Actions: macOS 14 (Sonoma) is generally available and the `latest` macOS runner image

[github-product-roadmap]

Summary

macOS 14 is now generally available for GitHub-hosted runners. It will also become the latest macOS runner image with workflows migrating from April 2024 through June 2024.

Intended Outcome

Apple developers require the latest version of macOS and Xcode.

How will it work?

Actions workflows using the macos-latest label will incrementally transition from macOS 12 to macOS 14 beginning April 8th 2024 and will conclude before the end of June 2024. This also applies to larger macOS runners, for which the following YAML workflow labels can be used:

• macos-latest-xlarge
• macos-latest-large

jobs:
  build:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v2
      - name: Build
        run: swift build
      - name: Run tests
        run: swift test

To use macOS 14 directly, update your workflows to include runs-on: macos-14, runs-on: macos-14-xlarge, or runs-on: macos-14-large

jobs:
  build:
    runs-on: macos-14
    steps:
      - uses: actions/checkout@v2
      - name: Build
        run: swift build
      - name: Run tests
        run: swift test
