iOS11 document picker and files app - apkg files are greyed out

Hello,

We are writing an app that handles apkg files. The app's info.plist contains the correct document types and imported Type UTIs, and everything was working well until iOS11.

On iOS11 however, these files are greyed out when trying to import them from dropbox, using UIDocumentPickerViewController, or when viewing them in the Files app, in dropbox.

They appear correctly when trying to import them from iCloud Drive.

Below are the relevant fields in the info.plist file:

Is there anything we can do to make these files "importable" from dropbox? Probably not relevant, but we have the same issue with Google Drive as well. As I mentioned with iCloud Drive it works fine.

A sample apkg file can be found here: https://www.dropbox.com/s/whpjifo1uubzcgb/Test.apkg?dl=0.

Thanks in advance,

Robert

Hey @probi86, welcome to our community!

As you are writing your own app, I’m going to redirect you to our API section, where the team will be better-equipped to answer your question

Hi Robert

This is something that we believe has been fixed in the latest version of the app in the App store (currently 70.2). Could you check with that or let us know which version of the app you tested against. Also, thanks for providing us with the example file, can you tell me which configuration you're using in UIDocumentPickerViewController? That is, the UTIs and the mode?

Thanks for the reply. I have 70.2 installed, but the files are still greyed out. I am using "anki.apkg" UTI and UIDocumentPickerMode.import.

Hi Robert

In our internal testing we opened the UIDocumentPickerController with just `public.item` UTI. It seems then that we are failing at providing the correct UTI for that item. It is the case that UTIs that are unknown get vended as dynamic UTIs. And in fact we added some fallbacks to at least vend them with `public.item` as well. But it seems this is not what you want in this case, since you want only your UTI. We would need to investigate why our app can't get your new UTI directly.

Yes, we would like to import only files with this UTI. On iOS10 this was working fine, and currently it works correctly if I choose iCloud Drive in the document picker.
