iCloud Core Data Not available after running in Xcode 6 / ios 8 SDK

Question

I have an app that uses Core Data with iCloud sync. It works great in iOS 7.

I\'m having some trouble since running it in XCode 6 though, even on an iOS 7 device. Here\'

It looks like based on the screenshot of the entitlements that you have both the old (ubiquity container) and new (iCloud container) related entitlements. I found, and have seen reported, issues when both old and new entitlements are present.

For my app I kept only the old entitlements and deleted the two new ones that XCode 6 will attempt to add to fix issues that it believes are present with iCloud. The two keys I removed were:

• com.apple.developer.icloud-container-identifiers
• com.apple.developer.icloud-services

I kept only the original key (com.apple.developer.ubiquity-container-identifiers) and did not change it's value. With that the app still works in iOS 7 when built using XCode 6 GM and can access all of the data as before. In iOS 8 it will also work however it seems to require the user to have updated their account to iCloud Drive.
