FAQPage Schema

How do I migrate my Swift app to Swift 6.2 concurrency safely?▼

To migrate to Swift 6.2 concurrency, adopt single-threaded code by default with explicit background offloading. This involves implementing MainActor isolation, applying isolated conformances, and using @concurrent for CPU-intensive tasks to ensure data race safety.

What is MainActor isolation in Swift 6.2?▼

MainActor isolation in Swift 6.2 establishes single-threaded default execution for your app. It ensures UI-bound code runs safely on the main thread while defining patterns for explicit background offloading when needed.

When should I use @concurrent in Swift?▼

You should use @concurrent in Swift when offloading CPU-intensive tasks to the background. It enables explicit background execution as part of the Swift 6.2 concurrency model, keeping your app responsive while avoiding data races.

Can I use isolated conformances for MainActor types in Swift?▼

Yes, isolated conformances are explicitly supported for MainActor types in Swift 6.2. This pattern allows your types to conform to protocols while maintaining strict actor isolation and safe concurrency boundaries.

What's the best way to adopt single-threaded by default execution in Swift?▼

The best way to adopt single-threaded default execution is by implementing MainActor isolation across your Swift project. You then add explicit @concurrent attributes only where background offloading for heavy CPU work is required.

Why does Swift 6.2 use single-threaded code by default?▼

Swift 6.2 uses single-threaded code by default to reduce data races through actor isolation. This model simplifies concurrency by requiring explicit background offloading for CPU-intensive tasks rather than implicit parallelism.
