Architecture deep dive: Simulating tactile 3D logistics dioramas with RealityKit and SwiftUI in an open-source iPad game

[u/yorbenvs205]

Hey everyone,

I recently open-sourced Waybill, a tactile 3D logistics diorama simulator built for iPadOS using RealityKit and SwiftUI. I wrote up a detailed technical breakdown of the architecture:

• Bridging RealityKit's Entity-Component-System (ECS) with SwiftUI state loops
• Procedural conveyor belt splines and item physics
• Maintaining a smooth 60fps on iPad while rendering dynamic lighting and shadows

Hope this helps anyone working with RealityKit on iPadOS or visionOS!
