class DataModel: ObservableObject { @Published var name = "Some Name" @Published var isEnabled = false } struct MyView: View { @StateObject private var model = DataModel() // Create the state object. var body: some View { Text(model.name) // Updates when the data model changes. MySubView() .environmentObject(model) } }
