SwiftUI Picker onChange or equivalent?

Question

I want to change some other unrelated @State variable when a Picker gets changed but there is no onChanged and it\'s not possible to p

Answer 1

I think this is simpler solution:

@State private var pickerIndex = 0
var yourData = ["Item 1", "Item 2", "Item 3"]

// USE this if needed to notify parent
@Binding var notifyParentOnChangeIndex: Int    

var body: some View {

   let pi = Binding(get: {

            return self.pickerIndex

        }, set: {

            self.pickerIndex = $0

            // TODO: DO YOUR STUFF HERE
            // TODO: DO YOUR STUFF HERE
            // TODO: DO YOUR STUFF HERE

            // USE this if needed to notify parent
            self.notifyParentOnChangeIndex = $0

        })

   return VStack{

            Picker(selection: pi, label: Text("Yolo")) {
                ForEach(self.yourData.indices) {
                    Text(self.yourData[$0])
                }
            }
            .pickerStyle(WheelPickerStyle())
            .padding()

   }

}
