一覽

ARKit is Apple's AR framework for iOS. Detects surfaces, recognizes objects, places 3D content, handles light estimation, and powers Vision Pro spatial computing. Learning takes 4-6 months (Swift + ARKit + 3D graphics). Demand is growing: Apple pushing AR heavily; 150M+ ARKit-capable devices. Mastery earns $120k-180k.

什麼是 ARKit Apple AR

ARKit is Apple's framework for augmented reality on iOS. It provides world tracking (knows device position/orientation), plane detection (walls, tables), light estimation, and face tracking. Developers use ARKit with RealityKit (rendering engine) to build AR experiences: placing 3D models, detecting objects, face filters. ARKit is tightly integrated with iOS hardware: LiDAR on iPad Pro and iPhone 12/13/14/15 enables faster plane detection. Vision Pro (Apple's MR headset) uses ARKit concepts, making ARKit a foundation skill for spatial computing.

❓ 常見問題

What's the difference between ARKit and RealityKit?
ARKit = computer vision (detecting planes, tracking motion). RealityKit = rendering engine + physics. Together: ARKit gives pose, RealityKit renders. ARKit 4.0 and later integrate tightly; RealityKit is the way forward.
Can I build AR apps for both iOS and Android with the same codebase?
Partially. Use Unity + AR Foundation: single codebase, both ARKit and ARCore. Native (Swift + ARKit vs Kotlin + ARCore) = platform-specific code, harder to maintain. Unity is easier but slower.
What's USDZ and why does it matter?
USDZ is Apple's 3D asset format (pixar standard). ARKit optimized for USDZ. Works with Quick Look (Share button shows AR preview). Export from Blender/Maya as USDZ; ARKit loads seamlessly.
How do you detect objects in ARKit?
Vision framework for on-device ML object detection. ARKit provides the camera frame, Vision runs inference, you get bounding boxes. Combine with ARKit anchors to place 3D content.
What's the Vision Pro and how does it relate to ARKit?
Vision Pro is Apple's spatial computer (MR headset). visionOS uses ARKit concepts (world tracking, anchors). ARKit skills transfer to Vision Pro development. Vision Pro = future of Apple AR.
Can older iPhone models run ARKit?
Requires A9 chip or later (iPhone 6s+). Modern feature detection needs A12 (iPhone XS+). ~300M+ iPhones support ARKit. Older devices are mostly phased out.
What's the performance difference between ARKit and RealityKit?
RealityKit is optimized for iOS hardware; SceneKit (older) is slower. RealityKit = native compiled (fast), SceneKit = C++ wrapper (slower). Use RealityKit for new projects.
