var nextPage:Int = 0

@objc func clickFn(sender:UIButton){ print(nextPage) print(vcs.count)

    if(nextPage == (vcs.count-1)){
        return
    }
    nextPage += 1
    let nextItem = NSIndexPath(row: nextPage, section: 0)
    collectionView?.scrollToItem(at: nextItem as IndexPath, at: .centeredHorizontally, animated: true)
}

solution is simple. collectionView.collectionViewLayout.invalidateLayout() collectionView.scrollToItem(at: index, at: .centeredHorizontally, animated: false) This is working well.
