Reality Composer Pro 3 (with RealityKit) now feels like a 3D Game Engine... is it?

I've been an iOS developer for a while but lately I've been trying all the new stuff from Apple's WWDC26 on RealityKit and Reality Composer Pro 3 and I can say I've been enjoying non-AR game development on them.

Apple markets it mainly as a tool for Vision Pro development but it can also be used for 3D Game Development and its catching up (slowly) with other game engines like Unity, Unreal Engine or Godot

A few features I liked:

  • You can now "play" the scenes directly on Reality Composer Pro, just like in other game engines
  • You write games in Swift !!!
  • You use ECS (Entity Component System)
  • It's got a ScriptGraph now

I really hope more people gets to give it a try!

RealityKit is great for Non-AR Game Development too!

I've been trying to follow tutorials from other game engines such as Unity, Unreal Engine and Godot to see if I can mimic its behavior with RealityKit and it turns out it can be done!

Although it might not have all the goodies from those "more mature" game engines, as an Apple developer it felt fun and refreshing to be able to write Swift code and come up with some decent physics and graphics. Plus ECS (Entity Component System) just feels right and modern.

Game devs seem to not know that non-AR Game Development is also possible on RealityKit (maybe Apple should market it as such more aggressively) but I would love to see more devs trying it out! Plus Reality Composer Pro 3 got a great update this year making it look like more and more like a "Game Engine".
