ios - Application crash in IPhone 6 while reloadData

Question

I'm using collection view in side UITableViewCell, on reload

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
        guard let _cell = cell as? BrandRow else { return }

        let _flow = columnLayout
        _flow.scrollDirection = .horizontal

        _cell.collectionView.collectionViewLayout = _flow
        _cell.collectionView.delegate = self
        _cell.collectionView.tag = indexPath.section
        _cell.collectionView.dataSource = self
        _cell.collectionView.showsVerticalScrollIndicator = false
        _cell.collectionView.showsHorizontalScrollIndicator = false
        _cell.collectionView.reloadData()

    }

In iPhone 6 while cell get reused it crashes my app

_cell.collectionView.reloadData()

can anyone please let me know what's wrong with my code?
