Implements thread-safe, high-performance data persistence in Swift using the Actor model and local file storage.
This skill provides a robust pattern for building thread-safe persistence layers in Swift 5.5+ by leveraging Actors to eliminate data races at compile time. By combining in-memory caching for O(1) lookups with atomic file-based storage, it simplifies state management in concurrent applications. It is particularly useful for developers building offline-first iOS or macOS apps who want to replace legacy manual synchronization methods like DispatchQueues or locks with modern, asynchronous, and compiler-verified concurrency patterns.
