Create UITableView Programmatically in Swift

This Swift code example will demonstrate how to create UITableView programmatically in Swift.

The code example below will cover:

  • Make ViewController conform to UITableViewDataSource, so that we can load table items into the table view
  • Make ViewController conform to UITableViewDelegate, so that we can handle events like for example when user taps on a table cell
  • Load three items from an array into the table view
  • Determine device screen size and make table view stretch full width and height
  • Set textLabel of¬†UITableViewCell
  • Implement didSelectRowAtIndexPath function, to handle events when user taps on a table view cell

UITableView programmatically. Complete Code Example in Swift.

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    
    var myTableView: UITableView  =   UITableView()
    var itemsToLoad: [String] = ["One", "Two", "Three"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        
        // Get main screen bounds
        let screenSize: CGRect = UIScreen.mainScreen().bounds
        
        let screenWidth = screenSize.width
        let screenHeight = screenSize.height
 
        myTableView.frame = CGRectMake(0, 0, screenWidth, screenHeight);
        myTableView.dataSource = self
        myTableView.delegate = self
        
        myTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "myCell")
        
        self.view.addSubview(myTableView)
        
    }
    
    
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
    {
        return itemsToLoad.count
    }
    
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath)
        
        cell.textLabel?.text = self.itemsToLoad[indexPath.row]
        
        return cell
    }
    
    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
    {
        print("User selected table row \(indexPath.row) and item \(itemsToLoad[indexPath.row])")
    }
