SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of thread-safe data persistence in Swift, providing a robust solution for avoiding data races and ensuring thread safety.

Core Features & Use Cases

  • Actor-Based Repository: Ensures serialized access and eliminates data races at compile time.
  • In-Memory Cache + File Persistence: Combines fast reads from cache with durable writes to disk.
  • Use Case: Ideal for building offline-first apps with local storage, where thread-safe access to shared mutable state is crucial.

Quick Start

Initialize a LocalRepository and use it to save, delete, and retrieve data, for example: let repository = LocalRepository<Question>().

Frequently Asked Questions about swift-actor-persistence

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I eliminate data races in Swift during concurrent file access?▼

Thread-safe data persistence in Swift is achieved by combining an in-memory cache for fast reads with file-backed storage on disk, ensuring durable writes without blocking the user interface.

Can I use the Swift actor model for offline-first app local storage?▼

Yes, the Swift actor model is ideal for offline-first apps because it provides local storage with thread-safe access to shared mutable state, combining in-memory caching with durable file persistence.

Do I need Swift 5.5 or higher to implement actor-based persistence?▼

Yes, you need Swift 5.5 or higher because actor-based persistence requires the native Swift actor model to guarantee compile-time elimination of data races during concurrent data access.

What is the best way to cache data locally in Swift without thread safety issues?▼

The best way to avoid thread safety issues in Swift local caching is using an actor-based repository, which pairs an in-memory cache for rapid retrieval with file-backed storage for durable offline writes.

When should I not use actors for data persistence in my iOS app?▼

You should avoid actor-based data persistence if your iOS app requires highly concurrent bulk background writes, because the actor model intentionally serializes access to ensure data race elimination.
