libc++abi: terminating due to uncaught exception of type NSException

Assertion failure in -[UITableView _dequeueReusableCellWithIdentifier:forIndexPath:usingPresentationValues:], UITableView.m:10099

결론적으로는 identifier 가 잘못되었다는 뜻! 

 override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath)

        cell.textLabel?.text = items[(indexPath as NSIndexPath).row]
        //셀의 text lable 앞에 선언한 items를 대입
        cell.imageView?.image = UIImage(named: itemsImageFile[(indexPath as NSIndexPath).row])

        return cell
    }

여기서 주석처리로 기본 제공한 함수를 사용했는데, 그러다보니 withIdentifier 이름이 통일되지 않아 생긴 오류다. 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath)

        cell.textLabel?.text = items[(indexPath as NSIndexPath).row]
        //셀의 text lable 앞에 선언한 items를 대입
        cell.imageView?.image = UIImage(named: itemsImageFile[(indexPath as NSIndexPath).row])

        return cell
    }

 

이렇게 변경해주면 해결.
