@ObservedObject
Last updated
What is @ObservedObject?
@ObservedObject is a property wrapper in SwiftUI used to subscribe to an external class that conforms to the ObservableObject protocol. When the observable object publishes changes (typically through @Published properties), any views observing it will automatically update to reflect the new data. This allows you to manage and share state across different parts of your SwiftUI application, ensuring that the UI stays synchronized with the underlying data model.
