SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides developers through implementing a robust, production-ready iOS camera capture flow using AVFoundation, covering session setup, orientation handling, and responsive capture UX.

Core Features & Use Cases

  • Session setup with AVCaptureSession, inputs and outputs for photos and video.
  • Rotation handling with RotationCoordinator to keep previews and captures correctly oriented across device orientations.
  • Responsive capture patterns to reduce shutter-lag, handle interruptions, and support front/back switching.
  • Example use cases include building a custom camera UI in a photo app, recording videos with optional audio, and ensuring smooth user experience under rotation and multitasking.

Quick Start

Use the camera-capture skill to initialize a basic AVCaptureSession, add a back camera input, and present a live preview in a SwiftUI view.

Frequently Asked Questions about camera-capture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up an AVCaptureSession for custom iOS camera capture?▼

To set up iOS camera capture, initialize an AVCaptureSession on a dedicated session queue, add back camera inputs, and configure photo or video outputs within your SwiftUI view for live preview.

How do I handle device rotation during AVFoundation camera preview?▼

AVFoundation camera rotation handling uses a RotationCoordinator to keep live previews and captured outputs correctly oriented across changing device orientations without manual interface adjustments.

What's the best way to reduce shutter lag in Swift camera capture?▼

Reducing shutter lag in Swift camera capture involves tracking session readiness and applying optional deferred processing, which maintains responsive UX during photo or video capture.

Can I switch between front and back cameras without restarting the AVCaptureSession?▼

Front and back camera switching is supported within an active AVCaptureSession workflow, handling input reconfiguration dynamically while maintaining continuous preview responsiveness.

Does AVFoundation camera capture handle audio interruptions and multitasking?▼

AVFoundation camera capture handles interruptions and multitasking by enforcing a dedicated session queue and readiness tracking, ensuring the capture workflow resumes properly after pauses.

Why do I need a dedicated session queue for iOS camera capture?▼

A dedicated session queue is needed for iOS camera capture to prevent blocking the main thread during AVCaptureSession configuration, ensuring smooth UI performance during setup and capture.
