Swift Version of Simon Lee's answer .

// MARK: - Variables 
  var isCcBccSelected = false // To toggle Bcc.



    // MARK: UITableViewDelegate
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {

    // Hide the Bcc Text Field , until CC gets focused in didSelectRowAtIndexPath()
    if self.cellTypes[indexPath.row] == CellType.Bcc {
        if (isCcBccSelected) {
            return 44
        } else {
            return 0
        }
    }

    return 44.0
}

Then in didSelectRowAtIndexPath()

  func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    self.tableView.deselectRowAtIndexPath(indexPath, animated: true)

    // To Get the Focus of CC, so that we can expand Bcc
    if self.cellTypes[indexPath.row] == CellType.Cc {

        if let cell = tableView.cellForRowAtIndexPath(indexPath) as? RecipientTableViewCell {

            if cell.tag == 1 {
                cell.recipientTypeLabel.text = "Cc:"
                cell.recipientTextField.userInteractionEnabled = true
                cell.recipientTextField.becomeFirstResponder()

                isCcBccSelected = true

                tableView.beginUpdates()
                tableView.endUpdates()
            }
        }
    }
}
