Class outline in XCode

Question

I am looking for a XCode plugin or some configuration settings that might allow me to see the class structure in a file, by showing all defined classes, variables and functions on the right hand side of the screen much like Eclipse. An example of the same for vim can be found here. I work in both C++ and Objective-C and would like something that would work with either language. The screenshot of eclipse below demonstrates what I am talking about.

Can some one point me to such a pluign or how this can be done using the XCode settings.
