swift-sharing

What problem does it solve?

Swift-Sharing provides a unified approach to share mutable state across an app while ensuring changes persist and propagate to all dependents. It reduces boilerplate for coordinating state, persistence, and UI updates across modules.

Core Features & Use Cases

• Shared state across features with automatic persistence to in-memory, appStorage, and fileStorage; suitable for configuration, preferences, and cross-feature data.
• Live observation and propagation via SwiftUI and Combine so that views and models stay synchronized with the source of truth.
• Safe mutation patterns with explicit locking and structured load/save lifecycles to avoid data races in concurrent environments.

Quick Start

1. Add a Shared property to a model with a chosen storage key, e.g., Shared(.appStorage("count")) var count = 0.
2. Access and mutate the shared value via the projected value to react to changes and persist updates.
3. Run your app; changes are observed across features and persisted automatically.
