AVCamPhotoFilter: Version 3.0, 2017-09-19
Account for Metal APIs that now return optionals. Minor storyboard tweaks. AVCamPhotoFilter demonstrates how to use the AVFoundation capture API to capture photos and use CoreImage to apply a filter to the captured photo and the live preview. It shows how to properly propagate sample buffer attachments and attributes, including EXIF and color space information (like wide gamut). Signed-off-by: Liu Lantao <liulantao@gmail.com>
