Answer 1

It is UIDocumentPickController. Check the apple developer documentation

let documentPicker: UIDocumentPickerViewController = UIDocumentPickerViewController(documentTypes: ["public.text"], in: UIDocumentPickerMode.import)
        documentPicker.delegate = self
        documentPicker.modalPresentationStyle = UIModalPresentationStyle.formSheet
        self.present(documentPicker, animated: true, completion: nil)

And delegate

    // MARK: - UIDocumentPickerDelegate Methods

    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {
        if controller.documentPickerMode == UIDocumentPickerMode.import {
            // This is what it should be
//            self.newNoteBody.text = String(contentsOfFile: url.path!)
        }
    }

After adding the code you should check this post too or else you will get an exception. You should go to capabilities & turn iCloud capabilities on. Add icloud containers also there

UIDocumentMenuController is the same as UIDocumentPickerViewController. But its deprecated. check the developer documentation here
