- Project Overview: We are looking for an experienced iOS engineer to fix a 90-degree rotation issue affecting a foot-scanning flow on iPhone 17 devices. The issue appears in the TrueDepth / camera pipeline and must be resolved without impacting behavior on older devices (iPhone 15/16). This is a focused, technical debugging and implementation task, not a full app build. - Goal: Correct the scan orientation on iPhone 17 while preserving existing functionality on previous iPhone models. - Responsibilities: Analyze the TrueDepth capture pipeline and orientation handling across camera, rendering, and detection layers Identify the root cause of the rotation issue specific to iPhone 17 Implement a robust, device-aware orientation fix (no regressions on older devices) Ensure color preview, depth/point cloud, and detection bounding boxes remain aligned Validate the fix on real devices and document the solution - Required Skills: Strong Swift and iOS camera stack experience AVFoundation, AVCaptureSession, AVCaptureConnection TrueDepth and depth data handling (AVCaptureDepthDataOutput) Debugging camera orientation issues, especially front camera behavior Experience applying orientation transforms correctly - Nice to Have: Metal or MetalPerformanceShaders SceneKit or 3D point cloud rendering Vision / CoreML integration Experience with 3D scanning SDKs (e.g., StandardCyborgFusion or similar) - Deliverables: Code changes that fix rotation on iPhone 17 only No regressions on older iPhone models Short technical write-up explaining the root cause and fix Validation notes from testing on iPhone 17 and previous models - Engagement: Contract-based, long-term task Immediate start preferred Clear scope and fast turnaround

Hi Rajko, Let's create a focused fix to correct the 90-degree rotation in the iPhone 17 TrueDepth foot-scan pipeline while preserving behavior on iPhone 15/16. You have a 90-degree rotation in the iPhone 17 TrueDepth capture pipeline that breaks the foot-scanning flow without affecting iPhone 15/16. I've tracked and fixed front-camera orientation regressions in AVFoundation stacks before—inspecting AVCaptureConnection, depth data alignment, and render transforms to keep color preview, depth/point cloud, and bounding boxes synchronized. I will implement a device-aware orientation transform that triggers only on iPhone 17, validate on real devices, and deliver a short technical write-up explaining root cause and the code change. I've done this with AVCaptureDepthDataOutput and custom render pipelines, delivering fast, clear fixes that avoid regressions. I'm responsive and timezone-flexible. Happy to chat about next steps. Best regards, Saad

A 90 degree rotation bug that only shows up on iPhone 17 is exactly the kind of issue that hides in the camera pipeline. From your description, the foot scan flow works correctly on iPhone 15 and 16, but the TrueDepth output on iPhone 17 is rotated. That points to a change in orientation metadata or front camera behavior rather than the scan logic itself. I have debugged TrueDepth and AVFoundation pipelines where color preview, depth data, and bounding boxes drift or rotate differently across devices. I would start by tracing orientation handling at the AVCaptureConnection level, then verify how depth data and point clouds are transformed before rendering. The fix would be device aware so older models stay untouched. I will validate alignment between RGB, depth, and detection layers on real hardware and document exactly why iPhone 17 behaves differently. Do you already have an iPhone 17 available for testing, or should I plan validation around a specific model variant? Happy to dig into this as soon as you are ready.

Rajko, Just fixed a similar camera pipeline issue on an iPhone 16 project using Swift and AVFoundation. I'm confident we can resolve the 90-degree rotation problem affecting the foot-scanning flow on iPhone 17 devices. We're the perfect fit for this task, given my expertise in iOS camera stack and TrueDepth pipeline optimization. I've worked on various camera-related projects, implementing robust orientation fixes and ensuring seamless integration with rendering and detection layers. I specialize in AVFoundation, AVCaptureSession, AVCaptureConnection, and TrueDepth data handling, ensuring accurate color preview, depth/point cloud, and detection bounding box alignment. Multiple 5-star reviews on complex iOS camera projects demonstrate my ability to deliver high-quality solutions. Happy to schedule a quick call to discuss the project scope and timelines. If you'd like, we can also jump on a free consultation to explore possible solutions. Chris | Lead Developer | Novatech

Hello, I hope you are doing well. I’m an iOS engineer with deep hands-on experience in AVFoundation, TrueDepth data, and front-camera orientation handling. I focus on robustly aligning color previews, depth data, and detection outputs across devices, without introducing regressions. In past projects I diagnosed and fixed orientation/transform issues in the camera pipeline, implemented device-aware transforms, and kept the pipeline stable on older iPhones while addressing new hardware quirks. I’ll apply the same approach here: analyze the capture/render/ML stack, reproduce on iPhone 17, implement a targeted orientation fix, and validate that the fix preserves behavior on iPhone 15/16. I can deliver the code changes to fix rotation specifically on iPhone 17, with a concise technical write-up and testing notes. I’ll begin immediately and aim for a quick turnaround with no regressions on older devices. Best regards, Billy Bryan

Hello, As a developer with a wide range of skills rooted mostly in web development and design, I may not have direct experience fixing an issue specific to iPhone 17 devices. However, my knowledge of languages like Swift and iOS camera stack will make it relatively easy for me to understand the front camera orientation issue you mentioned. My extensive experience in debugging, adapting and troubleshooting software problems, plus the fact that I'm an iOS user myself who's currently using an iPhone 17, puts me in a great place to analyze and solve this problem accurately. Working primarily as a full-stack developer, I've mastered the art of breaking down complex technicalities into manageable components. This plays out well for your project since you require someone capable of diving deep into TrueDepth capture pipelines and identification of the root cause. Additionally, my strong proficiency with AVFoundation and AVCaptureSession ensures that all layers of the camera, rendering, and detection are aligned and work seamlessly post-fix. Though not explicitly mentioned in your requirements, let's touch on "fast turnaround". Having adapted successfully to tight project timelines several times in the past, I assure you that wouldn't be a problem here either. If speed without compromising quality is what you're looking for, then I'm ready to jump into this project immediately- technologies or tools wouldn't be a barrier here; rather just Thanks!

Hello there! Do you want the fix to be implemented entirely within the existing camera pipeline, or is it acceptable to introduce a small device-specific orientation wrapper to handle iPhone 17 independently? I will analyze your TrueDepth capture pipeline, identify the root cause of the 90-degree rotation issue on iPhone 17, and implement a precise, device-aware fix that preserves full functionality on iPhone 15/16, ensuring color previews, depth/point cloud data, and detection bounding boxes remain perfectly aligned, while validating the solution on real devices and providing a concise technical write-up detailing the cause and the implemented fix—would you like me to also include a small test suite to catch any future regressions on new devices? Here's my portfolio for your review: https://www.freelancer.com/u/Penmate Please feel free to message me so we can discuss the project in more detail. Best regards, Bryson Henniger.
