# digitalCrownRotation(_:) Tracks Digital Crown rotations by updating the specified binding. ``` nonisolated func digitalCrownRotation(_ binding: Binding) -> some View where V : BinaryFloatingPoint ``` ## Parameters `binding` A binding to a value that updates as the user rotates the Digital Crown. The implicit range is `(-infinity, +infinity)`. ## Discussion Use this method to receive values on a binding you provide as the user turns the Digital Crown on Apple Watch. The example below receives changes to the binding value, starting at `0.0` and incrementing or decrementing depending on the direction that the user turns the Digital Crown: ``` struct DigitalCrown: View { @State private var crownValue = 0.0 var body: some View { Text("Received Value:\(crownValue, specifier: "%.1f")") .focusable() .digitalCrownRotation($crownValue) } } ```  --- Copyright © 2026 Apple Inc.
