    You can Use this

    self.collectionView.scrollToItem(at:IndexPath(item: index, section: 0), at: .right, animated: false)

    Try performing the scroll operation after a short delay:

        dataSource.apply(snapshot, animatingDifferences: false, completion: {
        DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + .milliseconds(10)) {[weak self] in
            if let self  = self, let indexToScrollTo = self.visibleIndex {
                self.scrollToIndex(indexToScrollTo)
            }
        }
    })
