Summary: I have a UITableView that uses auto-layout and self-sizing cells. The layout is correct most of the times. However, in a certain sequence of actions of reloading the tableView and inserting a row in it, the tableView displays the cells with the estimatedRowHeight and animates to the correct height (based on self sizing) afterward. Steps to Reproduce: - call reloadData() on a tableView - override willDisplay and insert a row in the tableView - call reloadData() again in a DispatchQueue Expected Results: - tableView has a new row inserted in it and all cells have correct heights Actual Results: - tableView has a new row inserted but cells have estimatedRowHeight just after inserting the row for a brief amount of time Configuration: Xcode Version 9.4.1 (9F2000) iOS: 11.4.1 (15G77) Sample project: https://github.com/sanketfirodiya/UITableViewTest
