File "Expires" after 2-3 minutes swift

Question

Here is the problem: I open document with

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL){}

save url like this: "/private/var/mobile/Containers/Data/Application/E8D502A1-7F9E-4E62-8DE3-7B66D711E35D/tmp/appName/15072021.ppdf»

and after some time i want to share this file with

UIDocumentInteractionController(url: url)

but

FileManager.default.fileExists(atPath: url.path)

returns false, so i cannot do that

can anybody help?

Ask not what `UIDocumentPickerViewController` can do for you. Ask what you can do for security-scoped bookmarks. — El Tomato, Nov 27 '21 at 06:55

When importing a document using Document Picker, a copy of selected document is saved in a temporary location. If you plan to use this document later on, you must move it to a proper space in your app sandbox. Here is what Apple documentation says:

The meaning of the provided URL varies depending on the document picker’s mode:

UIDocumentPickerModeImport

The URL refers to a copy of the selected document. This document is a temporary file. It remains available only until your application terminates. To keep a permanent copy, you must move this file to a permanent location inside your sandbox.
