Getting started with RealityKit

Part 0: A high level intro to the latest AR framework

Max Cobb


Before WWDC19, myself and other Augmented Reality (AR) enthusiasts were anticipating many updates to SceneKit to come along with some shiny new ARKit features; however this was not the case.

Instead Apple decided to create a whole new framework to implement AR, and dubbed this new framework RealityKit. Here we have a whole new rendering engine, made from the ground up with AR not just in mind, but as the top priority. Although there may be some features missing; with this as v1.0 I have high hopes that this will become the standard for high-performance AR. Due to the name I also believe it could be intended for use with both Augmented and Virtual Reality, but I have yet to see any evidence for this.

I started looking into RealityKit right from the start, however there’s currently limited materials out there helping people to find their feet, both if someone who is new to AR or is coming from other AR Frameworks, such as SceneKit. This collection of articles aims to get you started with understanding the new format of creating AR content programmatically with RealityKit, with new articles coming out as I use the features.


To see what was changed with RealityKit during WWDC 2020, refer to this story:
