iOS 13.0 Touch begin delayed increased compare to ios 12

In my project I have tap gesture with following setup 

    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(sceneViewTapped(gesture:)))
    tapGesture.cancelsTouchesInView = true
    tapGesture.delaysTouchesBegan = true
    self.view.addGestureRecognizer(tapGesture)

And also has Touch method like override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?)

I have setup touch gesture with tapGesture.delaysTouchesBegan = true to work both gesture as well as Touch delegate methods

It is working fine till iOS12, But in iOS13 Touch delay has been increased so user must drag his finger and wait until drawing starts because touch method called delayed

Please refer below image , Sometime gesture lost , Delayed on starting of drawing.

If I remove delaysTouchesBegan it is smooth again.

Can anyone can help me to solve this ?
