Swift 6 concurrency enforces compile-time safety using actors and Sendable types to isolate state. You apply async/await to structure asynchronous flows, ensuring your iOS app scales safely without data races.

The SwiftUI @Observable macro replaces ObservableObject for granular view updates. You integrate Combine to handle reactive data flows, binding publisher outputs directly into your SwiftUI views for responsive UIs.

Typed throws in Swift 6 specify exact error types in function signatures. You define precise error enums for functions, allowing callers to handle specific error cases without broad catch blocks, yielding safer code.

Yes, you can use Swift 6 features in existing Xcode 15+ projects. You progressively adopt concurrency and SwiftUI patterns by enabling strict concurrency checking, isolating state with actors, and migrating to @Observable.

Swift 6 strict concurrency causes Sendable warnings when non-Sendable types cross actor boundaries. You resolve these by conforming custom types to Sendable, isolating state within actors, or using async/await for secure data transfer.
