The first thing I did after I figured out how reality composer worked is figure out how to use xCode to dynamically load in objects with collision. I was able to do so and the result is the stack of golden blocks you see on in the image above.
Reality composer is a simple, quick and dirty way to set up your 3D scenes. In order to start working with ARKit it was important for me to know the ins and outs of reality composer. In the scene above I set up a bunch of bowling pins and a bowling ball. When I load the scene in I can click on the bowling ball to fire it at the pins.
