This implies that you’re not manipulating your “myListRoot” property in a way
compliant with Key-Value Observing.
Just manipulating the instance variable will not post KVO notifications for the
property. You need to manipulate the property (for example, by working with
the proxy NSMutableArray

I suspect what’s going on is that your unit tests are built non-GC, but the
framework you’re linking against is GC-only. You’ll need to enable GC for your
unit tests too, if you want to test a GC-only framework; Objective-C garbage
collection is on a per-process not per-binary basis.

Xcode 3.0 and 3.1 are for Mac OS X 10.5 Leopard.
For Mac OS X 10.4 Tiger, you want Xcode 2.0 through 2.5. I recommend Xcode 2.5
in the strongest possible terms; it fully supports development for Mac OS X on
both PowerPC- and Intel-based 32-bit Macs, and basic libSystem development for
64-bit Ma

What end goal do you want to accomplish with an equivalent to SetWindowProperty?
There isn't necessarily a 1:1 correspondence between API in different
