In SwiftUI, both @StateObject and @ObservedObject are used to provide a data-driven connection between an instance of a class conforming to the ObservableObject protocol and the view. The key difference lies in ownership and lifecycle.
@StateObject is used when the view owns the object and is responsible for its creation and lifecycle, ensuring that a new object isn’t created every time the view redraws.
On the other hand, @ObservedObject is used when the object is passed into the view, usually from a parent view, and the view does not own the object or control its lifecycle, meaning it could potentially be recreated if the parent view is redrawn.
