To create a UITableView with models and designated cells in Swift, you can follow these steps:

Create a new file for your model.

class Item {
    var itemName: String
    var itemDescription: String

Create a new file for your custom cell. You can create a .xib file for your cell or create a custom subclass of UITableViewCell in your project.

In viewDidLoad(), register your custom cell to the table view and set the dataSource and delegate to the view controller.


main.swift
override func viewDidLoad() {

Implement the UITableViewDataSource methods in your view controller to retrieve and display the data in your UITableView.


main.swift
extension ViewController: UITableViewDataSource {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return items.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTableViewCell", for: indexPath) as! CustomTableViewCell

        let item = items[indexPath.row]

        cell.titleLabel.text = item.itemName
        cell.descriptionLabel.text = item.itemDescription

        return cell
    }
}

Implement the UITableViewDelegate method didSelectRowAt to handle user interaction with the table view.


main.swift
extension ViewController: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        // Handle user selection of table view cell
    }
