SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Thread-safe data persistence for Swift apps by using the actor model to eliminate data races, combining an in-memory cache with durable file-backed storage.

Core Features & Use Cases

Actor-based repository with serialized access via actor isolation.
In-memory cache plus file persistence for fast reads and durable writes.
Offline-first capability with consistent, thread-safe local storage.

Quick Start

Create a LocalRepository<T> instance and perform asynchronous read/write operations to manage a Codable, Identifiable model with automatic persistence.

FAQPage Schema

How do I eliminate data races in Swift apps during concurrent file persistence?▼

Swift actors provide thread-safe persistence by isolating mutable state and serializing concurrent access. An actor-based repository ensures safe concurrent reads and writes to shared state while maintaining an in-memory cache backed by durable file storage.

What is the best way to build offline-first local storage in Swift 5.5+?▼

An actor-based repository pattern provides offline-first local storage by combining an in-memory cache with file-backed persistence. This ensures thread-safe, consistent data access for Swift 5.5+ apps requiring safe concurrent operations.

How do I set up a thread-safe Swift repository with Codable and Identifiable models?▼

Create a LocalRepository<T> instance where T conforms to Codable and Identifiable. Perform asynchronous read and write operations to manage the model with automatic persistence, leveraging actor isolation for thread-safe APIs.

Does actor-based local cache work with file-backed storage for offline apps?▼

Yes, actor isolation works with file-backed storage by serializing access to both the in-memory cache and file system. This combination provides thread-safe offline-first capabilities without data races in Swift applications.

When should I not use an actor model for local persistence in Swift?▼

Avoid using the actor model for local persistence when synchronous access is required or when operating outside Swift 5.5+. Actors inherently require asynchronous execution, which may add unnecessary complexity for simple, non-concurrent storage tasks.
