swift-actor-persistence

Thread-safe data persistence in Swift is achieved using actors to serialize access to local data. This approach guarantees compiler-enforced safety by combining an in-memory cache with file-backed storage, preventing concurrent read/write data races.

An offline-first cache requires durable file persistence combined with an in-memory cache. Using an actor-based repository pattern ensures safe shared mutable state across app components, making offline data access feasible across multiple sessions.

Yes, you can use Swift actors to store Codable models in a local file. A generic actor-based repository handles synchronous-initialization loading and atomic file writes, providing an async API to safely save and retrieve Identifiable items.

Yes, this actor-based persistence approach works for macOS apps needing safe concurrent access. It applies to both iOS and macOS platforms, utilizing the Swift actor model to serialize file storage and in-memory cache operations securely.

Using the Swift actor model for local repository file storage provides compiler-guaranteed serialized access, unlike standard queues. Actors prevent data races inherently while offering an async API for both in-memory cache and atomic file writes.
