SwiftUI 17+ removes ObservableObject boilerplate with @Observable, simplifies environment injection with @Environment, and introduces task-based async patterns. The core principle: use Apple's modern APIs instead of reactive libraries.

| Observable model | @Observable | ObservableObject | | Published property | Regular property | @Published | | Own state | @State | @StateObject | | Passed model (binding) | @Bindable | @ObservedObject | | Environment injection | environment(:) | environmentObject(:) | | Environment access | @Environment(Type.self) | @EnvironmentObject |

| Async on appear | .task { } | .onAppear { Task {} } | | Value change | onChange(of:initial::) | onChange(of:perform:) |

iOS 17+ SwiftUI 패턴 구현 시 사용: @Observable/@Bindable, MVVM 아키텍처, NavigationStack, 지연 로딩, UIKit 상호 운용성, 접근성(VoiceOver/Dynamic Type), 비동기 작업(.task/.refreshable) 또는 ObservableObject/@StateObject에서 마이그레이션. 출처: johnrogers/claude-swift-engineering.
