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

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)

If you are using delegate in your reply, please add the initializers to the code in the reply. – Diego Jiménez Jan 10 '21 at 19:01
You could also use `[UTType.item]`. – BadmintonCat Jun 30 '22 at 08:15

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

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

Results in assertion error: Passed in type public.item doesn't conform to either public.content or public.data. If you are exporting a new type, please ensure that it conforms to an appropriate parent type. @"public.data" is correct. – mkirk Apr 20 '17 at 20:04
