Navigate from a ViewController to an another on didSelectRowAt programmatically - swift

Question

I have a UIViewController that contains a custom UITableView. The table has a custom UITableViewCell too.
How to navigate from the first ViewController to an another when you select/click one of the rows?
Note
I have not used StoryBoard.
Update
This my code. Each one of the classes are external file. Let me know, if you need more code.
class TestViewController: UIViewController, UITableViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .white
view.addSubview(testTableView)
}
let testTableView: TestTableView = {
let table = TestTableView()
table.register(TestTableViewCell.self, forCellReuseIdentifier: TestTableViewCell.identifier)
return table
}()
}
class TestTableView: UITableView, UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: TestTableViewCell.identifier, for: indexPath)
return cell
}
}
class TestTableViewCell: UITableViewCell {
static let identifier = "testCell"
}

Answer 1

Here is a complete answer:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let newViewController = NewViewController()
self.navigationController?.pushViewController(newViewController, animated: true)
}

Answer 2

In UIKit in order to programmatically navigate from TableCell you can do it without storyboard.
You have two ways to view next viewController
If you want to present .......
animating from bottom to top
(one thing to remember) you can not present new view without dismissing previous presented screen, otherwise app crash due to conflict of presented screen
yourTableView.deselectRow(at: indexPath, animated: true)//used for single Tap
let vC = YourViewController (nibName: "" , bundle : nil)
vC.modalPresentationStyle = .fullScreen //this line is optional for fullscreen
self.present(vC, animated: true , completion: nil)
Or if you want to View your viewController normally (2 is batter) ....
animate from right to left
yourTableView.deselectRow(at: indexPath, animated: true)
let vC = YourViewController()
self.navigationController?.pushViewController(vC, animated: true)

Answer 3

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let vc = yourCustomVCName (nibName: "yourCustomVC nibName" , bundle : nil)
self.present(vc, animated: true , completion: nil)
}
