The UIDocumentMenuViewController is deprecated since iOS11. I also found it buggy when presented from a modal view controller. Here's a direct way of using the picker:

import MobileCoreServices

private func attachDocument() {
    let types = [kUTTypePDF, kUTTypeText, kUTTypeRTF, kUTTypeSpreadsheet]
    let importMenu = UIDocumentPickerViewController(documentTypes: types as [String], in: .import)

    if #available(iOS 11.0, *) {
        importMenu.allowsMultipleSelection = true
    }

    importMenu.delegate = self
    importMenu.modalPresentationStyle = .formSheet

    present(importMenu, animated: true)
}

extension AViewController: UIDocumentPickerDelegate, UINavigationControllerDelegate {
    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        viewModel.attachDocuments(at: urls)
    }

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

As usual don't forget to add iCloud support:
