image, previously in public preview, runs on macOS 27 and includes the Xcode 27 toolchain and Apple SDKs. "Each image supports one major Xcode version rather than targeting a specific operating system version" and is available on Apple Silicon (arm64) runners only, not Intel runners. To view the installed software or report an issue, visit the runner-images repository.

  • GA status: Xcode 27 runner image generally available
  • Runs on macOS 27 with Xcode 27 toolchain and Apple SDKs
  • One major Xcode version per image
  • Apple Silicon (arm64) runners only; Intel not supported
  • Use runs-on labels in workflows to select the image

HOW TO USE THE XCODE 27 RUNNER IMAGE IN GITHUB ACTIONS

To use the image, set your workflow’s runs-on value to one of the labels provided by GitHub for the runner images. If you already use these labels, you don’t need to change your workflows. The image is available on Apple Silicon (arm64) runners only, not Intel runners.

  • Set runs-on in workflow to the appropriate runner label
  • No OS-version targeting beyond the chosen Xcode version

IMPLICATIONS FOR DEVELOPERS AND CI WORKFLOWS

The one-major-Xcode-version-per-image design may reduce coupling to the host OS version, providing clearer expectations for which toolchain is in use. This could help teams align CI configurations with the Xcode version they require, without worrying about the latest macOS version.

  • Potentially clearer toolchain expectations
  • May influence how teams structure their workflow matrices

LIMITATIONS TO CONSIDER

The GA image is arm64-only, meaning Intel-based runners are not available for this image, which may affect workflows that rely on Intel runners or hybrid environments.

  • Arm64-only runners
  • No Intel runner support for this image
