You haven't provided much information about what you are trying to do, and where it is failing, which makes it difficult for others to help.
Make sure you follow the instructions in the
README.md document, in particular the installation, and review the demo apps for examples. The
CC3HelloWorld is the simplest. If you want to use Storyboards and multiple controllers, make sure you become familiar with the
CC3DemoMultiScene demo app.
CC3UIViewController is not generally used when Cocos3D is used with Cocos2D 3.2.1. Have a look at the demo apps, and you'll notice that the
CC3_CC2_RENDER_QUEUE directive causes the
CC3UIViewController to be bypassed.
