AppState is a Swift 6 library designed to simplify the management of application state in a thread-safe, type-safe, and SwiftUI-friendly way. It provides a set of tools to centralize and synchronize state across your application, as well as inject dependencies into various parts of your app.

Non-Apple Platform Support: Linux & Windows
🍎 Features marked with this symbol are specific to Apple platforms, as they rely on Apple technologies such as iCloud and the Keychain.
AppState includes several powerful features to help manage state and dependencies:
- State: Centralized state management that allows you to encapsulate and broadcast changes across the app.
- StoredState: Persistent state using
UserDefaults, ideal for saving small amounts of data between app launches. - FileState: Persistent state stored using
FileManager, useful for storing larger amounts of data securely on disk. - 🍎 SyncState: Synchronize state across multiple devices using iCloud, ensuring consistency in user preferences and settings.
- 🍎 SecureState: Store sensitive data securely using the Keychain, protecting user information such as tokens or passwords.
- Dependency Management: Inject dependencies like network services or database clients across your app for better modularity and testing.
- Slicing: Access specific parts of a state or dependency for granular control without needing to manage the entire application state.
To integrate AppState into your Swift project, you’ll need to use the Swift Package Manager. Follow the Installation Guide for detailed instructions on setting up AppState.
After installation, refer to the Usage Overview for a quick introduction on how to manage state and inject dependencies into your project.
