Swift UITableViewAlertForLayoutOutsideViewHierarchy 错误：仅警告一次(iOS 13 GM)

在执行Segue时，我在iOS13中遇到了一个奇怪的错误，我无法理解它的含义，也找不到关于这个错误的任何文档.问题是，这似乎会导致很多延迟(几秒钟)，直到执行segue.

2019-09-11 22:45:38.861982+0100 Thrive[2324:414597] [TableView] Warning once only: UITableView was told to layout its visible cells and other contents without being in the view hierarchy (the table view or one of its superviews has not been added to a window). This may cause bugs by forcing views inside the table view to load and perform layout without accurate information (e.g. table view bounds, trait collection, layout margins, safe area insets, etc), and will also cause unnecessary performance overhead due to extra layout passes. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window. Table view: ; layer = ; contentOffset: {0, 0}; contentSize: {315, 118}; adjustedContentInset: {0, 0, 0, 0}; dataSource: >

我正在使用Hero，但我try 禁用它，并使用常规Segue，但这并没有阻止延迟.

启动segue的代码是didSelectRowAt

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if indexPath.section == 0 {
            selectedCell = realIndexFor(activeGoalAt: indexPath)
            performSegue(withIdentifier: "toGoalDetails", sender: nil)
        } else if indexPath.section == 1 {
            selectedCell = indexPath.row
            performSegue(withIdentifier: "toIdeaDetails", sender: nil)
        } else {
            selectedDecision = indexPath.row
            hero(destination: "DecisionDetails", type: .zoom)
        }
    }

然后，viewDidLoad或ViewWill中的任何代码都不会从目标VC中出现，对这一点没有任何影响(我试着对其进行注释，没有任何区别).

知道是什么原因吗？我可以分享任何其他需要的细节.

非常感谢.
