SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the common and difficult-to-debug issue of data races and thread-safety bugs when building local data persistence layers in Swift apps, which can cause unexpected crashes, data corruption, and inconsistent app state.

Core Features & Use Cases

Compiler-enforced thread safety: Uses Swift's native actor model to serialize access to shared mutable state, eliminating the need for manual synchronization with locks or DispatchQueues.
In-memory cache + atomic file persistence: Combines fast O(1) in-memory lookups with durable atomic file writes to prevent data loss or corruption if the app crashes mid-write.
Use Case: Perfect for iOS/macOS offline-first apps that need to store user data, app settings, or cached content locally with guaranteed thread safety.

Quick Start

Use the swift-actor-persistence skill to build a thread-safe local repository for your Swift app's user settings that automatically saves changes to disk.

FAQPage Schema

How do I prevent data races in Swift local persistence?▼

To prevent data races in Swift local persistence, use the native actor model for compiler-enforced serialized access to shared mutable state. This approach eliminates manual synchronization with locks or DispatchQueues, preventing crashes and data corruption.

What is the best way to migrate from DispatchQueue synchronization to Swift concurrency for storage?▼

The best way to migrate from DispatchQueue synchronization to Swift concurrency for storage is adopting generic reusable repository patterns using Swift actors. This provides thread-safe local storage with in-memory caching and atomic file writes for high performance.

How does an actor-based repository handle atomic file writes in iOS?▼

An actor-based repository handles atomic file writes in iOS by combining fast O(1) in-memory lookups with durable disk persistence. This prevents data loss or corruption if the app crashes mid-write, ensuring offline-first data durability.

Can I use this Swift actor persistence pattern for offline-first app settings caching?▼

Yes, you can use this Swift actor persistence pattern for offline-first app settings caching. It is specifically designed for iOS and macOS apps to store user data, app settings, and cached content locally with guaranteed thread safety.

Do I need specific dependencies to implement thread-safe Codable model storage?▼

No specific dependencies are needed to implement thread-safe Codable model storage. The pattern uses native Swift concurrency features, requiring only that your models conform to Codable and Identifiable protocols for generic repository reuse.
