does anyone know if and how you can sync CoreData apps with iCloud? If I understand the Apple iCould instructions right you can not sync CoreData, can you?
Given that you tagged this with Cocoa, I suggest that you watch the video for WWDC 2011 Session 315 - "What's New in Core Data on Mac OS X". For iOS, check out Session 303 - "What's New in Core Data on iOS".
These will answer all of your questions regarding Core Data and iCloud. Since this is still under NDA, that's the most I can tell you.
Here's an article with sample code: http://goddess-gate.com/dc2/index.php/post/452.
I am going to suggest you start with the new iPhoneCoreDataRecipes for iOS 5.0. You must be a registered developer.
