Discussion

The system calls this method after a user has lifted their finger; the row is highlighted on the initial touch, but only selected when the touch withdraws. You can use UITableViewCell.SelectionStyle.none to disable the appearance of the cell highlight on the initial touch. The system doesn’t call this method if the rows in the table aren’t selectable. See Handling Row Selection in a Table View for more information on controlling table row selection behavior.
