Fix Swift 6.2 data race compiler errors by applying actor isolation and Sendable conformance to shared state. This enforces safe concurrent access and resolves strict concurrency diagnostics.

Actor isolation in Swift concurrency is a mechanism that protects state from data races by serializing access to its data. It ensures only one task can mutate the actor's state at a time.

Resolve Sendable safety warnings in your Swift codebase by conforming custom types to the Sendable protocol and ensuring they do not capture mutable references. This guarantees safe concurrent passing across actor boundaries.

No, this Swift concurrency review focuses on minimal behavior changes. It remediates concurrency violations and compiler diagnostics by correctly applying modern patterns like actor isolation without altering logic.

You need to use Sendable conformance in Swift when passing custom types across concurrency domains, such as different actors or tasks. It guarantees the type is safe for concurrent access without data races.
