Implements thread-safe data persistence in Swift using actors to eliminate data races via in-memory caching and atomic file storage.
This skill provides standardized patterns for building robust, thread-safe data persistence layers in Swift 5.5+ applications. By leveraging the actor model, it enables developers to manage shared mutable state without the complexity of manual locks or DispatchQueues. It combines high-performance in-memory caching with durable, atomic file-backed storage, making it an ideal solution for offline-first mobile apps, local user data management, and any scenario requiring synchronized access to shared models.
