You can override the touchesBegan method which is triggered when a new touch is detected in a view or window. By using this method you can check a specific view is touched or not.

Try like this

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
     let touch = touches.first
     if touch?.view != self.popView {
        dismissView()
    }
}

func dismissView() {
    self.popView.isHidden = true
    view?.backgroundColor = .white
}
