Yes I have read that several times. It seems to be at odds with the Core Data
documentation. It is very confusing.
I have not been able to get custom structs to work properly with Core Data. So
for now I would agree with the Core Data documentation that they are somehow
not KVC compliant.

If you read all the way to the bottom of the blog, he was able to substantially
improve the results with manually-implemented scalar accessors.
Another confusing thing is that Xcode 4.2 has a new undocumented checkbox
called "Use scalar properties" in the class generation sheet. But this only
works with iOS 5 and Mac OS X 10.7.
