SceneKit
Apple's high-level 3D rendering framework for building scenes and visualizations on iOS using Swift 6.3. Provides a node-based scene graph, built-in geometry primitives, physically based materials, lighting, animation, and physics.
Deprecation notice (WWDC 2025): SceneKit is officially deprecated across all Apple platforms and is now in maintenance mode (critical bug fixes only). Existing apps continue to work. For new projects or major updates, Apple recommends RealityKit. See WWDC 2025 session 288 for migration guidance.
