SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Threadsafe data persistence for Swift apps using actors, providing a safe, serialized access path for shared state with a fast in-memory cache and durable file-backed storage.

Core Features & Use Cases

Actor-based repository with generic Codable & Identifiable models
In-memory caching synchronized via actor isolation plus atomic file writes
Suitable for offline-first apps and apps needing safe concurrent data access

Quick Start

Instantiate a LocalRepository for your Codable, Identifiable model and call save, loadAll, or delete to manage persistent data.

FAQPage Schema

How do I persist Swift Codable models safely across concurrent threads?▼

You can persist Swift Codable models safely by using an actor-based LocalRepository, which serializes access to shared state via actor isolation, maintaining an in-memory cache and performing atomic file writes for durable local storage.

What is the best way to implement thread-safe local storage in a Swift offline-first app?▼

The best way to implement thread-safe local storage in a Swift offline-first app is using a generic actor-based repository that constrains models to Codable and Identifiable, ensuring safe concurrent data access with synchronized in-memory caching and file persistence.

Does Swift actor isolation work with file persistence for local data caching?▼

Yes, Swift actor isolation works with file persistence by synchronizing an in-memory cache within the actor and executing atomic file writes, providing a safe and serialized access path for shared local data.

How do I save and load identifiable Codable items using a Swift LocalRepository?▼

To save and load identifiable Codable items, instantiate a generic LocalRepository for your model and call its save, loadAll, or delete methods to manage file-backed persistent data with synchronized in-memory caching.

Can I use this actor-based Swift persistence approach without external dependencies?▼

Yes, you can implement this actor-based Swift persistence approach without external dependencies, as it relies purely on Swift 5.5+ native concurrency features, standard Codable serialization, and local file-backed storage with atomic writes.

When should I not use actor-based persistence for local Swift storage?▼

You should not use actor-based persistence for local Swift storage if your app does not require concurrent data access or if your models do not conform to the Codable and Identifiable constraints required by the generic LocalRepository.
