What is MainActor default inference?

It is a Swift 6.2 mode that automatically treats code in application targets as MainActor-isolated, reducing the need for repetitive annotations while maintaining safety.

How do I move work to the background in Swift 6.2?

You must explicitly use the @concurrent attribute on functions to offload heavy CPU work to a concurrent thread pool, ensuring parallel execution is an intentional choice.

Can this skill help with Xcode 26 migration?

Yes, it includes specific patterns for enabling the 'Approachable Concurrency' build settings and resolving the compiler errors that arise during migration.

What is the primary change in Swift 6.2 concurrency?

Swift 6.2 introduces 'Approachable Concurrency,' where asynchronous functions stay on the caller's actor by default, preventing implicit background offloading and reducing data races.

Guides the adoption of Swift 6.2 concurrency patterns to eliminate data races through default single-threading and explicit background offloading.

This skill provides specialized implementation patterns for Swift 6.2's 'Approachable Concurrency' model, designed to make asynchronous programming safer and more intuitive. It helps developers navigate the shift where code runs on a single thread by default, provides guidance on using the @concurrent attribute for intentional parallelization, and demonstrates how to implement isolated protocol conformance for MainActor types. Whether you are migrating a legacy project or starting a new app in Xcode 26, this skill ensures your architecture remains data-race-free while maintaining high performance.
