下一个代码片段是问题的示例。

import SwiftUI

struct TestingView: View {

  @State var myText = ""
  @State var myText2 = ""

  var body: some View {
     NavigationStack {
        Form {
            Text("Row 1")
            Text("Row 2")
            TextField("Write here", text: $myText)
            TextField("Write here too", text: $myText2)
        }
        .navigationTitle("Testing Toolbar") // delete if you want no title
        .navigationBarTitleDisplayMode(.inline)
        .toolbar {
            ToolbarItemGroup(placement: .keyboard) {
                Button {
                    print("Button up pressed")
                } label: {
                    Image(systemName: "chevron.up")
                }

                Button {
                    print("Button down pressed")
                } label: {
                    Image(systemName: "chevron.down")
                }
                Spacer()
            }
        } …
