On iOS (tested on iPhone 13 Pro Max), the app displays interactive 3D GLB models but fails to load USDZ files entirely. While AR functionality works seamlessly on Android using Scene Viewer with GLB models, the AR feature does not activate on iOS—the USDZ model neither loads nor triggers AR mode, despite proper configuration. The iOS implementation includes the required Info.plist camera permission (NSCameraUsageDescription) and verified USDZ file integration in Xcode’s asset catalog. The GLB model renders interactively in the 3D viewer, but tapping the AR button yields no response, contrasting with Android’s successful AR experience. This suggests platform-specific limitations in USDZ handling or AR activation within the package for IOS.
