SwiftUI—如何将Picker转换为分段拾取器

struct ContentView : View {
    private var animals = ["🐶 Dog", "🐯 Tiger", "🐷 Pig"] //picker列表的数据源
    var colors = [Color.yellow, Color.orange, Color.red, Color.purple]
    @State private var selectedAnimal = 0
    var body: some View {
        VStack {
            Picker(selection: $selectedAnimal, label: Text("animals")) {
               ForEach(0 ..< animals.count) {
                Text(self.animals[$0]).tag($0)
               }
            }.pickerStyle(SegmentedPickerStyle()) //设置拾取器的样式为分段拾取器样式
            Text("Your choice: \(animals[selectedAnimal])")
        }
    }
}
