Use when implementing ANY computer vision feature — image analysis, pose detection, person segmentation, subject lifting, text recognition, barcode scanning.
Apple Vision Framework for computer vision tasks: subject segmentation, pose detection, text recognition, barcode scanning, and document processing. Covers 13+ Vision APIs across subject lifting, hand/body pose, person segmentation, text OCR, barcode detection, and document scanning with decision trees for choosing the right tool Includes 15 production patterns: combining APIs to exclude hands from objects, real-time gesture recognition, multi-person segmentation, fitness action classification, and live camera scanning Requires iOS 14+ minimum; instance masks and 3D body pose need iOS 17+; DataScannerViewController requires iOS 16+ All Vision processing must run on background queues to prevent UI freezing; confidence scores must be checked before using landmarks to avoid unreliable detections Computer Vision You MUST use this skill for ANY computer vision work using the Vision framework.
