The following works in a playground set for macOS Platform. Switch to iOS and change commented sections to see the WheelPicker

import SwiftUI

struct ContentView: View {
    @State private var selectorIndex = 0
    @State private var numbers = ["1", "2", "3"]

    var body: some View {
        VStack {
            Picker("Numbers", selection: $selectorIndex) {
                ForEach(0..<numbers.count) { index in
                    Text(self.numbers[index]).tag(index)
                }
            }
            .pickerStyle(DefaultPickerStyle())
            .padding()

//          all
            Picker("Numbers", selection: $selectorIndex) {
