Answer 1

let openLink = NSURL(string : self.OtherContactorProfileVview.Result.CertificateList[index].CertificateFileLink)

        if #available(iOS 9.0, *) {
            let svc = SFSafariViewController(url: openLink! as URL)
            present(svc, animated: true, completion: nil)
        } else {
            let port : PDFViewer = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PDFViewer") as! PDFViewer
            port.strUrl = self.OtherContactorProfileVview.Result.CertificateList[index].CertificateFileLink
            self.navigationController?.pushViewController(port, animated: true)

        }
