SwiftUI’s dedicated picker can display one or more scrollable items from which you can choose your desired item. It is recommended to use pull-down menu instead of a picker if the list is not very long. A picker typically appears at the bottom of the screen or in a popover. When you choose something in the picker, you can see an automatic checkmark next to the selected item.

To try it out let’s create a simple picker with tasty treats:

struct ContentView: View {
    @State private var selectedChocolate = "Toblerone"
    let chocolates = ["Toblerone", "Bournville", "Snickers", "Twix", "Ferrero Rocher"]

       var body: some View {
           HStack {
               Picker("Your treat", selection: $selectedChocolate) {
                   ForEach(chocolates, id: \.self) {
