Swiftui Parity Components

SwiftUI Parity Components

Use this workflow to add high-signal SwiftUI parity components and prove they render correctly in Raven's browser demo.

1. Build a Deterministic Gap List

Run the parity report first to avoid guesswork.

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

Review:

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

Select a small, focused set of missing component APIs (typically 2-4) that are actionable in Raven.

2. Confirm Existing Raven Coverage

Search Raven sources before coding:

rg "struct .*: View|public struct|public func|public var" Sources/Raven

Check for:

• Missing component types
• Signature mismatches (labels, defaults, generic constraints)
• Modifier behavior discrepancies
• Availability or actor-isolation mismatches

3. Implement Components and Runtime Wiring

Add/update APIs under Sources/Raven/** and keep behavior aligned with existing rendering architecture.

Guardrails:

• Follow Swift 6.2 concurrency-safe patterns (@MainActor, @Sendable closures where needed)
• Keep APIs source-compatible with SwiftUI intent where practical
• Reuse existing Raven patterns for VNode/DOM rendering and event plumbing
• Add succinct comments only where behavior is non-obvious

4. Add Demo Usage in TodoApp

Render each new parity component in Examples/TodoApp so browser validation is concrete.

Typical locations:

• Examples/TodoApp/Sources/**
• existing screens or a temporary parity preview section

Ensure new UI is visible without extra setup.

5. Build and Serve the WASM Example

Use the example directory to avoid unrelated workspace failures.

cd Examples/TodoApp
swift build --swift-sdk swift-6.2.3-RELEASE_wasm
swiftly run swift run raven dev --input Examples/TodoApp

If swiftly is unavailable, document the blocker and use the closest working local command.

6. Validate in Browser with Playwright (Light and Dark)

Use Playwright checks against the local dev URL:

• confirm page loads
• confirm each new component is visible and interactive as applicable
• capture dark mode verification (toggle app/theme control if present, otherwise emulate dark scheme)
• inspect console for runtime errors

Record what was validated and any limitations.

7. Catch Nearby Discrepancies

While touching related files, fix small SwiftUI parity inconsistencies discovered nearby (naming, signatures, defaults, obvious rendering bugs).

Do not broaden scope into unrelated refactors.

8. Branch and PR

Create a branch name prefixed with codex/ that reflects added components.

Example:

• codex/add-label-toggle-parity-components

Then:

1. Commit focused changes.
2. Push branch.
3. Open PR with:
   • components added/fixed
   • TodoApp demo updates
   • build command used
   • browser validation summary (light + dark mode)
   • any known gaps/follow-ups

Definition of Done

Consider the task complete only when all are true:

• Selected parity components are implemented or mismatches fixed
• TodoApp renders the new APIs in browser
• Validation covered light and dark mode
• No new console/runtime errors in tested path
• Branch and PR are created with reproducible notes
