I am trying to create a view in SwiftUI where by clicking on a button, a sheet is presented. A simplified version of the code looks like this:

struct ExampleView: View {
    @State private var selectedIndex: Int = -1
    @State private var showSheet: Bool = false

    var body: some View {
        Text("Tap me!")
            .onTapGesture {
                selectedIndex = 2
                showSheet = true
            }.sheet(isPresented:$showSheet){
                VStack {
                    Text("Selected Index: (selectedIndex)")
                }
                .onAppear {
                    print("Sheet appeared: selectedIndex = (selectedIndex)")
                }
            }
    }
}

When I tap on the button, a view is presented with SelectedIndex: -1; however, in the print statement, the correct value appears(Sheet appeared: selectedIndex = 2).

What I would like is for the correct value (2) to be passed when creating the view being presented — how can I achieve that?
