swift-actor-persistence

Thread-safe data persistence in Swift is achieved using an actor-based repository pattern that serializes access to shared state, combining an in-memory cache with file-backed storage to eliminate data races by design.

Implement a local repository for Codable and Identifiable models by creating an actor-backed class that exposes save, delete, find, and loadAll APIs, using await to interact with the in-memory cache and durable file persistence.

Yes, Swift actors can be used for offline-first local storage across general domain models, provided the models conform to Codable and Identifiable, ensuring consistent reads and reliable atomic writes to disk.

The best way to serialize concurrent access to local storage in Swift 5.5+ is using actors, which provide serialized access to an in-memory cache combined with atomic file persistence, ensuring safe concurrent operations.

Yes, the actor-based persistence pattern supports synchronous initialization to simplify app startup loading while maintaining safety and performance, loading cached data immediately before allowing subsequent concurrent read operations.
