swift-actor-persistence

Thread-safe Swift persistence is achieved by using an actor-based repository that serializes access to an in-memory cache and file-backed storage. This prevents data races when multiple components access shared state concurrently.

Persisting Codable objects locally is best handled by a generic repository pattern that combines an in-memory cache with durable file storage. It exposes async methods to save, delete, find, and loadAll data while ensuring crash resilience through atomic file writes.

Yes, you can use Swift actors for offline data caching. The repository loads data synchronously during initialization and maintains an in-memory cache backed by file storage, providing low-latency access for offline scenarios.

Yes, actor isolation prevents data races with local storage by guaranteeing serialized access to shared state. The repository's async API enforces this isolation, simplifying concurrency management across multiple components accessing the same data.

Atomic file writes for Swift local storage are implemented within the repository's save mechanism to ensure crash resilience. This prevents data corruption by writing to temporary files before replacing the original file upon successful completion.
