You can use NavigationLink in the List modifier to show the detail view or a new view when user taps on the list item.

For example, we could create a simple DetailView which will be shown when list item is tapped. The main ContentView has list of chocolates and when user taps on the item it shows detail view with item name and the random amount of sugar.

struct DetailView: View {
    let chocolate: String
    let amountOfSugar: Int

    var body: some View {
        VStack {
            Text("\(chocolate)")
            Text("Sugar dencity \(amountOfSugar) %")
        }
    }
}

struct ContentView: View {
    let chocolates = ["Toblerone", "Bournville", "Snickers", "Twix", "Ferrero Rocher"]
    var body: some View {
        NavigationView {
            List(chocolates, id: \.self) { chocolate in
                NavigationLink(destination:
                                DetailView(chocolate: chocolate,
                                           amountOfSugar: (1...10).randomElement() as! Int))
                {
                    Text(chocolate)
                }
            }
        }
    }
}
