Does it support the latest SwiftUI features?

Yes, it includes guidance for @Observable, transactional observations (SE-0475), and MainActor-isolated view models.

Can it help with legacy code migration?

Absolutely. It provides strategies to move from @preconcurrency imports and manual locks to modern structured concurrency.

What versions of Swift does this skill support?

This skill is specifically optimized for Swift 6.2 and 6.3+, including features like approachable concurrency and the latest SE proposals.

How does it handle Sendable warnings?

It follows a triage workflow to suggest the smallest safe fix, preferring immutable value types or isolation over @unchecked Sendable.

Optimizes and resolves Swift 6.3+ concurrency issues using modern actor isolation, Sendable safety, and structured async patterns.

The Swift Concurrency skill provides specialized guidance for navigating the complexities of Swift 6's strict concurrency model. It assists developers in resolving compiler diagnostics, migrating from legacy patterns to full actor isolation, and adopting 'approachable concurrency' features like SE-0466. By applying best practices for @MainActor, @concurrent functions, and Task.immediate, it ensures your iOS applications are data-race-safe, performant, and compliant with the latest Apple framework requirements.

Características Principales

01Implements approachable concurrency with default MainActor isolation (SE-0466).
