UIWebView - PDF shadow and page numbers

Question

Does anyone know how to remove the shadow and page number for a pdf document presented in UIWebView?

I've found methods for non-Swift, but nothing for Swift.

Any help would be greatly appreciated.

UPDATE

I've found a Objective C method:

for (UIView* subView in [webView subviews])
{
    if ([subView isKindOfClass:[UIScrollView class]]) {
        for (UIView* shadowView in [subView subviews])
        {
            if ([shadowView isKindOfClass:[UIImageView class]]) {
                [shadowView setHidden:YES];
            }
        }
    }
}

Can anyone point me in the direction of a Swift method, or how to convert this to Swift. I have tried but getting nowhere I'm afraid.

Thanks in advance

Try this great answer:

func webViewDidFinishLoad(_ webView: UIWebView) {
    for shadowView in self.webView.scrollView.subviews {
        if !shadowView.isKind(of: UIImageView.self) {
            shadowView.subviews[0].layer.shadowColor = UIColor.clear.cgColor
        } else {
            shadowView.layer.shadowColor = UIColor.clear.cgColor
        }
    }
}

Don't forget to set your ViewController as the delegate of the webView
