title: Document picker in Swift
body: <p>I'm trying to open document picker view controller on a click of a button, but there are no option shown in it. Only more option is shown as u can see in the screen shot. I want to show options of iCloud, google drive, dropbox etc. I just want to get any document, image or pdf file from the cloud storages and want to show it in my application. I have tried this code,</p>
  
  <pre><code> @available(iOS 8.0, *)
  public func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {
  
  
      let cico = url as URL
      print("The Url is : \(cico)")
  
  
      //optional, case PDF -&gt; render
      //displayPDFweb.loadRequest(NSURLRequest(url: cico) as URLRequest)
  
  
  
  
  }
  
  @available(iOS 8.0, *)
  public func documentMenu(_ documentMenu:     UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
  
      documentPicker.delegate = self
      present(documentPicker, animated: true, completion: nil)
  
  }
  
  
  
  func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
  
      print("we cancelled")
  
      dismiss(animated: true, completion: nil)
  
  
  }
  @IBAction func docsBtnTapped(_ sender: Any) {
  
      let importMenu = UIDocumentMenuViewController(documentTypes: [String(kUTTypePDF)], in: .import)
      importMenu.delegate = self
      importMenu.modalPresentationStyle = .formSheet
      self.present(importMenu, animated: true, completion: nil)
  }
  </code></pre>
