Questions tagged [phasset]

A `PHAsset` is an object in the iOS Photos Framework (aka PhotoKit) that represents an image or video file on the iOS device.

A PHAsset object represents an image or video file that appears in the Apple Photos app, including iCloud Photos content.

To display or edit assets, use the PHAsset class to fetch asset objects for the photos or videos you want to work with. An asset object is immutable and contains only the metadata for the photo or video it represents.
