A Swift library providing a strongly-typed, modern facade over UserDefaults for persistent key-value storage in Apple platform apps. It supports Codable values, SwiftUI property wrappers, change observation, and iCloud synchronization.

Use cases

• store app settings persistently across launches
• replace @AppStorage with strongly-typed defaults
• observe changes to user preference values
• store Codable types in UserDefaults
• sync app preferences across devices via iCloud
• use UserDefaults outside of SwiftUI

When to choose

• you're building a macOS, iOS, tvOS, watchOS, or visionOS app in Swift
• you want type-safe, centralized defaults with default values defined in one place
• you need SwiftUI bindings plus observation outside SwiftUI
• you want to store Codable or custom types in user defaults

When to avoid

• you need a database or large structured storage rather than key-value preferences
• you target platforms outside Apple's ecosystem
• you're not using Swift or Swift Package Manager
• you need cross-platform persistence like shared preferences on Android
