Can I use this to migrate my project to Swift 6?

Absolutely. It provides specific strategies for migrating from @preconcurrency imports to full strict concurrency checking while maintaining backward compatibility where needed.

Does it provide guidance on UI-bound code?

Yes, it includes best practices for @MainActor isolation, particularly for @Observable view models and SwiftUI-specific concurrency patterns.

Does this skill support the latest Swift 6.3 features?

Yes, it is specifically designed for Swift 6.3+ and Xcode 26+, including support for SE-0466 (Approachable Concurrency), Mutex, and Task.immediate.

How does it help with Sendable conformance errors?

The skill follows a triage workflow to identify the smallest safe fix, preferring immutable value types or actor isolation over unsafe workarounds like @unchecked Sendable.

Resolves data-race safety errors and implements modern Swift 6.3 concurrency patterns including actors, Sendable, and structured concurrency.

This skill provides specialized expertise for navigating the complexities of Swift's modern concurrency model, specifically optimized for Swift 6.3 and Xcode 26+. It guides developers through resolving strict concurrency compiler diagnostics, adopting 'approachable concurrency' (SE-0466), and implementing robust actor-based architectures. By applying advanced patterns like nonisolated(nonsending), @concurrent attributes, and Task.immediate, the skill helps ensure iOS and macOS applications are thread-safe, performant, and compliant with the latest Apple framework standards while minimizing unnecessary boilerplate.
