Where are the relationship rules established in core data in xcode 4?

Question

This question was asked earlier in March before the release of xCode 4, but it's still relevant and no longer protected by NDA. Where are the relationship rules established in core data in xcode 4 assigned? They've disappeared from the utility window. Many thanks,

Answer 1

In the main window of Xcode 4, in the upper right corner, select the right-most 'Utilities' view. You'll find what you need in the Plural: To-Many Relationship.
