There is currently an issue with and package based documents when storing them on any service that I've tested other than iCloud Drive. You can see what I mean if you look at GarageBand: if you create a new document on Dropbox, Google Drive, Creative Cloud, or Box, and then try to open that document again, it won't work. Each of these four services seems to produce different errors, but not of them work. I have the same issue with my app which uses a FileWrapper-based UIDocument format.
My question is what I should do about it. One solution would be to change my document format so that it always produces a binary file when saving by zipping up the contents. Or should I wait until these 3rd party storage providers fix the issues and handle the support requests generated in the meantime?
Thanks,
Luke
