//
// SampleCode.xcconfig
//
// The `SAMPLE_CODE_DISAMBIGUATOR` configuration is to make it easier to build
// and run a sample code project. Once you set your project's development team,
// you'll have a unique bundle identifier. This is because the bundle identifier
// is derived based on the 'SAMPLE_CODE_DISAMBIGUATOR' value. Do not use this
// approach in your own projects—it's only useful for sample code projects because
// they are frequently downloaded and don't have a development team set.

# AVCam-iOS: Using AVFoundation to Capture Photos and Movies # AVCam-iOS
AVCam demonstrates how to use the AVFoundation capture API to record movies and capture photos. The sample has a record button for recording movies, a photo button for capturing photos, a Live Photo mode button for enabling Live Photo capture, a capture mode control for toggling between photo and movie capture modes, and a camera button for switching between front and back cameras (on supported devices). AVCam runs only on an actual device, either an iPad or iPhone, and cannot be run in Simulator. AVCam demonstrates how to use the AVFoundation capture API to record movies and capture photos.
## Overview
The sample has a record button for recording movies, a photo button for capturing photos, a Live Photo mode button for enabling Live Photo capture, a Depth Data delivery button for enabling depth data delivery in capture, a capture mode control for toggling between photo and movie capture modes, and a camera button for switching between front and back cameras (on supported devices). AVCam runs only on an actual device, either an iPad or iPhone, and cannot be run in Simulator.
## Requirements ## Requirements
