How to amend or change the size of a PopoverPresentationController?

I have used a popoverPresentationController on iOS Swift and i have put both an image and text in the popover?

The issue i am having is that the content is too big for the popover? is it possible to set the dimensions?

Pictures are below of both the issue i am having and the trial code and error message?

  let myAlert = UIAlertController(title: "\n\n\n\n\n\n", message: "Correct answer selected, move on to next level", preferredStyle: UIAlertControllerStyle.actionSheet)

    let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.default)
    {
        //  action in self.dismiss(animated: true, completion: nil)

        action in self.performSegue(withIdentifier: "goSegue1", sender: self)

        self.musicEffect.stop()
    }
    // put image into action sheet
    let imageView = UIImageView(frame: CGRect(x: 70, y: -30, width: 140, height: 140))
    imageView.image = #imageLiteral(resourceName: "wellDone2.png")

    myAlert.addAction(okAction);
    myAlert.view.addSubview(imageView)

    // display the alert messgae

    myAlert.popoverPresentationController?.sourceView = view
    myAlert.popoverPresentationController?.sourceRect = (sender as AnyObject).frame
    myAlert.preferredContentSize = CGSize(width: 500, height: 800)

The size of the popover is not controlled by the PopoverPresentationController. The PopoverPresentationController only specifies how to present content, but the content itself, including size, is set by the view from which you have obtained the controller, in your case myAlert.

You have the right idea trying to set preferredContentSize, but you're setting it on the wrong view. You should change the line

popoverPresentationController?.preferredContentSize = /* ... */

to:

myAlert.preferredContentSize = /* ... */

This should solve the problem.
