Is it possible to save PDF file directly into the file without using UIActivityViewController or UIDocumentInteractionController iOS?

Question

I need to save a PDF document from URL into the device. Is it possible to save the PDF and access it from device file manager without using UIActivityViewController or UIDocumentInteractionController.

Answer 1

Add these 2 keys in your Info.plist: LSSupportsOpeningDocumentsInPlace and UIFileSharingEnabled. And set YES as the value for both.

Now you will be able use the Files app to see any file saved by your app in Documents Directory.

Answer 2

Swift 5.0 and iOS13

let documentController = UIDocumentPickerViewController(url: exportToURL, in: .exportToService)
self.present(documentController, animated: true, completion: nil)

exportToURL represent application local URL whichever file want to save into iPhone Files app.
