swift-concurrency-6-2

Resolve Swift 6.2 data race compiler errors by applying SE-0466 MainActor default isolation and SE-0461 nonisolated nonsending patterns to eliminate unsafe implicit async offloading with zero runtime overhead.

Approachable concurrency in Swift 6.2 is a data-race safety model that removes implicit background offloading, utilizing MainActor default isolation to prevent unsafe concurrency present in earlier Swift versions.

Migrate an existing Swift 5.x or 6.1 app to Swift 6.2 by adopting MainActor-isolated app architecture, resolving data-race safety errors, and implementing explicit @concurrent patterns for background tasks.

Yes, you can enable safe protocol conformances for MainActor-isolated types in Swift using isolated protocol conformance patterns, avoiding unsafe workarounds while maintaining strict data-race safety.

Offload CPU-intensive background tasks in Swift 6.2 using explicit @concurrent patterns to ensure intentional background execution without accidental offloading, achieving safe data-race isolation with zero overhead.

Swift 6.1 code produces data race errors after upgrading because Swift 6.2 removes the implicit background offloading that caused unsafe concurrency, requiring explicit MainActor isolation and nonsending defaults.
