# pageCommand(value:in:step:) Steps a value through a range in response to page up or page down commands. ``` nonisolated func pageCommand(value: Binding, in bounds: ClosedRange, step: V = 1) -> some View where V : BinaryInteger ``` ## Parameters `value` A [`Binding`](/documentation/SwiftUI/Binding) to the value to modify when the user pages up or down. `bounds` A closed range that specifies the upper and lower bounds of `value`. `step` The amount by which to increment or decrement `value`. Defaults to 1. ## Discussion Use this command to step through sections of a data model associated with a view by providing a binding to a value, a range, and step. If taking another step would cause the value to exceed the bounds, then the value remains unchanged. On tvOS, the user triggers ‘pageUp’ and ‘pageDown’ commands by pressing a dedicated button on a connected remote. For example, you can let a user page through a TV programming guide using the channel buttons: ``` struct GuideView: View { @State private var pageOffset: Int = 0 var body: some View { GuideContent(at: pageOffset) .pageCommand( value: $pageOffset, in: 0...9, step: 1) } } ``` --- Copyright © 2026 Apple Inc.
