I was overriding the performZoom(at mousePoint: CGPoint, xValue: Double, yValue: Double) method of SCIPinchZoomModifier but it is not accessible anymore.

My Code:

import Foundation
import SciChart

public class FixedToCenterPinchZoomModifier : SCIPinchZoomModifier {

override func performZoom(at mousePoint: CGPoint, xValue: Double, yValue: Double) {
    let middle = CGPoint(x: parentSurface?.frame.midX ?? 0,
                         y: parentSurface?.frame.midY ?? 0)
    super.performZoom(at: middle, xValue: xValue, yValue: yValue)


I get the error: Method does not override any method from its superclass

Is there a way to access the protected method?
