I’m attempting to obtain a PDF from an API name, and have it open robotically upon obtain within the PDF viewer (e.g. in Information). I don’t need it to be displayed in-app.

The file does obtain, and I can discover it in Information > On My iPhone > AppName, nevertheless it would not open robotically. How can I obtain that?
