    func selectFiles() {

        let supportedTypes = [UTType.image, UTType.text, UTType.plainText, UTType.utf8PlainText,    UTType.utf16ExternalPlainText, UTType.utf16PlainText,    UTType.delimitedText, UTType.commaSeparatedText,    UTType.tabSeparatedText, UTType.utf8TabSeparatedText, UTType.rtf,    UTType.pdf, UTType.webArchive, UTType.image, UTType.jpeg,    UTType.tiff, UTType.gif, UTType.png, UTType.bmp, UTType.ico,    UTType.rawImage, UTType.svg, UTType.livePhoto, UTType.movie,    UTType.video, UTType.audio, UTType.quickTimeMovie, UTType.mpeg,    UTType.mpeg2Video, UTType.mpeg2TransportStream, UTType.mp3,    UTType.mpeg4Movie, UTType.mpeg4Audio, UTType.avi, UTType.aiff,    UTType.wav, UTType.midi, UTType.archive, UTType.gzip, UTType.bz2,    UTType.zip, UTType.appleArchive, UTType.spreadsheet, UTType.epub

        documentPickerController.delegate = self

        self.present(documentPickerController, animated: true, completion: nil)

Add the extension as like below and get back the pdf URL from the path inside the finishpicking function

extension YourviewController:UIDocumentPickerDelegate {

    public func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {

        guard let myURL = urls.first else {

            return

        }

        let path = myURL.absoluteString

        print("Url  : \(myURL)")

    }

          

    public func documentMenu(_ documentMenu:UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {

        documentPicker.delegate = self

        present(documentPicker, animated: true, completion: nil)

    }

    func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {

        print("view was cancelled")

        dismiss(animated: true, completion: nil)

    }

}
