使用 Form 在数组中实现 Picker 效果

struct CheckoutView: View {
    @EnvironmentObject var order3: Order
    
    static let 支付方式数组 = ["支付宝", "微信支付", "Apple Pay", "信用卡"]
    @State private var paymentType = 0
    
    var body: some View {
        Form {
            Section {
                Picker("选择您的支付方式", selection: $paymentType) {
                    ForEach (0 ..< Self.支付方式数组.count) {
                        Text(Self.支付方式数组[$0])
                    }
                }
            }
            
            Section {
                Toggle(isOn: ) {
                    Label("使用会员积分", systemImage: "wallet.pass")
                }
            }
            
        }
        .navigationTitle("支付")
        .navigationBarTitleDisplayMode(.inline)
    }
}

//预览
struct CheckoutView_Previews: PreviewProvider {
    static let order = Order()
    
    static var previews: some View {
        NavigationView{
            CheckoutView()
                .environmentObject(order)
        }
    }
}
