SwiftUI forms: Stepper
New Course Coming Soon:
Get Really Good at Git
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.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
