Scroll UICollectionView

When you show banners in UICollectionView and you want to scroll it automatically and You can also scroll UICollectionView automatically in a vertical position. First, you have to create Timer through which you can scroll UICollectionView according to your need.You can also set time period after which theUICollectionView cell scrolls

Timer.scheduledTimer(timeInterval: 4.0, target: self, selector: #selector(self.scrollAutomatically), userInfo: nil, repeats: true)

func scrollAutomatically(_ timer: Timer) {

}

Do your stuff in scrollAutomatically function

func scrollAutomatically(_ timer1: Timer) {

if let coll = bannerCollection {

for cell in coll.visibleCells {

let indexPath: IndexPath? = coll.indexPath(for: cell)

if ((indexPath?.row)! < banner.count - 1){

let indexPath1: IndexPath?

indexPath1 = IndexPath.init(row: (indexPath?.row)! + 1, section: (indexPath?.section)!)

coll.scrollToItem(at: indexPath1!, at: .right, animated: true)

}

else{

let indexPath1: IndexPath?

indexPath1 = IndexPath.init(row: 0, section: (indexPath?.section)!)

coll.scrollToItem(at: indexPath1!, at: .left, animated: true)

}

bannerCollection :- your collection view

banner.Count:- a number of cells containing a collection view
