Using the Observations framework to observe model properties – Donny Wals

Swift 6.2 introduces the Observations framework as a new way to observe properties of @Observable models outside of SwiftUI views. This replaces the clunky withObservationTracking function with an AsyncSequence-based approach that provides cleaner syntax and 'did set' semantics. The framework allows developers to create observation sequences that emit values when model properties change, but requires careful memory management to avoid retain cycles and may miss values if consumption is slower than production.
