To prevent data races with async await, apply actor isolation to shared state and ensure Sendable compliance across concurrency boundaries. This approach secures background work and networking by making data transfers safe across Swift 5.9+ concurrent execution contexts.

The best way to structure a protocol oriented SwiftUI data layer is mapping app features into type-safe modules with clear contracts. Protocol oriented decomposition establishes reliable state flows using property wrappers and view composition for testable, evolvable screen architectures.

SwiftUI state management breaks during background updates due to incorrect MainActor isolation and unsafe shared state handling. Establish reliable state flows by applying proper actor isolation and Sendable compliance to prevent race conditions in view models and reusable components.

Yes, you can use actors for safe caching across iOS and server side Swift. Actor based caching isolates shared state to prevent race conditions, applying correctly to client development and server side Swift environments when paired with Sendable compliant async await operations.

You need Sendable compliance when passing data across Swift 5.9+ concurrent execution boundaries, such as background work and networking tasks. Ensuring Sendable compliance alongside actor isolation prevents race conditions and maintains value semantics in protocol oriented modules.

Design testable Swift modules using protocol oriented decomposition by mapping app features into clean layers and contracts. This type-safe architecture approach aligns with Swift API design guidelines, creating modules that are easy to test and evolve across iOS and macOS development.
