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（可组合架构）构建功能、构造化简器、管理状态、处理效果、导航或测试 TCA 功能时使用。涵盖 @Reducer、Store、Effect、TestStore、reducer 组合和 TCA 模式。 来源：johnrogers/claude-swift-engineering。
