How to scroll to the exact end of the UITableView?

For Swift 3.0

Write a function :

func scrollToBottom(){
    DispatchQueue.main.async {
        let indexPath = IndexPath(row: self.dataArray.count-1, section: 0)
        self.tableView.scrollToRow(at: indexPath, at: .bottom, animated: true)
    }
}

and call it after you reload the tableview data

tableView.reloadData()
scrollToBottom()
