composable-architecture

You can build scalable SwiftUI features using TCA architecture by structuring reducers, centralizing state, and coordinating effects. This approach applies @Reducer and Store patterns to create predictable state management across evolving app modules.

The best way to structure reducers for complex Swift screens is through reducer composition and modular feature wiring. TCA architecture enables combining multiple reducers to handle distinct features while maintaining centralized state and coordinated effects.

You test SwiftUI state changes and side effects deterministically using TCA's TestStore. It verifies that actions produce expected state changes and effects, ensuring comprehensive testing across multiple features with predictable outcomes.

Yes, TCA architecture handles navigation and presentation patterns within a Swift reducer architecture using unified Destination state. This coordinates navigation across multiple features while maintaining centralized state management.

TCA architecture works for managing side effects in evolving Swift app modules through Effect handling. It coordinates deterministic side effects within reducers, ensuring predictable state changes as app modules grow and require additional features.

Start scaffolding a Swift feature using TCA patterns by defining a State, an Action, and a Reducer. Wire the reducer to a SwiftUI view, then validate behavior using TestStore to verify actions and state changes.
