How to scroll to Tableview Top in Pagination?

Question

I have pagination in my tableview and I scroll to bottom close to 5-6 pagination iterations down.

How do I scroll to top of the UITableview.

Solutions that I have tried with SO solutions Sol 1:

DispatchQueue.main.async {
            let indexPath = IndexPath(row: 0, section: 0)
            self.tableView.scrollToRow(at: indexPath, at: .top, animated: true)
        }

Sol 2:

DispatchQueue.main.async {
            self.tableView.setContentOffset(.zero, animated: true)
        }

Sol 3:

tableView.scroll(to: .top, animated: true)

Sol 4: https://stackoverflow.com/a/48018130

whenever I am trying, I have checked the Scrollview contentsize of the tableview

The overall scroll is tableview.scrollview contentSize = [(414.0, 30662.666544596355)] when I tap on the button to scroll to top = [(0.0, 28960.0)], gradually it is decreasing, Ideally it should to top and make [(0.0, 0.0)] right ?

How can I achieve it ?
