A curated iOS development newsletter covering several practical SwiftUI performance topics: why @Entry defaults with class types cause unnecessary view re-renders, how inline Binding(get:set:) closures add re-render overhead versus stable subscript projections, and how Equatable conformance on @Observable properties prevents spurious invalidations. Also covers SE-0526 (withDeadline for async timeouts with composable deadlines and typed CancellationError reasons), a repository pattern for keeping SwiftData behind an architectural boundary, and App Store Connect's new social media age rating questions (required from September 2026). Quick hits include iOS 27 public beta, Swift Package Index joining Apple, Swift kernel work, and AsyncImage improvements in iOS 27.
