         let lastItemIndex = (self.collectionView.numberOfItems(inSection: lastSectionIndex)) - 1
           let index =  IndexPath(item: lastItemIndex, section: lastSectionIndex)
           if messages.count != 0{
               self.collectionView!.scrollToItem(at: index, at: UICollectionView.ScrollPosition.bottom, animated: false)
           }    }
