SwiftUI API Gap

Overview

Use this skill to keep Raven's SwiftUI parity tracking deterministic, actionable, and automated.

Primary implementation files:

• Scripts/swiftui_api_gap_report.py
• .github/workflows/swiftui-api-gap-report.yml
• Documentation/SwiftUI-API-Gap-Automation.md

Primary artifact:

• Reports/swiftui-api-gap/gap_report.md

Workflow

1. Run report generation.

Scripts/swiftui_api_gap_report.py --repo-root . --output-dir Reports/swiftui-api-gap

2. Validate outputs exist.

ls -lh Reports/swiftui-api-gap

3. Check report quality quickly.

• Confirm summary section has counts and coverage.
• Confirm named APIs are separate from operator-like overloads.
• Confirm constructor coverage is owner-qualified (Type.init) and not globally skipped.

4. If asked to improve actionability, prioritize:

• Owner-qualified matching for members (Type.func, Type.var, Type.init).
• Noise separation for operator-like signatures.
• Stable high-signal lists for components/modifiers.
• Clear markdown sections that humans can triage.

Automation

Weekly workflow:

• .github/workflows/swiftui-api-gap-report.yml
• Runs Monday via cron.
• Uses macOS runner compatible with Swift/Xcode tooling.
• Uploads artifact bundle.
• Opens/updates PR with refreshed report.

When editing automation:

1. Keep Reports/swiftui-api-gap/gap_report.md in add-paths for PR commits.
2. Keep workflow permissions at least:
   • contents: write
   • pull-requests: write
3. Keep workflow_dispatch so maintainers can run immediately.

Matching Rules

Use these rules unless user asks to change methodology:

• Source of truth: swift-api-digester against Apple SwiftUI module.
• Build SwiftUI inventory from digester output.
• Build Raven inventory from public declarations under Sources/Raven/**/*.swift.
• Match by owner-qualified member names when possible.
• Keep constructors scored by owner (Type.init) unless upgraded to full signature matching.
• Keep operator overloads summarized separately from named actionable APIs.

Troubleshooting

• If skill tooling scripts fail with missing yaml, use repo venv:

venv/bin/python -m pip install pyyaml

• If report looks noisy, inspect:

  • missing.operator_like in gap_report.json
  • owner context fields in high-signal sections

• If workflow cannot be triggered remotely, ensure workflow file is committed to default branch first.
