      스크린샷 2022-08-09 오후 11.05.46스크린샷 2022-08-09 오후 11.07.00스크린샷 2022-08-09 오후 11.08.13위의 사진과 같이 장소등록 버튼을 누르면 옆의 검색창으로 이동한 뒤, 주소를 입력하면 주르륵 자동 완성 셀이 나오는 형식입니다

      그러나 어찌된 영문인지 셀은 코빼기도 안보입니다ㅠㅠㅠㅠㅠㅠ

      첨부해주신 코드만 봤을 땐 tableViewdataSource를 설정해주지 않아서 셀이 나타나지 않는 것 같네요 🤔

        extension LocationSearchViewController: UITableViewDataSource {

            

            func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

                return completerResults?.count ?? 0

            }

            

            

            func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

                guard let cell = tableView.dequeueReusableCell(withIdentifier: “Cell”) as? Cell else { return UITableViewCell() }

                        

                        if let suggestion = completerResults?[indexPath.row] {

                            cell.titleLabel.text = suggestion.title

                            cell.subtitleLabel.text = suggestion.subtitle

                            

                        }

                return cell

            }

         

        이렇게 extension으로 dataSource 설정되어있는데도 그러네요ㅠㅠㅠㅠ

          혹시 선언하신 tableView의 dataSource로 UITableViewDataSource 프로토콜을 채택한 객체(LocationSearchViewController)를 할당해주셨을까요?
