UITableView dynamic cell heights only correct after some scrolling

Question

I have a UITableView with a custom UITableViewCell defined in a storyboard using auto layout. The cell has several multiline UILabels.

Answer 1

None of the above solutions worked but the following combination of the suggestions did.

Had to add the following in viewDidLoad().

DispatchQueue.main.async {

        self.tableView.reloadData()

        self.tableView.setNeedsLayout()
        self.tableView.layoutIfNeeded()

        self.tableView.reloadData()

    }

The above combination of reloadData, setNeedsLayout and layoutIfNeeded worked but not any other. Could be specific to the cells in the project though. And yes, had to invoke reloadData twice to make it work.

Also set the following in viewDidLoad

tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = MyEstimatedHeight

In tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)

cell.setNeedsLayout()
cell.layoutIfNeeded()
