composable-architecture

SKILL.md

TCA provides architecture for building complex, testable features through composable reducers, centralized state management, and side effect handling. The core principle: predictable state evolution with clear dependencies and testable effects.

ALWAYS load reference files if there is even a small chance the content may be required. It's better to have the context than to miss a pattern or make a mistake.

| Reducer Structure | Creating new reducers, setting up @Reducer, State, Action, or @ViewAction | | Views - Binding | Using @Bindable, two-way bindings, store.send(), or .onAppear/.task | | Views - Composition | Using ForEach with stores, scoping to child features, or optional children |

在使用 TCA（可組合架構）構建功能、構造化簡器、管理狀態、處理效果、導航或測試 TCA 功能時使用。涵蓋 @Reducer、Store、Effect、TestStore、reducer 組合和 TCA 模式。 來源：johnrogers/claude-swift-engineering。
