How to implement pagination in tableview cell

Screen Shot 2020-09-19 at 3.17.11 PM
My app retrieves json from the newsAPI.com . When I look at the json, it shows 2000 articles however the image show 20 values loaded into my tableview controller. How do I increase the value to implement pagination?

class LatestNewsViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

let newsData = Articles() //Model object

let urlRequest = "https://newsapi.org/v2/everything?q=coronavirus&apiKey=d32071cd286c4f6b9c689527fc195b03" //Website API
var urlSelected = ""
var articles: [Articles]? = [] // holds array of Articles data
var indexOfPageToRequest = 1
@IBOutlet weak var table_view: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()
    table_view.cellLayoutMarginsFollowReadableWidth = true
    navigationController?.navigationBar.prefersLargeTitles = true
    retriveData(n: indexOfPageToRequest)
    
    
}

func retriveData( n : Int)->Int{
    guard let aritcleUrl = URL(string: urlRequest) else { //send a request to the server
        return n
    }
    
    let request = URLRequest(url: aritcleUrl)
    let task = URLSession.shared.dataTask(with: request, completionHandler: { (data, response, error) -> Void in //collects content from website
        
        if  error != nil { // checks if content is available
            print(error ?? 0)
            return
        }
        if let data = data { // converts data to an array of Article objects
            self.articles = self.parseData(data: data)
            
            
            
        }
        
        
    })
    
    task.resume()
    return n
}


func parseData(data:Data)-> [Articles]   {
    var articles: [Articles]? = [] // holds parsed data
    
    do {
        let jsonResult = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary
        
        let jsonArticles = jsonResult?["articles"] as? [AnyObject] ?? [] // gets first head of json file and converts it to dictionary
        
        for jsonArticle in jsonArticles{ // captures data and stores it in the model object
            let article = Articles()
            article.author = jsonArticle["author"] as? String
            article.title = jsonArticle["description"] as? String
            article.publishedAt = jsonArticle["publishedAt"] as? String
            article.urlImage = jsonArticle["urlToImage"] as? String
            article.urlWebsite = jsonArticle["url"] as? String
            articles?.append(article) //put article data in the array
        }
        
        print(jsonArticles)
        
        DispatchQueue.main.async {
            
            if(articles!.count > 0)
            {
                self.table_view.reloadData()
            }
        }
        
    } catch {
        print("Nothing my guy\(error)")
    }
    
    return articles ??  [] // returns an array of articles
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 163
}



func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return articles?.count ?? 0
}


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath) as! NewsTableViewCell
    cell.authorName.text = articles?[indexPath.row].author
    cell.headLine.text = articles?[indexPath.row].title
    cell.newsImage.downloadImage(from:(self.articles?[indexPath.item].urlImage ?? "nill"))
    cell.timePublication.text = articles?[indexPath.row].publishedAt

    
    

    return cell
}

This question seems off-topic for this forum. If it's about UIKit, I'd suggest that you ask it over Apple Developer Forums instead. If it's about newsapi.org APIs, maybe you can check its documentation and/or see if there are support contacts or forums from their websites.

PS:

This address

let urlRequest = "https://newsapi.org/v2/everything?q=coronavirus&apiKey=d32071cd286c4f6b9c689527fc195b03"

returns 20 articles when I queried.
