Replace the default `ContentView` struct with this...

ContentView.swift

struct ContentView: View {
    @State private var switchSetting = true
    @State private var stepperValue = 11
    @State private var dateValue = Date.now
    
    var body: some View {
        NavigationView {
            Form {
                Section {
                    Toggle("On or off: you choose", isOn: $switchSetting)
                    Stepper(value: $stepperValue, in: 0...11)
                        { Text("Awesomeness: \(stepperValue)")}
                    DatePicker(selection: $dateValue, label: { Text("Date") })
                }
                header: {
                    Text("First Section")
                }
                footer: {
                    Text("This section contains some useful settings.")
                }
                    
                Section {
                    Text("Hello, world!")
                    Text("Hello, world!")
                    Text("Hello, world!")
                    Text("Hello, world!")
                }
                header: {
                    Text("Second Section")
                }
            }
            .navigationTitle("SwiftUI Config Demo")
        }
    }
}
