# InferenceValue

A value that an inference function accepts as input or produces as output.

## Declaration

```swift
struct InferenceValue
```

## Mentioned in

Integrating on-device AI models in your app with Core AI

## Overview

Overview An InferenceValue wraps either an NDArray or a pixel buffer, and you retrieve it after inference using the ndArray property.
