Fix data race errors in Swift 6 strict concurrency migration by applying actor isolation to shared state and conforming types to the Sendable protocol. This ensures thread-safe access across concurrent contexts and prevents invalid mutable data sharing.

The best way to use actors for thread safety in Swift is to isolate mutable state within an actor instance. This serializes access to its properties, ensuring safe concurrent execution without explicit locks.

Swift memory management with InlineArray and Span types works by providing zero-overhead, contiguous memory access. These low-level types enable performance-critical applications to optimize memory layouts without standard collection overhead.

You need to use the Sendable protocol in Swift concurrency when passing data across actor boundaries or concurrent tasks. Marking types as Sendable guarantees they can be safely shared without causing data races.

Swift 6 strict concurrency requires actors or Sendable conformances for all shared mutable state to ensure thread safety. It enforces compile-time data race prevention, demanding explicit isolation for concurrent data access.
