My app connects to a web service to display JSON data in a table view. Right now, its memory usage is terrible and needs improvement; while performing a memory leak check on instrument, it shows issues related to "WKWebsiteDataStore." What does this mean, and how do I resolve it? The code below shows a web view from a selected table view cell.

Code Block import UIKit
import WebKit
class ArticleViewController: UIViewController {
  
  @IBOutlet weak var articlePage: WKWebView!
  var website: ArticlesData?
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    if let url = URL(string: website?.urlWebsite ?? "" ) {
      let request = URLRequest(url: url)
      articlePage.load(request)
      // Do any additional setup after loading the view.
    }
  }
  
}

You want to use Instruments app (frequently launched from Xcode, but doesn't have to be) to capture memory use in your app. I think you probably want to start with the "Leaks" tool in Instruments.
