Can this skill help migrate data from UserDefaults?

Yes, it specifically provides patterns and implementation guidance for migrating legacy UserDefaults data into a structured SwiftData PreferencesStore.

Does it support reactive UI updates?

Yes, it utilizes async observation (observeSnapshots) to create an AsyncStream, allowing your UI to reactively update whenever preferences change.

What is the PreferencesStore pattern?

It is an architectural approach for Swift applications that centralizes settings management using SwiftData for persistence, providing snapshots for thread-safety and async streams for observation.

How does it handle thread safety?

The skill implements a snapshot pattern using Sendable and Codable protocols, ensuring that preference data can be safely passed between actors and threads.

Orchestrates robust app settings persistence using SwiftData, snapshot patterns, and asynchronous observation.

关于

The Preferences Store Expert skill provides specialized architectural guidance for managing application state and user settings within Swift-based projects. It leverages the PreferencesStore pattern to implement SwiftData persistence, utilizing Sendable and Codable snapshots to ensure thread-safe data handling. This skill is ideal for developers building complex iOS or macOS applications that require a single source of truth, reactive UI updates via AsyncStream, and seamless migrations from legacy UserDefaults systems to modern database-backed storage.
