    }else{
        print("No Image")

Answer 1

You can share contents using UIActivityViewController.

if let pdfFileUrl = URL(String("yourFileURL")) {
let vc = UIActivityViewController(activityItems: [pdfFileUrl], applicationActivities: [])
present(vc, animated: true)`enter code here`

}

Refer this for more info. Use of UIActivityViewController and UIActivityItemProvider to share PDF

Answer 2

To view and sharing purpose.

let controller = UIDocumentInteractionController(url: pdfurl)
controller.delegate = self
controller.presentPreview(animated: true)

And implement UIDocumentInteractionControllerDelegate.

extension ViewController: UIDocumentInteractionControllerDelegate {
    func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
        return self
    }

    func documentInteractionControllerDidEndPreview(_ controller: UIDocumentInteractionController) {
    }
}
