# init(_:value:in:step:onEditingChanged:) Creates a stepper instance that increments and decrements a binding to a value, by a step size and within a closed range that you provide. ``` @export(implementation) nonisolated init(_ titleResource: LocalizedStringResource, value: Binding, in bounds: ClosedRange, step: V.Stride = 1, onEditingChanged: @escaping (Bool) -> Void = { _ in }) where V : Strideable ``` ## Parameters `titleResource` Text resource for the stepper’s localized title describing the purpose of the stepper. `value` A [`Binding`](/documentation/SwiftUI/Binding) to a value that your provide. `bounds` A closed range that describes the upper and lower bounds permitted by the stepper. `step` The amount to increment or decrement `value` each time the user clicks or taps the stepper’s increment or decrement button, respectively. Defaults to `1`. `onEditingChanged` A closure that’s called when editing begins and ends. For example, on iOS, the user may touch and hold the increment or decrement buttons on a `Stepper` which causes the execution of the `onEditingChanged` closure at the start and end of the gesture. ## Discussion Use `Stepper(_:value:in:step:onEditingChanged:)` to create a stepper that increments or decrements a value within a specific range of values by a specific step size. In the example below, a stepper increments or decrements a binding to value over a range of `1...50` by `5` at each press of the stepper’s increment or decrement buttons: ``` struct StepperView: View { @State private var value = 0 @State private var titleKey = "Stepper" let step = 5 let range = 1...50 var body: some View { VStack(spacing: 20) { Text("Current Stepper Value: \(value)") Stepper(titleKey, value: $value, in: range, step: step) } } } ```  --- Copyright © 2026 Apple Inc.
