iCloud Drive as a Common Data Location, More Like Dropbox?

[jesse_the_k]

I used to keep all my fanfic on Dropbox: all my PDFs, docs, epubs, audio files and plain text notes there to access from my iPad, iPhone, and MacBook Pro.

(I'm just one person, so I don't have to worry about managing versions.)

I can't seem to do this with iCloud Drive. When I create a Project folder at iCloud Drive's root level, my iOS apps can't see the data there. The iOS apps all want their files to be inside their own app-specific folders.

Is there a way around this?
