Graphical Predicate Builder in Xcode 4 with Core Data

问题

I am using Xcode 4, and I can't find a way to work with the graphical predicate builder. Is it still there? How do I use it? Where is the documentation on this?

Thanks

In XCode 4, highlight your model, then:

Choose Editor -> Add Fetch Request

Then highlight it (rename if you like). The Predicate Builder is in the right pane:
