Swift : UIDocumentPickerViewController

I have this function

func showFilePicker() { let allowedExtensions = ["custom"]
        let documentPicker = UIDocumentPickerViewController(documentTypes: allowedExtensions, in: .import)
        documentPicker.delegate = self
        documentPicker.allowsMultipleSelection = false
        documentPicker.directoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first
        present(documentPicker, animated: true, completion: nil)

I have these keys in the app pList


The object is to display a list of files that exist ONLY in the /DOCUMENT directory belonging to the app (this is iOS), and provide no access to any other files on the device.

For testing I have manually inserted a file into the /DOCUMENT directory on the simulator

When I call this routine. It DOES show me the file, but it cannot be selected (gray)
also, navigation to other “public” directories is still active

Also it say that the first line was deprecated in ios14, but I can find no replacement syntax anywhere

I guess I could create my own custom view, but I hate to reinvent the wheel like this

I decided it was easier over-all to just make my own dialogs.
