Swift — How to implement tableView programmatically swift

In this article, I would like to show you a basic how to implement tableView by programmatically without using storyboard in Swift5.

Step:1 Let’s create your project and setup navigationView in SceneDelegate.swift file

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let windowScene = (scene as? UIWindowScene) else { return }
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UINavigationController(rootViewController: ViewController())
window.makeKeyAndVisible()
self.window = window
}

Step: 2 Add subclass “UITableViewDataSource, UITableViewDelegate” and add code below.

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
private let cellId = "cellId"
let items = ["Ant", "Bird", "Cat", "Dog"]
private let tableView: UITableView = {
  let table = UITableView()
  table.translatesAutoresizingMaskIntoConstraints = false
  return table
}()
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.title = "Animals"
tableView.dataSource = self
tableView.delegate = self
view.addSubview(tableView)
tableView.frame = view.bounds
tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellId)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath)
cell.textLabel?.text = items[indexPath.row]
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(indexPath.row)
}
}
