swift-concurrency-6-2

Migrate to Swift 6.2 concurrency by enabling MainActor default inference across your app target to reduce boilerplate, then applying isolated conformances for MainActor types to ensure safe protocol adoption.

MainActor default inference is a Swift 6.2 pattern that makes app targets single-threaded by default, minimizing boilerplate while reducing data-race risks by automatically assigning MainActor isolation to types.

Use the @concurrent attribute in Swift 6.2 to explicitly offload CPU-intensive tasks when parallelism is required, preserving thread safety while optimizing performance-critical paths.

You need isolated conformances for MainActor types when adopting protocols in Swift 6.2, ensuring safe protocol adoption while maintaining the default single-threaded isolation model and reducing data races.

Yes, Swift 6.2 concurrency patterns enforce using nonisolated task isolation alongside MainActor default inference, allowing you to safely manage concurrency boundaries without adding boilerplate.

Swift 6.2 uses single-threaded default concurrency to reduce data-race risks and simplify code, requiring explicit @concurrent annotations only when parallelism is necessary for performance-critical paths.
