Best way to scroll scrollToBottom:

before call scrollToBottom method call following method

self.view.layoutIfNeeded()

extension UITableView {
    func scrollToBottom(animated:Bool)  {
        let numberOfRows = self.numberOfRows(inSection: self.numberOfSections - 1) - 1
        if numberOfRows >= 0{
            let indexPath = IndexPath(
                row: numberOfRows,
                section: self.numberOfSections - 1)
            self.scrollToRow(at: indexPath, at: .bottom, animated: animated)
        } else {
            let point = CGPoint(x: 0, y: self.contentSize.height + self.contentInset.bottom - self.frame.height)
            if point.y >= 0{
                self.setContentOffset(point, animated: animated)
            }
        }
    }
}
