In the quest to resolve the Objective-C namespace issue I'd like to experiment with prefixing a dependency's Objective-C classes based on the target being built. As an example, suppose I have in my shared library (ObjCStaticLib) a class (CWindow). I have two plugins (A and B) that will use this CWindow. To avoid A's CWindow from collidi...

When accessed in the RootViewController's cellForRowAtIndexPath:, all array objects are there and I can see it is an NSCFArray.
