Declaration
var deliveryMode: PHVideoRequestOptionsDeliveryMode { get set }Discussion
Use this property to tell Photos to provide a video quickly (possibly sacrificing image quality) or to provide a high-quality video (possibly sacrificing speed). This option applies only when requesting the current version of the video (that is, only when the version property is PHVideoRequestOptionsVersion.current).
The default option is PHVideoRequestOptionsDeliveryMode.automatic. See PHVideoRequestOptionsDeliveryMode.
