I would like to be able to have my app's folder available for the user to copy/save files there.
For example, if I select a photo from the gallery and choose an action to save it to Apple's Files app, I would see under "On My iPhone" a list of some apps that accept this kind of operation, such as Pages, Keynote and Numbers (this screenshot from the Simulator has none of those installed).
How would I go about making my app appear on this list?
