How to scroll to the exact end of the UITableView?

Question

I have a UITableView that is populated with cells with dynamic height. I would like the table to scroll to the bottom when the view controller is pushed from vi

Answer 1

For perfect scroll to bottom solution use tableView contentOffset

func scrollToBottom()  {
        let point = CGPoint(x: 0, y: self.tableView.contentSize.height + self.tableView.contentInset.bottom - self.tableView.frame.height)
        if point.y >= 0{
            self.tableView.setContentOffset(point, animated: animate)
        }
    }

Performing scroll to bottom in main queue works bcoz it is delaying the execution and result in working since after loading of viewController and delaying through main queue tableView now knows its content size.

I rather use self.view.layoutIfNeeded() after filling my data onto tableView and then call my method scrollToBottom(). This works fine for me.
