SwiftUI Core
SwiftUI fundamentals shared across all Apple platforms.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze existing SwiftUI patterns
- fuse-ai-pilot:research-expert - Verify latest SwiftUI docs via Context7/Exa
- mcp__apple-docs__search_apple_docs - Check SwiftUI view patterns
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Building SwiftUI views and components
- Implementing navigation (NavigationStack, SplitView)
- Data persistence with SwiftData
- State management (@State, @Observable)
- Custom view modifiers and layouts
Why SwiftUI Core
| Feature | Benefit | |---------|---------| | Declarative UI | Less code, automatic updates | | Cross-platform | Same code for iOS/macOS/watchOS/visionOS | | @Observable | Simple reactive state | | SwiftData | Modern persistence with minimal code |
Key Concepts
Views & Modifiers
Composable UI building blocks. Extract subviews at 30+ lines.
Navigation
NavigationStack for stack-based, NavigationSplitView for multi-column.
SwiftData
Modern persistence with @Model. Replaces Core Data for most use cases.
State Management
@State for local, @Observable for shared, @Environment for injection.
Reference Guide
| Need | Reference | |------|-----------| | Views, modifiers, layouts | views-modifiers.md | | NavigationStack, deep linking | navigation.md | | SwiftData, @Query, CloudKit | data-swiftdata.md | | @State, @Observable, Environment | state-management.md | | Liquid Glass all platforms | liquid-glass.md | | Siri, Shortcuts, App Intents | app-intents.md |
Best Practices
- Small views - Extract at 30+ lines
- Composition - Use ViewBuilder and modifiers
- Preview-driven - Always include #Preview
- Semantic colors - Use .primary, .secondary
- Accessibility - Add labels to icons
- Platform adaptation - Check sizeClass for responsive layouts

Logged-in web apps — dashboards, auth flows, settings, onboarding, data tables, command palettes, modals, toasts. Register `product`: density and glance-speed over marketing polish, no hero/CTA-tricks, every data surface covers empty/loading/error explicitly, tables and dataviz follow preattentive-processing rules.

Marketing sites, landing pages, campaign pages — register `brand` (design IS the product). Structure comes from the register's POV + a macrostructure pick, never from copying an inspiration site's section flow. Hero discipline, deviated section order, asymmetric grids, and a silhouette lookalike-test gate before ship.

Token-strategy core — OKLCH color rules, neutral tinting, accent-commitment levels, type scale, 8pt spacing grid, touch targets, and the canonical output format of design-system.md (the file the harness gates on). This is routing step 1 of design-method/SKILL.md — read it before design-web/design-webapp/design-ios/design-android, before picking or auditing a single color/type/spacing value.
