Get row touched UILabel for cell in TableView

Colleagues, I have a problem with getting of row when I pressed on UILabel in cell in UITableView. So, I have 

class CellOfFirstTableView: UITableViewCell

where I have

@IBOutlet weak var labelChangeSomething: UILabel!

with that cell I work in

class FirstTableViewController: UITableViewController

so I'd like to get row for pressed UILabel, but I don't know how to do it. My code for cell and action of press:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "firstCell", for: indexPath) as! CellOfFirstTableView
    let list = sortOfSomething(id: id_something)[indexPath.row]

    //tapRecognizer
    let tap = UITapGestureRecognizer(target: self, action: #selector(FirstTableViewController.tapFunction))
    cell.labelChangeSomething.isUserInteractionEnabled = true
    cell.labelChangeSomething.addGestureRecognizer(tap)

    return cell
}

and function for action:

func tapFunction(sender:UITapGestureRecognizer) {

print("Hello world")

  }

I'd like to get row of pressed UILabel (when I press in UILabel I see "Hello world", but I want see row in what UILabel is located. I can get row of pressed cell, but user may press only UILabel and don't press part's of cell where UILabel not active. Thanks for your ideas!

1)You can make use of tag property of UIView. Just add tag to the labelChangeSomething in cellForRowAtIndexPath method

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "firstCell", for: indexPath) as! CellOfFirstTableView
    let list = sortOfSomething(id: id_something)[indexPath.row]

    //tapRecognizer
    let tap = UITapGestureRecognizer(target: self, action: #selector(FirstTableViewController.tapFunction))
    cell.labelChangeSomething.isUserInteractionEnabled = true
    cell.labelChangeSomething.addGestureRecognizer(tap)
     //here added tag
    cell.labelChangeSomething.tag = indexPath.row

    return cell
}

2) update your selector method like below

func tapFunction(sender:UITapGestureRecognizer) {

if let label = sender.view as? UILabel {
   //print label tag here == indexpath.row
   print("row = \(label.tag)")
  }

}

You don't need UITapGestureRecognizer when you tap on a label in a cell you are clicking on the cell, you need to call

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)

TableViewDelegate and write this code in it.

let cell = tableView.cellForRow(at: IndexPath) as? CellOfFirstTableView
