Unable to input text for new task title

When I attempt to enter a new task site, the text field is selected but nothing I type echoes or is accepted
and the display on the canvas does not show a keyboard.
Also if I look at the Simulator display, the Add Task button and input text field do not appear.

Code from ContentView.swift

import SwiftUI

struct ContentView: View {

let taskStore: TaskStore
@State private var newTaskTitle = ""
private var newTaskView: some View {
    //Text("Placeholder for new task controls")
    HStack {
        TextField("Something to do", text: $newTaskTitle )
        Button("Add Task") {
            //#warning("The task title is hard coded")
            let task = Task(title: newTaskTitle)
            taskStore.add(task)
        }//.disabled(newTaskTitle.isEmpty)
    }.padding()
}
var body: some View {
    //Text("Hello, SwiftUI")
    //    .padding()
    VStack {
        newTaskView
        TaskListView(taskStore: taskStore)
    }
}

}

struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView(taskStore: .sample)
}
}
