sampleBuffer
The depth data captured at this synchronization point.
Declaration
var sampleBuffer: CMSampleBuffer { get }Discussion
Note that if the sampleBufferWasDropped property is true, this CMSampleBuffer object does not contain pixel data (instead, it contains only metadata).
This value is equivalent to that provided by the captureOutput(_:didOutput:from:) or captureOutput(_:didDrop:from:) delegate method when using a video data output without a data output synchronizer.
