Declaration

nonisolated func digitalCrownRotation<V>(_ binding: Binding<V>) -> 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)
    }
}
