Assign property values together in SwiftUI view?

I'm trying to bind properties together in the view and couldn't find anything better specifically for it. This is what I'm doing:

struct ContentView: View {
    @ObservedObject var model: MyModel
    @State var selectedID: Int

    var body: some View {
        Picker("Choose", selection: $selectedID) {
              Text("Abc").tag(0)
              Text("Def").tag(1)
              Text("Ghi").tag(2)
        }
        .onChange(of: model.item?.selectedID) {
            selectedID = $0
        }
    }
}

Is there a better way to bind properties together?

If it is about unidirectional flow then the only change I see needed in provided snapshot is make similar types. Everything else is ok.

struct ContentView: View {
    @ObservedObject var model: MyModel
    @State var selectedID: Int?          // << make optional as well !!
