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

For iOS 12+ only, 2019 onwards...

An ongoing example of Apple's occasional bizarre incompetence, where problems go on for literally years.

It does seem to be the case that

        cell.layoutIfNeeded()
        return cell

will fix it. (You're losing some performance of course.)

Such is life with Apple.
