How to Create a UITableView Programmatically in Swift

When developing iOS applications, creating user interfaces programmatically can provide you with more control and flexibility over your layouts. This is particularly true with UITableView, a fundamental component used in many apps to display a list of scrollable items. This guide will walk you through the steps to create a UITableView entirely programmatically using Swift.

Step 1: Setting Up Your View Controller

First, ensure your view controller is prepared to handle a UITableView. This setup involves defining the table view and adding it to the view controller's view hierarchy.

Step 3: Running Your Application

With your UITableView now set up and your data source and delegate methods implemented, you can run your application. You should see a basic table with rows labeled according to their index, which you can select and interact with.

This example gives you a fundamental, yet complete understanding of creating and managing a UITableView programmatically in Swift. This approach offers a clean separation of concerns, making your code easier to manage and debug, especially for more complex table setups.
