ios - Importing document with UIDocumentPickerViewController warns "fileprovider plugin was invalidated" -


anytime import document via uidocumentpickerviewcontroller, see message logged console:

testapp[66587:1550086] plugin com.apple.uikit.fileprovider.default invalidated

does mean theres wrong code? or expected warning? there anyway suppress it?

@ibaction func attachfile(sender: uibutton) {     let documentpicker = uidocumentpickerviewcontroller(documenttypes: ["public.image"], inmode: .import)     documentpicker.delegate = self     self.presentviewcontroller(documentpicker, animated: true, completion: nil) }  func documentpicker(controller: uidocumentpickerviewcontroller, didpickdocumentaturl url: nsurl) { }
