Steps to reproduce

• Write an app which lets the user pick a folder by using UIDocumentPickerViewController
• Connect the iOS Nextcloud app to a Nextcloud instance and make sure there is at least one folder in it.
• Run your test app and pick a folder on the Nextcloud (file provider)
• check if the picked item is a directory (by using FileManager.default.fileExists(atPath: pickedURL.path(percentEncoded: false), isDirectory: &isDirectory))

Expected behaviour

isDirectory.boolValue must be true

Actual behaviour

isDirectory.boolValue is false and it looks like it is a file containing data.
The content of the file is a string: "This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client."

po String(data: try! Data(contentsOf: pickedURL), encoding: .utf8)
▿ Optional

• some : "This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client."

Reasoning or why should it be changed/implemented?

This looks like a bug
