Modify gesture events(translate location) and programmatically send the modified event to another view

I want to implement a modified version of Accessibility Zoom feature. In the zoomed in view, I want to be able to interact with the buttons which is present in the view below the Zoomed In View. The following picture illustrates the issue. I have

• 1. Parent View

     • a. Child View 1

     • b. Child View 2

Gesture events are handled in ChildView1. When I get a dragGesture in ChildView2 which is the zoomed in view, I want to be able to modify the touch points and pass the event to ChildView1. I've tried various approach:

• sendAction which can be called only on UIControls. (I was looking for Swift equivalent of element.dispatchEvent(event)-available in JavaScript)

• Check if Accessibility Zoom can be invoked programmatically (Not available)

• Modify UIGestureRecognizer object to change the location(in view: UIView?) -> CGPoint in ChildView2 and invoke the selector for dragGestureHandler in ChildView1. I'm not sure of the side effects with this approach.
  
  Can you share a good approach to solve this problem or re-implement Accessibility Zoom feature?
