# digitalCrownRotation(_:from:through:sensitivity:isContinuous:isHapticFeedbackEnabled:onChange:onIdle:) Tracks Digital Crown rotations by updating the specified binding. ``` nonisolated func digitalCrownRotation(_ binding: Binding, from minValue: V, through maxValue: V, sensitivity: DigitalCrownRotationalSensitivity = .high, isContinuous: Bool = false, isHapticFeedbackEnabled: Bool = true, onChange: @escaping (DigitalCrownEvent) -> Void = { _ in }, onIdle: @escaping () -> Void = { }) -> some View where V : BinaryFloatingPoint ``` ## Parameters `binding` A binding to a value that updates when the user rotates the Digital Crown. `minValue` Lower end of the range reported. `maxValue` Upper end of the range reported. `sensitivity` How much the user needs to rotate the Digital Crown to move between two integer numbers. `isContinuous` Controls if the value reported stops at `minValue` and `maxValue`, or if it should wrap around. Default is `false`. `isHapticFeedbackEnabled` Controls the generation of haptic feedback when turning the Digital Crown. Default is `true`. `onChange` A block that is called as the Digital Crown is rotated. `onIdle` A block that is called when the Digital Crown has settled to an idle state. ## Discussion Use this method to receive continuous values on a binding you provides as the user turns the Digital Crown on Apple Watch. The example below receives changes to the binding value, starting at the `minValue` of `0.0` up to the `maxValue` of `10.0` settling in to multiples of `0.1` increasing or decreasing depending on the direction that the user turns the Digital Crown, rolling over if the user exceeds the specified boundary values: ``` struct DigitalCrown: View { @State private var crownValue = 0.0 @State private var minValue = 0.0 @State private var maxValue = 10.0 @State private var velocity = 0.0 @State private var isIdle = true var body: some View { Text("Received Value:\(crownValue, specifier: "%.2f")") .focusable() .digitalCrownRotation($crownValue, from: minValue, through: maxValue, sensitivity: .low, isContinuous: true ) { crownEvent in isIdle = false velocity = crownEvent.velocity } onIdle: { isIdle = true } } } ```  --- Copyright © 2026 Apple Inc.
