Answer 1

Swift 5:

import MobileCoreServices

    let importMenu = UIDocumentPickerViewController(documentTypes: ["public.item"], in: .import)
    importMenu.delegate = self
    importMenu.modalPresentationStyle = .fullScreen
    self.present(importMenu, animated: true, completion: nil)

Answer 2

If you want to allow any file type, you should use

UIDocumentPickerViewController* documentPicker = 
  [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.data"]
                                                         inMode:UIDocumentPickerModeImport];

See apple docs for UTI concepts

Answer 3

UIDocumentPickerViewController* documentPicker = 
  [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.item"]
                                                         inMode:UIDocumentPickerModeImport];

Answer 4

I think your best shot is to use abstract UTI types.

Using kUTTypeContent and kUTTypeItem should cover most of the file types.
