Change tintcolor of SFSafariViewController?

Some news from iOS 10: now we have two properties to control the overall looks of the SFSafariViewController

source: link

The only downside is, of course, it's not available for older versions.

if #available(iOS 10.0, *) {
    safariVC.preferredBarTintColor = .black
    safariVC.preferredControlTintColor = .white
} else {
    safariVC.view.tintColor = .someColor
}

It's a property of the view, safariVC.view.tintColor = UIColor.someColor()
