I'm working on an iOS shoebox app, which stores records in a database, but also supports arbitrary file attachments.
The files live in the app's container, and are synced with other machines, but the app's purpose is not a general file storage mechanism and there is no explicit cloud component.
I'd like to be able to offer the user the opportunity to edit these files in-place. For example if one of them was a Numbers file, the user should be able to select it in my app, open up a share sheet, and tap Numbers to edit the document - without Numbers creating a copy of it.
At the moment, it's looking to me as though the only way to achieve this is for the shoebox app to implement a FileProviderExtension.
However, a FileProviderExtension would presumably also surface all of the attachments in the Files app, and in the file browser sheet of any other document-based app, which is not really appropriate for this use case.
Am I missing something here? Is there another way to achieve what I want?
