           TextField("Please enter", text: $name)
           Button(action: {
               self.name = "Hello text"
           }) {

@State var name: String = "My Name is jack"

   var body: some View {

       VStack {
           TextField("Name:", text: $name)
           Button(action: {
               self.name = "My Name is Tim"
           }) {
               Text("Change Name")
           }
       }
