I want to do the following behavior: on VC (in viewDidAppear) there is a scrollView with a content size of 2 screens, I want to start scrolling to the bottom offset which can be stopped by swiping and immediately start scrolling without lifting your hand.

Scroll launch code:

let bottomOffset = CGPoint(x: 0, 
                           y: scrollView.contentSize.height - scrollView.bounds.height)
        
UIView.animate(withDuration: 7, delay: 0.0, options: [.curveLinear]) {
     self.scrollView.setContentOffset(bottomOffset, animated: false)
}

The scroll starts successfully, but it is impossible to stop it until the animation is completed.
I tried to add a view after the animation starts on top of the scroll and hide it when the animation is finished. This view can intercept the swipe and do:

self.scrollView.layer.removeAllAnimations()

But this action only stops the animation and immediately throws me onto the bottomOffset. I don’t understand how I can stop the animation in a certain place and immediately pass the swipe to the scrolling view and start scrolling it.
I’d be grateful for any ideas
