Switch Statement on didSelectRowAt Function in Swift – Ios swift

I am using a table view and has a label in its cell. The thing I want is to change the cell label on every tap of a cell. I know that switch statement doesn’t work on indexPath. I want my cases 1 and 2 to work.

Here is my code:

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
 
  let cell = tableView.cellForRow(at: indexPath)

 switch Value {
            
        case 1:
            
            cell.cellLabel.text = "first time label changes"
        case 2:
            
            cell.cellLabel.text = "second time label changes"
            
        default:
            cell.cellLabel.text = "change the label"
        }

}

Does anyone have a solution that if I tap a cell first time case 1 should work and if I tap it again case 2 should work?

    try my code

    var count = 0
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
count += 1
let cell = tableView.cellForRow(at: indexPath)
switch count {   
    case 1:
        cell.cellLabel.text = "first time label changes"
    case 2:
        cell.cellLabel.text = "second time label changes"
        
    default:
        cell.cellLabel.text = "change the label"
    }
}

    if you need "first" when you touch it 3 times

     var count = 0
 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
   count += 1
   if count > 2 {
    count = 1
   }
   let cell = tableView.cellForRow(at: indexPath)
   switch count {   
   case 1:
     cell.cellLabel.text = "first time label changes"
   case 2:
     cell.cellLabel.text = "second time label changes"
   default:
     cell.cellLabel.text = "change the label"
  }

    var selectedRows = [Int]()
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
       
            selectedRows.append(indexPath.row)
            print(selectedRows)
            self.tableView.reloadData()
        }
    }
    
    func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
       
            if let index = selectedRows.firstIndex(of: indexPath.row) {
                selectedRows.remove(at: index)
            }
            print(selectedRows)
           self.tableView.reloadData()
            if selectedRows.isEmpty{
               
            }
        }
    }

    class TableViewCell: UITableViewCell{
 override func setSelected(_ selected: Bool, animated: Bool) {
            super.setSelected(selected, animated: animated)
            if (selected) {
                print("selected")
                
                selectImage.image = UIImage(named:"secondImage")
              } else {
                  selectImage.image = UIImage(named:"secondImage")
              }
        }
}

    if you need multiple selection write tableView.allowMultipleSelection = true
