Answer 1

try this

var index = 0
var inForwardDirection = true
var timer: Timer?

@objc func scrollToNextCell() {

    //scroll to next cell
    let items = collectionViewTable.numberOfItems(inSection: 0)
    if (items - 1) == index {
        collectionViewTable.scrollToItem(at: IndexPath(row: index, section: 0), at: UICollectionViewScrollPosition.right, animated: true)
    } else if index == 0 {
        collectionViewTable.scrollToItem(at: IndexPath(row: index, section: 0), at: UICollectionViewScrollPosition.left, animated: true)
    } else {
        collectionViewTable.scrollToItem(at: IndexPath(row: index, section: 0), at: UICollectionViewScrollPosition.centeredHorizontally, animated: true)
    }

    if inForwardDirection {
        if index == (items - 1) {
            index -= 1
            inForwardDirection = false
        } else {
            index += 1
        }
    } else {
        if index == 0 {
            index += 1
            inForwardDirection = true
        } else {
            index -= 1
        }
    }

}

/**
 call this method when collection view loaded
 */
func startTimer() {
    if timer == nil {
        timer = Timer.scheduledTimer(timeInterval: 5.0, target: self, selector: #selector(scrollToNextCell), userInfo: nil, repeats: true);
    }
}
