This is a focused implementation guide for building custom camera interfaces with AVFoundation instead of using the system picker. It walks you through the full stack: session setup, photo and video capture, handling device rotation with RotationCoordinator, and managing interruptions like phone calls. The skill emphasizes responsive capture UX and zero-shutter-lag techniques, which is exactly the kind of detail you need when the built-in camera UI won't cut it. With 945 GitHub stars and passing all three security audits, it's a solid choice if you're building anything that needs granular control over camera quality, switching between devices, or custom capture flows.
