I’m after verybasic proof-of-concept that demonstrates LiDAR-based 3D scanning on iPhone using Swift, ARKit/RealityKit, or any other native approach you find effective. When the app launches it should show a single button; tapping that button starts the LiDAR scan, stopping it generates one STL file (the only required format). Right after processing, the mesh needs to: • display inside the app so I can visually confirm the scan, and • be saved locally for offline access. Would be great if can be uploaded on gdrive if that doesn't add lotof work for this prototype. Performance is important—I’ve tested similar code in “Antigravity” and know the device can handle fast reconstruction, so I expect comparable speed here. No fancy UI, NO splash screens, or extra features; clean Swift code that I can extend later is the goal. Deliverables – please hand over: 1. Xcode project (Swift) that builds and runs on iOS 17+ LiDAR-equipped devices. 2. Working STL export, in-app preview, local save path, and optionally Google Drive upload flow. 3. Brief README with build/run steps and any entitlements or Drive API keys I must add. If this prototype behaves as described, I’ll move straight into a full feature build with you.
