Another useful control we can use in forms is the Stepper view, which lets us select a number and gives a - and + button to decrease or increase it.
We link it to the value of a property with a @State property wrapper, in this case counter:
struct ContentView: View {
@State private var counter = 0
var body: some View {
Form {
Stepper("The counter is \(counter)", value: $counter)
}
}
}
You can use the in parameter of Stepper to limit the range of values it can accept:
Stepper("The counter is \(counter)", value: $counter, in: 0...10)When you reach a limit, the control to increase or decrease will be gray and non-interactive.
