iOS11 UIDocumentPickerViewController does nothing after selecting an attachement
We're currenty testing an app for iOS11 support and bumped into a problem with the new UIDocumentPickerViewController. An action opens the new UIDocumentPickerViewController, iCloud Drive is shown by default, we're tapping on the Locations button and switch to Dropbox. When selecting an attachement, the viewcontroller is dismisses but nothing is happening. When selecting an attacthement from iCloud Drive things work just fine.
While debugging we found out the delegate method is not called and following message is shown in the console output.
[UIDocumentLog] UIDocumentPickerViewController : didPickDocumentURLs called with nil or 0 URLS
Does someone else has this problem too? If yes, what's your solution. It would be nice to see this fixed before iOS11 is released.
Thanks in advance.
Kind regards
- Hi jelteliekens,
This will be fixed/implemented once iOS 11 is official released.

Apple did not broke the app picker as all other services/providers work perfectly on iOS 11 except Dropbox. Dropbox's implementation of the UIDocumentPickerViewController and
UIDocumentBrowserViewController are broken. They call documentPickerWasCancelled when the user selects a document.
The same error occured on an earlier version of Dropbox in March and that was fixed after a few releases. Looks like a regression issue to me...
Finally, just try compiling the document based app template in XCode 9. Apple's own code will not work with Dropbox.

Hi Csaba,
I may have mis-worded my question to our files team. I'll let them reply as I don't know enough about the issue.
Hi nick63,
I don't have a timeline for when our release will be approved, but I'm estimating in the next day or two.J have the same problem with mail on ios11. J cannot attach file from dropbox.
- MapleHi all,
64.3 is out in the app store. Please upgrade to it and try again. - Hi,
I just checked the Apple Store. No updates.
I am in SEA, and use the Australian Store.
Please advise. Hi Maple
Just downloaded the update (I'm based in Ireland), everything works as expected, import fixed.
Thank you!

- MapleHi nick63,
The update propagating to other app stores may take a while but shouldn't be more than a few hours. Hello,
Grateful for this thread here.
Thanks for the new update today. I had noticed Dropbox export/import stopped working with iOS 11 using UIDocumentPickerController, due to the “0 urls” issue. With 64.3 it works again.
Had to reinstall the Dropbox app though, just updating it wasn’t enough.
Best,
Sven
CC_JFHey folks! iOS engineer @ Dropbox here.
Please do update to the 64.3 version that is in the AppStore -- it has the full iOS 11 experience and should alleviate the issues you're seeing. If you have trouble seeing your files, make sure you launch the main Dropbox app once and ensure you're logged in, and you should see your Dropbox in Files. If not, try force killing and relaunching Files. We're pretty certain this is rare edge-case and will continue to make this better in future releases!
To domhof:
I'm sorry this might be a bit off-topic: Have you found a fix for this in your UIDocumentPickerExtensionViewController? I'm updating an app which has a working UIDocumentPickerExtensionViewController for iOS 10 but in iOS 11 I get the exact same error message in the client-app's console.
There is an issue in iOS 11.0 that is caused by an mismatch in the Document Picker's Info.plist. If you do not have a File Provider Extension, ensure that you only support the Import and ExportToService types, as reporting Open or Move without an associated File Provider Extension will cause your extension to behave incorrectly. It's possible that this will be fixed in a future iOS update -- but consider just removing those keys if you have them. Hope this helps!
Thanks,
Jeff
I downloaded the update this evening. While it did fix the picker issue I had to turn off my passcode for my Dropbox app. When trying to open my DP folder in Files app, there is a message to authenticate by opening the DB app to do so. Turns out the passcode has to be disabled. This is pretty ridiculous. To use Files one has to disable protection for the DB app.
Consider this: to register for this forum one must sign in the enter a 6 digit code. Seems logical but extreme given now that one has to disable protection for the DB app to use Files. Makes no sense.
