Patterns for building thread-safe data persistence layers using Swift actors. Combines in-memory caching with file-backed storage, leveraging the actor model to eliminate data races at compile time.

The actor model guarantees serialized access — no data races, enforced by the compiler.

| Actor (not class + lock) | Compiler-enforced thread safety, no manual synchronization | | In-memory cache + file persistence | Fast reads from cache, durable writes to disk | | Synchronous init loading | Avoids async initialization complexity | | Dictionary keyed by ID | O(1) lookups by identifier |

Swift 中使用 actor 实现线程安全的数据持久性 — 具有文件支持存储的内存缓存，通过设计消除数据竞争。 来源：affaan-m/everything-claude-code。
