我正在研究具有自动填充功能的搜索栏。有时在自动填充中点击单元格时会出现此错误TableView：
*** -[UITableViewRowData rectForRow:inSection:heightCanBeGuessed:] 中的断言失败，/BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3505.16/UITableViewRowData.m:1849
*** 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“在无效索引路径 ({length = 2, path = 0 - 3}) 处请求 rect”
如果我评论这条线searchBar.text = cell.textLabel!.text应用程序不会崩溃。
这是完整的功能代码：
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
let cell: UITableViewCell = tableView.cellForRow(at: indexPath)!
address = cell.textLabel!.text!
searchBar.text = cell.textLabel!.text
}
我该如何解决？
UPD：看起来它在searchBar.text = cell.textLabel!.text
我添加后崩溃了print(searchBar.text!)，它在控制台上打印了正确的值
UPD2：仅当我在搜索栏中输入内容，然后点击屏幕上的某个位置以关闭键盘，然后点击自动填充单元格之一时，应用程序才会崩溃。
