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