In the context of SwiftUI, the choice between using Observable
and ObservableObject
depends on the specific needs of your application.
ObservableObject
is a protocol that you can use to create a class that can be observed by SwiftUI views. When properties marked with @Published
within an ObservableObject
change, SwiftUI automatically updates the views that depend on those properties. This is useful for managing state that is shared across multiple views or when you need to perform more complex state management that involves reference types.
On the other hand, Observable
is not a standard SwiftUI protocol. It might be a custom protocol or a concept from another library or context. In general, if you are working within the SwiftUI framework, ObservableObject
is the recommended approach for managing observable state in a way that integrates seamlessly with SwiftUI's declarative view updates.
For more detailed information on state management in SwiftUI, you can refer to the session SwiftUI essentials (09:43) from WWDC 2024, which discusses various tools for state management, including ObservableObject
, State
, and Binding
.
