How to convert number in UITextField and pass it to UILabel in UITableViewCell?

First, I want to build my app like this money converter.

Cell for Row 0 will have a UITextLabel as a subview of UITableViewCell, which gets a number from users.

Cell for Row 2 will have a UILabel as a subview of UITableViewCell, which will shows the calculated number.

Cell for Row 3 will have a UILabel as a subview of UITableViewCell, which will shows the calculated number. But this number would be different from the number at Row 2.

So I made 3 classes, for 'UITextField', 'UILabel', 'UITableViewController'

Here is the 'UITableViewController' class code.

class TableViewController: UITableViewController, UITextFieldDelegate {

    let fruitsComponents: [String] = ["Apple", "Banana", "Grape", "Pear"]

    let cellReuseidentifier = "cell"
    let anotherCellReuseidentifier = "anotherCell"

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.register(FruitTableViewCell.self, forCellReuseIdentifier: cellReuseidentifier)
        tableView.register(AnotherFruitTableViewCell.self, forCellReuseIdentifier: anotherCellReuseidentifier)  
    }

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

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

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath.row == 0 {
            let cell = tableView.dequeueReusableCell(withIdentifier: cellReuseidentifier, for: indexPath) as! FruitTableViewCell
            cell.textLabel?.text = fruitsComponents[indexPath.row]
            return cell
        } else {
            let cell = tableView.dequeueReusableCell(withIdentifier: anotherCellReuseidentifier, for: indexPath) as! AnotherFruitTableViewCell
            cell.textLabel?.text = fruitsComponents[indexPath.row]
            return cell
        }
    }
}

I can get a number from UITextField and calculate it in UITextLabel subclass file.

Or, I can do this in cellForRow syntex in UITableViewController class by making UITextLabel instance directly.

But the problem is, I cannot pass the calculated data to UILabel. Because, TableViewCell was made by 'dequeue' method.

1. I cannot pass the calculated data because the cells which contains UILabel subview were not made.
2. Even if the cells are made, I cannot pass the data in 'cell' to 'cell', because both 'cell' and 'cell' was made by 'dequeue' method using same 'let cell'.
3. Of course, I cannot differentiate the cell at Row2 and the cell at Row 3.

Because of this, now, I cannot make a function that converts UILabel layout after receiving the data from UITextField.
