This is the source code for my first attempt at creating an AR experience on iOS without using ARKit - using the built-in Ultra Wide angle camera on iphone 12/13 pro - you should be able to alt for other lenses. Heavily inspired and copied from Andrew Zheng's project, see below - however uses a CoreMotion data to rotated a SCNView overlay instead - which gives back the freedom of making 3D content easier.
For info on the camera layer - see Andrew Zheng's Medium article on a custom ARKit alternative!**
