How can i stop activity view indicator after table view data loading

Question

I have UIActivityIndicatorView that i want to start animate in viewdidload before i grab data from API and load into the table view . I then want to stop animating after loading . The problem is , it continues the animation and no data is shown forever . How can i start animating and stop the animation once data is loaded into the table view : This is my code below for the view did load and response method for getting data from api.

    public enum indicatorColor {
        static let color : UIColor =  .white
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        activityIndicator.color = indicatorColor.color
        activityIndicator.startAnimating()
        tableview.isHidden = true
        tableview.separatorColor = .blue
        tableview.delegate = self
        tableview.dataSource = self
        response()
    
    }
    
    func response () {
        viewmodel.vmResponse(url: UrlPath.path.shared()) { [weak self](_) in
            DispatchQueue.main.async {
                self?.tableview.reloadData()
//                self?.activityIndicator.stopAnimating()
//                print(self?.viewmodel.articles)
            }
        
        }
    }
