swiftui-patterns
SwiftUI architecture patterns, state management with @Observable, view composition, navigation, performance optimization, and modern iOS/macOS UI best practices.
npx skills add mturac/everything-openai-codex --skill swiftui-patterns --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# SwiftUI Patterns Modern SwiftUI patterns for building declarative, performant user interfaces on Apple platforms. Covers the Observation framework, view composition, type-safe navigation, and performance optimization. ## When to Activate - Building SwiftUI views and managing state (`@State`, `@Observable`, `@Binding`) - Designing navigation flows with `NavigationStack` - Structuring view models and data flow - Optimizing rendering performance for lists and complex layouts - Working with environment values and dependency injection in SwiftUI ## State Management ### Property Wrapper Selection Choose the simplest wrapper that fits: | Wrapper | Use Case | |---------|----------| | `@State` | View-local value types (toggles, form fields, sheet presentation) | | `@Binding` | Two-way reference to parent's `@State` | | `@Observable` class + `@State` | Owned model with multiple properties | | `@Observable` class (no wrapper) | Read-only reference passed from parent | | `@Bindable` | Two-way binding to an `@Observable` property | | `@Environment` | Shared dependencies injected via `.environment()` | ### @Observable ViewModel Use `@Observable` (not `ObservableObject`) — it tracks property-le

What does the swiftui-patterns skill do?
SwiftUI architecture patterns, state management with @Observable, view composition, navigation, performance optimization, and modern iOS/macOS UI best practices.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill swiftui-patterns --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
