swift-actor-persistence

Thread-safe persistence in Swift is achieved by using an actor-based repository pattern that isolates state access. This eliminates data races by serializing read and write operations on Codable models while maintaining an in-memory cache.

Offline storage without data races is handled through actor isolation combined with atomic file writes. This approach caches Codable and Identifiable models in memory and durably persists changes to disk for offline-first apps.

Yes, actor isolation works for local storage with any Swift model conforming to Codable and Identifiable. The generic repository architecture ensures any conforming model type can be safely cached and persisted without data races.

To set up file-backed persistence, initialize a generic LocalRepository with your model type. You can then perform save and load operations to store and retrieve items through the actor-isolated, thread-safe cache and disk layer.

Yes, Swift actor-based persistence is ideal for offline-first apps requiring safe concurrent access. It combines an in-memory cache with durable, atomic file writes to disk, ensuring data integrity during concurrent operations.

Concurrent file writes cause data races because standard resources lack serialized access. Using actor isolation enforces sequential access to local storage, preventing concurrent read and write conflicts on Codable models.
