func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) { let cico = url as URL print("The Url is : \(cico)") — Ajay Sangani, Jan 29 '18 at 05:50
UIDocumentPicker will returns you the file URL, from that URL you needs to create the file or download the file from that URL your self. — Vandit Mehta, Jan 29 '18 at 05:52
How can create the file or download the file from url in iOS swift? @VanditMehta — Ajay Sangani, Jan 29 '18 at 05:54
like, if URL of image then you should write, UIImage *receipt = [UIImage imageWithContentsOfFile:url.path]; — Vandit Mehta, Jan 29 '18 at 06:08

I don't know if this comment help you or not but I think when you get file url, you need to show that url data in web view. because web view support all kind of data to show. — bittu, Jan 29 '18 at 06:53
Then I think as @VanditMehta suggest you can create image type object for image, audio type object for audio etc and send it over chat. Other than that I don't think there is any other option. — bittu, Jan 29 '18 at 07:16

You can get file easily like,

If you need to get image

    @IBAction func btn_Handler_iCloud(_ sender: Any) {
        let doc = UIDocumentMenuViewController(documentTypes: [String(kUTTypeImage)], in: .import)
        doc.delegate = self
        doc.modalPresentationStyle = .formSheet
        self.present(doc, animated: true, completion: nil)
    }

    func documentMenu(_ documentMenu: UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
        documentPicker.delegate = self
        present(documentPicker, animated: true, completion: nil)
    }

    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        let data = try! Data(contentsOf: urls[0])
        imageview_Buaty.image = UIImage.init(data: data)
    }

    func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
        dismiss(animated: true, completion: nil)
    }

Getting document URL or data from UIDocumentPickerViewController:

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) { 
    // Available from iOS 8.0 to iOS 11.0
    self.handleFileSelection(inUrl: url)// Here url is document's URL
}

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
    // Available from iOS 11.0
    self.handleFileSelection(inUrl: urls.first!)  // Here urls is array of URLs
}

private func handleFileSelection(inUrl:URL) -> Void {
    do { 
     // inUrl is the document's URL
        let data = try Data(contentsOf: inUrl) // Getting file data here
    } catch {
        dLog(message: "document loading error")
    }
}
