swift : TableView 셀이 올바르게 선택되지 않음

데이터베이스의 셀로 채워진 tableView가 있습니다. 편집 할 셀을 선택해야합니다. 셀을 선택하면이 셀의 indexPath가 내가 만든 함수로 전송되고,이 함수는이를 가져와 indexpath내가 클릭 한 셀 아래에 새 셀을 삽입합니다 (데이터 배열에 새 요소를 추가하여 indexpath.row).

내가 가진 모든 세포가 보이면 모든 것이 잘 작동합니다. 내 tableView. 하지만 스크롤이있을 때 숨겨진 셀이 몇 개있을 때 빠르게 스크롤하여 셀을 선택하면 내 함수가 다른 곳에 새 셀을 주입 한 다음 문제가 발생하고 예상대로 작동하지 않습니다.

getCollCell내 사용자 정의 셀에서 레이블을 클릭하면 함수 가 호출됩니다.

func getCollCell(_ tableViewCellIndexPath:IndexPath,_ collectionViewCellIndexPath:IndexPath)  {
    /// this function that inject new cell
    /// this function get the indexpath of the cell that was clicked from collection of tableViewCell

heighlightCell기능 을 살펴보면 처음에는 앱이 으스러졌지만 조건을 추가 }else{ print("tableview return nil") }하자 문제를인지하기 시작했습니다

왜이 behadior? (이 이미지는 아래로) 클릭하여 셀을 추가 한 다음 다시 클릭하여 제거 할 때 발생했습니다.
