To manage state in SwiftUI, use @State for local view ownership and @Observable for service-owned business logic, ensuring efficient state updates. The MV pattern separates lightweight views from observable models.

The best way to architect a scalable SwiftUI app is using the Model-View (MV) pattern, emphasizing lightweight views, service-owned business logic, and clear separation of concerns. View composition breaks down complex UIs into reusable subviews.

Wire @Bindable to create bindings to observable models, and use @Environment to inject shared state down the view hierarchy. This ensures correct state handling and efficient view updates without prop drilling.

Load async data in SwiftUI by attaching the .task modifier to a view, which automatically manages the task lifecycle. It cancels the async operation automatically when the view disappears, ensuring seamless data loading.

Yes, this guidance specifically targets iOS 26+ with Swift 6.2, covering modern @Observable ownership rules and MV architecture. It provides a review checklist to ensure adherence to best practices for these versions.

Common SwiftUI state management mistakes include incorrect ownership rules for @Observable and improper wiring of @State. This guidance provides a review checklist to identify and avoid these architectural pitfalls for optimal performance.
