# SwiftUI Expert Skill
## Operating Rules
- Consult `references/latest-apis.md` at the start of every task to avoid deprecated APIs
- Prefer native SwiftUI APIs over UIKit/AppKit bridging unless bridging is necessary
- Focus on correctness and performance; do not enforce specific architectures (MVVM, VIPER, etc.)
- Encourage separating business logic from views for testability without mandating how
- Follow Apple's Human Interface Guidelines and API design patterns
- Only adopt Liquid Glass when explicitly requested by the user (see `references/liquid-glass.md`)
- Present performance optimizations as suggestions, not requirements
- Use `#available` gating with sensible fallbacks for version-specific APIs
## Task Workflow
### Review existing SwiftUI code
- Read the code under review and identify which topics apply
- Flag deprecated APIs (compare against `references/latest-apis.md`)
- Run the Topic Router below for each relevant topic
- Validate `#available` gating and fallback paths for iOS 26+ features
### Improve existing SwiftUI code
- Audit current implementation against the Topic Router topics
- Replace deprecated APIs with modern equivalents from `references/latest-apis.md`
- Refactor hot paths to reduce unnecessary state updates
- Extract complex view bodies into separate subviews
- Suggest image downsampling when `UIImage(data:)` is encountered (optional optimization, see `references/image-optimization.md`)
### Implement new SwiftUI feature
- Design data flow first: identify owned vs injected state
- Structure views for optimal diffing (extract subviews early)
- Apply correct animation patterns (implicit vs explicit, transitions)
- Use `Button` for all tappable elements; add accessibility grouping and labels
- Gate version-specific APIs with `#available` and provide fallbacks
### Record a new Instruments trace
Trigger when the user asks to "record a trace", "profile the app", "capture a session", etc. Full reference: `references/trace-recording.md`.
1. **Confirm target** — attach to a running app, launch an app, or record all processes? If the user didn't say, ask. List connected devices when useful:
```bash
python3 "${SKILL_DIR}/scripts/record_trace.py" --list-devices
```
2. **Pick a template based on target kind** — the `SwiftUI` template populates the SwiftUI lane on any **real device**: a physical iOS/iPadOS device **or the host Mac**. The only exception is the **iOS Simulator**, where the SwiftUI lane comes back empty — switch to `--template "Time Profiler"` in that case (still gives Time Profiler + Hangs + Animation Hitches). Always check `--list-devices`: `simulators` kind → `Time Profiler`; `devices` kind (real devices and the host Mac) → default `SwiftUI`. Full decision table in `references/trace-recording.md`.
3. **Start the recording**. For agent-driven sessions where the user says "I'll tell you when I'm done", start in the background and use a stop-file:
```bash
python3 "${SKILL_DIR}/scripts/record_trace.py" \
--device "<name|udid>" --attach "<AppName>" \
--stop-file /tmp/stop-trace --output ~/Desktop/session.trace
```
For interactive sessions, just tell the user to press Ctrl+C when done.
4. **Signal stop** — when the user says they've finished exercising the app, `touch /tmp/stop-trace`. The script cleanly SIGINTs xctrace and waits up to 60s for finalisation.
5. **Analyse** the resulting trace (flow into the "Trace-driven improvement" workflow below).
### Trace-driven improvement (Instruments `.trace` provided)
Trigger whenever the user's request references a `.trace` file. A target SwiftUI source file is **optional** — if given, cite specific lines; if not, recommend where to look based on view names and symbols the trace already reveals.
Full reference: `references/trace-analysis.md`. Summary of the composition pattern:
1. **Scope the analysis.** Ask yourself: does the user want the whole trace, or a slice?
- "focus on X / after X / between X and Y / during X" → **resolve to a window first** (see step 2).
- No scoping cue → analyse the whole trace.
2. **Resolve a window (only if the user scoped).** The parser exposes two discovery modes:
```bash
# Find a log that marks the start/end of the region of interest:
python3 "${SKILL_DIR}/scripts/analyze_trace.py" --trace <path> \
--list-logs --log-message-contains "loaded feed" --log-limit 5
# Or list os_signpost intervals (paired begin/end), filterable by name:
python3 "${SKILL_DIR}/scripts/analyze_trace.py" --trace <path> \
--list-signposts --signpost-name-contains "ImageDecode"
```
Both modes accept `--window START_MS:END_MS` to scope discovery. Pick the `time_ms` (for logs) or `start_ms`/`end_ms` (for signposts) that match the user's description. Build a window like `--window 10400:11700`.
3. **Run the main analysis** (with or without `--window`):
```bash
python3 "${SKILL_DIR}/scripts/analyze_trace.py" --trace <path> \
--json-only --top 10 [--window START_MS:END_MS]
```
4. **Interpret with `references/trace-analysis.md`** — key diagnostics:
- `main_running_coverage_pct` inside each correlation (<25% = blocked; ≥75% = CPU-bound).
- `swiftui-causes.top_sources` reveals *why* updates keep happening — high-edge-count sources like `UserDefaultObserver.send()` or wide `EnvironmentWriter` entries are structural invalidation bugs. Fixing one often collapses many downstream hot views.
5. **When a specific view shows as expensive, ask who's invalidating it.** Use `--fanin-for "<view name>"` to get the ranked list of source nodes driving the updates.
6. **Optionally ground in source.** If the user pointed at a file, read it and match view names / user-code symbols against identifiers there. If not, recommend which files to open based on the view names SwiftUI reported.
7. **Return a prioritised plan.** Cite evidence (coverage %, hot symbol, overlapping view, log timestamp, cause-graph edges) and route each recommendation to a Topic Router reference.
8. Only edit code if the user asked for edits.

## Correctness Checklist
These are hard rules -- violations are always bugs:
- [ ] `@State` properties are `private`
- [ ] `@Binding` only where a child modifies parent state
- [ ] Passed values never declared as `@State` or `@StateObject` (they ignore updates)
- [ ] `@StateObject` for view-owned objects; `@ObservedObject` for injected
- [ ] iOS 17+: `@State` with `@Observable`; `@Bindable` for injected observables needing bindings
- [ ] `ForEach` uses stable identity (never `.indices`/`\.offset`; id outlives the view and isn't derived from mutable content)
- [ ] Constant number of views per `ForEach` element; `List` rows are unary
- [ ] No closures stored in custom `@Environment`/`@FocusedValue` keys
- [ ] Custom `@Entry` default values are stable (no `Model()`/`Date()`/`UUID()` expressions)
- [ ] `.animation(_:value:)` always includes the `value` parameter
- [ ] `@FocusState` properties are `private`
- [ ] No redundant `@FocusState` writes inside tap gesture handlers on `.focusable()` views
- [ ] iOS 26+ APIs gated with `#available` and fallback provided
- [ ] `import Charts` present in files using chart types
- [ ] Previews use self-contained mock data; no dependency on live services or network
