My table view cells aren't showing the date of json files collected from NewsApi.com. Can someone pls help ? Link to project below
GitHub - lexypaul13/Covid-News

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"))

    if let date = articles?[indexPath.row].publishedAt{
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd"
        guard let time = dateFormatter.date(from: date) else { return cell }
        let formattedString = dateFormatter.string(from:time)
        cell.timePublication.text = formattedString
    }
    
    

    return cell
}

This looks more like a UIKit question. Someone may come by and help, but you'd have better luck asking over Apple Developer Forums since UIKit is an Apple's private framework.

On a side note:
Did you step through the code (with the debugger)? It might help you realize what's going on. Especially if the code doesn't execute something you'd expect.

I did and theres a nil value

Try to check the values too, the publishedAt string looks like this: "2020-08-22T18:55:36Z"

If you separate the logic out:

import Foundation

let string = "2020-08-22T18:55:36Z"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

if let time = dateFormatter.date(from: string) {
    
}

You'd realize that the dateFormat doesn't match the string (try it in playground). You'd actually use "yyyy-MM-dd'T'HH:mm:ss'Z'" to read from the string, the use another formatter to convert it back to string (or just change the dateFormat).

let string = "2020-08-22T18:55:36Z"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss'Z'"
if let date = dateFormatter.date(from: string) {
    dateFormatter.dateFormat = "yyyy-MM-dd"
    let newString = dateFormatter.string(from: date)
    print(newString)
}

PS

I'd suggest that you use JSONDecoder instead of JSONSerialization.
