# MTLCommandBufferEncoderInfo

A container that provides additional information about a runtime failure a GPU encounters as it runs the commands in a command buffer.

## Declaration

```swift
protocol MTLCommandBufferEncoderInfo : NSObjectProtocol
```

## Overview

Overview To create a command buffer that generates additional information (when a GPU encounters an error running it), configure an MTLCommandBufferDescriptor instance’s errorOptions property. For information about how to retrieve the information from an MTLCommandBuffer instance, see its error property.
