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 |

Persistenza dei dati thread-safe in Swift utilizzando attori: cache in memoria con archiviazione supportata da file, eliminando le corse dei dati in base alla progettazione. Fonte: affaan-m/everything-claude-code.
