Exposing an app’s ubiquitous container to iCloud Drive in iOS 8

I was experiencing a similar problem with my application. I was able to make this work by doing the following:

1. Add the NSUbiquitousContainers setting to my Info.plist file according to documentation here https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/ExtensibilityPG/FileProvider.html. Here is the relevant code:

   <dict>
       <!-- ... other top-level Info.plist settings ... -->
       <key>NSUbiquitousContainers</key>
       <dict>
           <key>iCloud.com.example.MyApp</key>
           <dict>
               <key>NSUbiquitousContainerIsDocumentScopePublic</key>
               <true/>
               <key>NSUbiquitousContainerSupportedFolderLevels</key>
               <string>Any</string>
               <key>NSUbiquitousContainerName</key>
               <string>MyApp</string>
           </dict>
       </dict>
   </dict>
   

2. Important! I then changed the above NSUbiquitousContainerSupportedFolderLevels string value from Any to One

   <key>NSUbiquitousContainerSupportedFolderLevels</key>
   <string>One</string>
   

3. Next, and last, I had to change CFBundleVersion to a higher version. I also bumped the CFBundleShortVersionString to a new version as well.

Built and ran and after that, the folder with my applications icon appeared properly in iCloud Drive! Hope this helps!
