SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Thread-safe data persistence in Swift applications by combining in-memory caching with file-backed storage, eliminating data races through actor isolation.

Core Features & Use Cases

Actor-based repository pattern that guarantees serialized access to Codable & Identifiable models.
In-memory cache with durable, atomic file writes to disk for offline support.
Generic architecture that works with any model type conforming to Codable and Identifiable.
Ideal for offline-first apps needing safe concurrent access to local data.

Quick Start

Initialize a LocalRepository<YourModel>() and perform save and load operations to persist and retrieve items.

FAQPage Schema

How do I achieve thread-safe persistence in Swift for concurrent access?▼

Thread-safe persistence in Swift is achieved by using an actor-based repository pattern that isolates state access. This eliminates data races by serializing read and write operations on Codable models while maintaining an in-memory cache.

What's the best way to handle offline data storage in Swift without data races?▼

Offline storage without data races is handled through actor isolation combined with atomic file writes. This approach caches Codable and Identifiable models in memory and durably persists changes to disk for offline-first apps.

Can I use actor isolation for local storage with any Swift Codable model?▼

Yes, actor isolation works for local storage with any Swift model conforming to Codable and Identifiable. The generic repository architecture ensures any conforming model type can be safely cached and persisted without data races.

How do I set up a generic repository for file-backed persistence in Swift?▼

To set up file-backed persistence, initialize a generic LocalRepository with your model type. You can then perform save and load operations to store and retrieve items through the actor-isolated, thread-safe cache and disk layer.

Does Swift actor-based persistence work for offline-first apps requiring safe concurrent access?▼

Yes, Swift actor-based persistence is ideal for offline-first apps requiring safe concurrent access. It combines an in-memory cache with durable, atomic file writes to disk, ensuring data integrity during concurrent operations.

Why does my Swift concurrent file write cause data races?▼

Concurrent file writes cause data races because standard resources lack serialized access. Using actor isolation enforces sequential access to local storage, preventing concurrent read and write conflicts on Codable models.
