Using Vuforia with SceneKit

Hi All,

I am working on a project where I need to use SceneKit to render a 3D object that is anchored to the Vuforia image target (like the teapot in the examples), instead of the default OpenGL setup.  Can anyone explain to me how (or point me to an example / tutorial) to modify the ImageTargets example in the Sample Project (or UserDefinedTargets example, etc.) to do this?  

I found this example by googling, but it seems to be referencing an outdated version of the vuforia framework with methods that no longer exist.

Thanks!
