Apple Drop Core Data Assistant – Thanks!

Apple released XCode 4 and every XCode 3 programmer moaned ‘you’ve ruined it!’. But I said ‘stop moaning and get used to it. It’s not that different!’. Until now.
While going through the book Learn Cocoa on the Mac (which is very good, by the way), I came to a stumbling block at Chapter 7 – Core Data Basics. Basically, the book was written for XCode 3 but I’m on XCode 4. There was no problems with this until chapter 7, where I found that Apple had decided to remove a huge chunk of functionality: the Core Data Interface Assistant.
This was a brilliant time saving tool that created a user interface from a database design in just a few clicks of the mouse. It’s now gone and Apple just seem to be pretending it never even existed. There’s no reference to it in any of it’s XCode 4 documentation, not even the transition guide, which is specifically aimed at those experienced in using XCode 3.
I tried Google, of course, and found a load of other people in the same boat. The answer to these people’s questions? “you’re shafted!”
So, to move on, I had to work it out myself. If you’re interested in how I did it then read here.
But, Apple, if you’re listening, please don’t remove any more useful tools. I really don’t want to find myself writing “Where’s Interface Builder Gone?”
