# init(value:in:onEditingChanged:) Creates a slider to select a value from a given range. ``` nonisolated init(value: Binding, in bounds: ClosedRange = 0...1, onEditingChanged: @escaping (Bool) -> Void = { _ in }) where V : BinaryFloatingPoint, V.Stride : BinaryFloatingPoint ``` ## Parameters `value` The selected value within `bounds`. `bounds` The range of the valid values. Defaults to `0...1`. `onEditingChanged` A callback for when editing begins and ends. ## Discussion The `value` of the created instance is equal to the position of the given value within `bounds`, mapped into `0...1`. The slider calls `onEditingChanged` when editing begins and ends. For example, on iOS, editing begins when the user starts to drag the thumb along the slider’s track. --- Copyright © 2026 Apple Inc.
