Allow interaction with view behind depending on UITouch.TouchType using point(inside:with:). (PKCanvasView)

Question

The problem

I am trying to intercept touches on a view using the following logic:

1. Determine whether UITouch.TouchType is .pencil
2. If not .pencil, pass touches through to view below
3. Else if .pencil, handle touch. (UIGestureRecognizer)

My attempt

After some research I found that the way to allow a touch to be handled by the view below was by using point(inside:with:) and returning false when this was required.

This was fine if i wanted to use CGPoint location to determine the Bool but in my case I need to access the UITouch itself.

I tried using the UIEvent passed into the function to access the touches associated to that event but that would only return an empty set of UITouch.

Here is my subclass used to implement this approach:

class ThroughTouchesPKCanvasView: PKCanvasView {
    override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
        print("Override point")
        if let event = event{
            print(event.allTouches) //prints: Optional(Set([]))
            return super.point(inside: point, with: event)
        } else {
            return super.point(inside: point, with: event)
        }
    }
}

So, in summary, How can I pass touches on to a view below depending on whether the user used an apple pencil for the touch?
