What problem does it solve?

This skill helps developers add observable state tracking to Swift models using Apple's Observation framework, reducing manual change-detection boilerplate and making UI updates more reliable.

Core Features & Use Cases

• Observable models: Mark types with @Observable to enable automatic change notifications.
• Change tracking: Use withObservationTracking to identify dependencies read during a render or computation.
• SwiftUI integration: Drive UI updates by binding to observable data in SwiftUI views.
• Asynchronous streams: Utilize Observations to observe sequences of changes over time.

Quick Start

Demonstrate how to declare an @Observable class and observe changes with withObservationTracking in a simple SwiftUI example.
