### AI overview

This article explains the difference between SwiftUI's @StateObject and @ObservedObject property wrappers. Use @StateObject when a view creates and owns an ObservableObject, and use @ObservedObject when the object is supplied by another view. It also explains how inline object creation can reset view models, contrasts these wrappers with the ObservableObject protocol, and recommends the Observation framework for new code targeting iOS 17 and later.

### Source excerpt

@StateObject and @ObservedObject both connect an ObservableObject to a SwiftUI view. The key difference is ownership: use @StateObject when the view creates the object and @ObservedObject when the view receives it from elsewhere. Choosing the wrong wrapper can cause your model to be recreated whenever SwiftUI rebuilds a view. I made this mistake myself because both wrappers initially appeared to produce the same result. ... -> The post @StateObject vs. @ObservedObject: The differences explained appeared first on SwiftLee.
