If you wish, refer to this answer

Here it's anyways (just in case if it got deleted)

Tested in Swift 5, you can use the following simple extension:

// Activity Indicator Extension
var vSpinner : [UIView] = []

extension UIViewController {
    func showSpinner(onView : UIView) {
        let spinnerView = UIView.init(frame: onView.bounds)
//        spinnerView.backgroundColor = UIColor.init(red: 0.8, green: 0.8, blue: 0.8, alpha: 0.9)
        let ai = UIActivityIndicatorView.init(style: .medium)
        ai.startAnimating()
        ai.center = spinnerView.center
        
        DispatchQueue.main.async {
            spinnerView.addSubview(ai)
            onView.addSubview(spinnerView)
        }
        
        vSpinner.append(spinnerView)
    }
    
    func removeSpinner() {
        DispatchQueue.main.async {
            vSpinner.popLast()?.removeFromSuperview()
        }
    }
}

Within your async task use these two handy boys:

showSpinner(onView: self.view) Remember to replace self.view with any kind of view you desire

self.removeSpinner() Remove the loading indicator:

Drag the Activity Indicator View to the ViewController class and add the following code after this line // webView.loadRequest(request) // or which ever line loads the url.

activityIndicatorView.startAnimating()

To stop animation use

activityIndicatorView.stopAnimating()

You can also use a stop and start button or any other Action .
