Different UITableViewCell subviews layout after tapping a cell

I've created a UITableView which has number of cells. All the cells are the same, I want to change the cell's subviews layout and the cell's height after tapping the cell. It's pretty easy to change the height of the cell itself, but I can't figure out how to change the cell's subviews layout...

Should I reload a new custom cell instead the tapped cell or just update the cell subviews frame?

This is the normal layout:

el

This is the new layout:

el

The constraints are not an issue, my question is how to add elements which were unused in a normal cell and now they needed to be reframed and enlarge (such as the main UIImageView and UILabel's)

I'd have different cells and reload them as the cells are clicked.

class TableViewController: UITableViewController {

    var largeRow: IndexPath?

    var data: [Int] = [0, 1, 2, 3, 4, 5, 6, 7]

    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

extension TableViewController {

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return data.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath == largeRow {
            return makeLargeCell(at: indexPath)
        } else {
            return makeNormalCell(at: indexPath)
        }
    }
}

extension TableViewController {
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)

        if let largeRow = largeRow {
            if largeRow == indexPath {
                self.largeRow = nil
                tableView.reloadRows(at: [indexPath], with: .fade)
            } else {
                self.largeRow = indexPath
                tableView.reloadRows(at: [largeRow, indexPath], with: .fade)
            }
        } else {
            self.largeRow = indexPath
            tableView.reloadRows(at: [indexPath], with: .fade)
        }
    }
}
