nonisolated func manipulable(using gestureState: Manipulable.GestureState) -> some View

Parameters

Discussion

Use this view modifier alongside manipulationGesture(updating:coordinateSpace:operations:inertia:isEnabled:onChanged:) when you want to allow a person to manipulate a view by interacting with a different view.

In the following example, a person can begin a manipulation gesture attached to a deck of cards which, in turn, manipulates a single card instead of the entire deck:

struct CardDeck: View {
    @State private var manipulationState = Manipulable.GestureState()

    var body: some View {
        ZStack {
            Model3D(named: "CardDeck")
                .manipulationGesture(updating: $manipulationState)
            Model3D(named: "Card")
                .manipulable(using: manipulationState)
                .opacity(manipulationState.isActive ? 1 : 0)
        }
    }
}
