## Declaration

func latestPackedChannels() -> NSDKAsyncState<SceneSegmentationResult, AwarenessError>

#### Summary

Retrieves the latest packed semantic channels data.
This method returns a multi-channel image where each channel represents a different
semantic category. Packed channels provide an efficient way to access multiple
semantic classifications in a single image, reducing the need for multiple API calls.

#### Returns

An NSDKAsyncState containing either the latest SceneSegmentationResult,
  or an AwarenessError.

#### Packed Channels Format

The packed channels image contains multiple semantic categories encoded as separate
channels in a single image. Each channel corresponds to a semantic category, and
pixel values represent classification confidence or probability scores.

#### Performance Benefits

Using packed channels is more efficient than calling `latestConfidence` multiple
times, as it reduces the number of API calls and data transfers required.
