Who it's for

For iOS and Flutter teams whose TestFlight and App Store builds are archived and uploaded from GitHub Actions macOS runners.

What breaks, and when

Since 28 Apr 2026 App Store Connect requires Xcode 26 with an iOS 26 SDK; macos-15 defaults to Xcode 16.4, and GitHub retires macos-14 on 2 Nov 2026.

What it printed on the bundled example

What you get

• A scanner Claude runs over every workflow file - not a guess from memory
• 10 dated rules: macos-14/13 labels, macos-15 default Xcode 16.4, pins below 26, -sdk below 26, iOS target below 13
• One line per Apple build job: runner → Xcode → accepted or rejected
• Claude proposes the edits and applies them only after you say yes; exit 1 in CI on any error

FAQ

What is a Claude Code skill?

A folder with a SKILL.md and scripts that Claude Code loads when your request matches it. You ask in plain words and Claude runs the scanner the skill carries.

How is this different from asking Claude without the skill?

The skill carries a dated rule table and a scanner that reads every file, so Claude quotes the exact date and line instead of answering from memory.

Does it send my code anywhere?

Reads workflow YAML only; it does not run xcodebuild, read .xcodeproj settings or contact GitHub or Apple.

How do I install it?

Unzip into ~/.claude/skills/ (all projects) or your-repo/.claude/skills/ (one repo), then ask Claude Code: "Our iOS release runs on GitHub Actions and I'm not sure every job archives with Xcode 26 now that App Store Connect requires it.
