Link the UITableViewCell label to next ViewController programmatically

Question

I have created 2 TableViewControllers in one ViewController programmatically as :

// contents for labels in cells for tableviewcontrollers

let contents1 : [String] = ["One:","Two:","Three:","Four:","Five:"]

let contents2 : [String] = ["Six:","Seven:","Eight:","Nine:","Ten:"]

override func viewDidLoad() {
    super.viewDidLoad()

    table1.delegate = self
    table1.dataSource = self

    table2.delegate = self
    table2.dataSource = self   
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    if(tableView.tag == 1)
    {
        return contents1.count
    }
    else if (tableView.tag == 2)
    {
        return contents2.count
}
    return 0
}

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

  let cell = tableView.dequeueReusableCell(withIdentifier: "cell",  for: indexPath as IndexPath )

    if (tableView.tag == 1)
    {
        cell.textLabel?.text = contents1[indexPath.row]
    }
    else if (tableView.tag == 2)
    {
        cell.textLabel?.text = contents2[indexPath.row]

    }
return cell
}

My question is that , how can I programmatically link "Four:" label of first TableViewController "table1" when selected to show up next new ViewController without using Segue?

if you do not want to use segue then you can use NSUserDefaults and Create Delegate method — Mayank Patel, Dec 19 '16 at 10:07
Mayank Patel @ Sir, I am beginner at Swift. Can you please elaborate the solution since I have given whole codes? — Angel Kajol, Dec 19 '16 at 10:17
Mayank Patel @ Not data, just show up next ViewController after pressing "Four:" from table1 TableViewController programmatically. — Angel Kajol, Dec 19 '16 at 10:28

Mayank Patel @ Sir, I didn't ask about the content in this link, I need to show up New ViewController while pressing "Four:" of table1 ...,,and I need to show up next new different ViewControllers while pressing "One:", "Two:", Three:". By the technique of link , it shows up same ViewControllers while pressing "One:", "Two:", Three:"Four:"..... — Angel Kajol, Dec 19 '16 at 10:37

You can UITableView's deSelectRowAt delegate method to identify the cell selection after that you can proceed to next view

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

    if cell?.textLabel?.text == "Four" { // you can use you indexPath to compare as well
        let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController
        self.navigationController.pushViewController(secondViewController, animated: true)
    }
}

Mayank Patel @ Thanx Sir, It worked for self.present(secondViewController, animated: true, completion: nil) but it didnot work for self.navigationController?.pushViewController(secondViewController,, animated: true) . It didnot push up to SecondViewController but i wanted to push with navigation controller as i need default Back button.Can you plzz help here ?? – Angel Kajol Dec 19 '16 at 11:12
You have to embed your current view controllor with navigation controllor after that you were able to push in secondviewcontrollor – Mayank Patel Dec 19 '16 at 11:14
You don't need to check the cell against nill, if you do optional unwrapping – Lefteris Dec 19 '16 at 11:17

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
    cell.textLabel?.text = pets[indexPath.row]
    // Configure the cell...

    return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    myIndex = indexPath.row
    performSegue(withIdentifier: "segue", sender: self)
