iOS Swift SFSafariViewController update new URL and refresh view

I'm using SFSafariViewController for load weblinks, In my case first I need to open one URL after some process/time(like 10 sec) I need to update my URL in the same tab and refresh SFSafariViewController.

if let url = URL(string: "Google.com") {
    let VC= SFSafariViewController(url: url)
    VC.delegate = self
    self.present(VC, animated: true, completion: nil)
}

There is any way to update The URL and refresh the current SFSafariViewController page?
