SwiftUI state management relies on @State for local component state, @Binding to pass state between views, @Environment for dependency injection, and @StateObject for observable objects. This approach keeps views as pure state expressions, eliminating unnecessary ViewModels and reducing complexity.

Compose views hierarchically with proper modifier ordering, separate presentation logic from state ownership, and use @Binding to enable parent-child communication. Preview patterns validate components in isolation, ensuring testability and reusability across iOS and macOS apps.

Use SwiftUI's built-in animation modifiers alongside layout containers to create fluid transitions. Combine state changes with .task and .onChange for reactive side effects, enabling polished animations and layouts that respond to data updates and user interactions.

Yes. SwiftUI's accessibility support integrates directly into view composition. Apply accessibility modifiers alongside standard view definitions to ensure proper labeling, hints, and navigation for all users on iOS and macOS platforms.

SwiftData integrates directly into SwiftUI views through @Query and model binding. This eliminates boilerplate, enabling reactive data persistence where views automatically update when underlying models change.

SwiftUI's declarative design and built-in state management (@State, @Environment, @StateObject) make heavyweight ViewModels unnecessary. Lightweight, testable components with clear state ownership reduce cognitive overhead and potential bugs.
