Building and testing Swift

Source file: content/actions/tutorials/build-and-test-code/swift.md

What part(s) of the article would you like to see updated?

The tutorial's examples have aged and no longer reflect current Swift CI practice:

• Swift versions are several years old. The matrix example uses swift: ["5.2", "5.3"] and the single-version examples use "5.3.3". Swift is now on the 6.x series (current release 6.3).
• swift-actions/setup-swift is pinned to a 2021 commit (65540b95f51493d65f5e59e97dcef9629ddf11bf). The action's current release is v2.4.0 (November 2025). This is the same kind of staleness previously reported in Swift article points to outdated version of setup-swift action #12678.

Proposed changes (the uncontroversial refresh)

1. Update the example Swift versions to current releases.
2. Refresh the swift-actions/setup-swift SHA pin to its current release, keeping the not-certified-by-GitHub notice and SHA-pinning reusables already used on the page.
3. Optionally add a short section showing how to build and test on Linux using the official swift container images (and the swiftlang/swift nightly images), which doesn't require a separate Swift-setup step.

A question before I open a PR

Swift CI today commonly spans more than Ubuntu/macOS swift build — Apple platforms via Xcode, plus Windows, Android, and WebAssembly. Would the team be open to a brief cross-platform section that demonstrates these, including links to community actions (for example compnerd/gha-setup-swift for Windows and skiptools/swift-android-action for Android)?

I'd like to confirm this fits the docs' guidance on mentioning third-party tools before investing in a larger PR. For transparency: one action I might reference, brightdigit/swift-build, is one I maintain, so I'd want any mention to be neutral and in line with how the page already references swift-actions/setup-swift.

Happy to scope the PR to just items 1–2 (or 1–3) if that's preferable.
