Can it help with camera and microphone permissions?

Yes, it provides boilerplate code for requesting authorization and includes the necessary Info.plist keys for NSCameraUsageDescription and NSMicrophoneUsageDescription.

Does it prevent UI freezing during camera setup?

Absolutely. The skill enforces the best practice of running all AVCaptureSession configurations and start/stop calls on a dedicated background serial queue.

How does it handle device rotation for the camera?

It utilizes the modern iOS 17+ RotationCoordinator API to ensure both the camera preview and the captured media are correctly oriented regardless of device gravity.

What is the benefit of the Zero Shutter Lag (ZSL) implementation?

ZSL uses a ring buffer to capture the frame at the exact moment the user taps the shutter, eliminating the delay typically found in action photography.

Does this skill support SwiftUI integration?

Yes, it includes specific patterns for wrapping AVCaptureVideoPreviewLayer in UIViewRepresentable for seamless use within SwiftUI views.

Mobile Development

Implements high-performance camera capture workflows using modern AVFoundation APIs and responsive capture patterns.

About

Axiom Camera Capture is a specialized Claude Code skill designed to guide developers through the complexities of AVFoundation on Apple platforms. It focuses on implementing robust camera features including photo and video capture, responsive UI patterns like zero-shutter-lag, and modern orientation handling using the RotationCoordinator. Whether building a custom camera UI or managing complex session lifecycles, this skill provides production-ready implementation patterns that prioritize performance and avoid common pitfalls like blocking the main thread or mishandling device interruptions.
