How do I display paginated lists in UIKit with Swift?

Displaying paginated lists in UIKit with Swift involves creating a user interface that allows users to navigate through a collection of data in manageable segments, rather than loading all items at once. This can improve performance and enhance user experience, especially with large datasets.

Example of Paginated Lists in UIKit

Below is an example of a simple implementation of pagination using a UITableView in UIKit:

import UIKit class PaginatedViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { var items: [String] = [] var currentPage: Int = 0 let itemsPerPage: Int = 20 let totalItems: Int = 100 // Assume there are 100 items in total let tableView = UITableView() override func viewDidLoad() { super.viewDidLoad() setupTableView() loadMoreItems() } func setupTableView() { tableView.delegate = self tableView.dataSource = self tableView.frame = view.bounds view.addSubview(tableView) } func loadMoreItems() { let start = currentPage * itemsPerPage let end = min(start + itemsPerPage, totalItems) for index in start.. Int { return items.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = UITableViewCell() cell.textLabel?.text = items[indexPath.row] // Load more items when the user scrolls to the bottom if indexPath.row == items.count - 1 && items.count < totalItems { loadMoreItems() } return cell } }
