How does it handle background tasks?

It utilizes modern patterns like @concurrent and nonisolated(nonsending) to ensure intensive work is offloaded from the main actor correctly and efficiently.

Is it compatible with SwiftUI architecture?

Yes, it is designed for modern Apple frameworks, featuring deep integration with @Observable types and @MainActor-isolated view models.

Can it help fix 'Sendable' warnings?

Absolutely. It provides specific triage workflows for resolving Sendable errors and determining when to use immutable value types versus actor isolation.

Does this skill support Swift 6.2+ features?

Yes, it includes support for SE-0466 (Approachable Concurrency), default MainActor isolation, and Swift 6.2/6.3 language diagnostics.

Mobile Development

Resolves Swift concurrency errors, implements actor isolation, and migrates codebases to Swift 6 data-race safety.

This skill provides specialized guidance for modern Swift development, focusing on the strict concurrency requirements of Swift 6.2 and 6.3. It assists developers in resolving Sendable conformance errors, implementing actor isolation patterns, and utilizing advanced language features like approachable concurrency (SE-0466), Task.immediate, and nonisolated(nonsending). Whether you are migrating a legacy codebase or building new SwiftUI apps for iOS 26+, this skill ensures your code is data-race safe and follows Apple's latest architectural best practices for structured concurrency.
