When should I use the @concurrent attribute?

Use @concurrent when you need to explicitly offload CPU-intensive work, such as image processing or complex calculations, to a background thread pool for parallel execution.

How does Swift 6.2 handle async functions differently?

In Swift 6.2, async functions stay on the calling actor by default. This eliminates the implicit background offloading that frequently caused data-race errors in Swift 6.1 and earlier.

What is MainActor default inference?

It is an opt-in mode in Swift 6.2 where classes and conformances are inferred as @MainActor by default, significantly reducing the amount of manual annotation required for app targets.

Can this skill help with Xcode 26 migration?

Yes, it provides specific guidance on enabling Approachable Concurrency build settings and using the migration tooling provided by the Swift compiler.

Implements modern Swift 6.2 concurrency patterns to eliminate data races while maintaining single-threaded simplicity by default.

This skill equips Claude with the specific design patterns and compiler settings introduced in Swift 6.2's 'Approachable Concurrency' model. It helps developers migrate from older Swift versions by ensuring async functions remain on the calling actor by default, properly utilizing @concurrent for explicit background tasks, and implementing isolated protocol conformances. This skill is essential for building robust MainActor-based application architectures and resolving complex data-race safety compiler errors in Xcode 26 and later.
