Axiom Scenekit

A practical guide for working with Apple's SceneKit when you're stuck maintaining legacy 3D code or need to prototype something quickly before migrating to RealityKit. It covers the essentials like rendering, physics, animation debugging, and loading 3D models through Model I/O. The timing matters here since SceneKit is deprecated as of iOS 26+, so this is really about keeping existing projects alive and planning your exit strategy rather than starting fresh work. If you're dealing with SwiftUI integration or have a SceneKit codebase that needs to limp along while you plan the RealityKit migration, this gives you the guardrails to do it safely.
