# NSMetadataQueryAttributeValueTuple

The NSMetadataQueryAttributeValueTuple class represents attribute-value tuples, which are objects that contain the attribute name and value of a metadata attribute.

## Declaration

```swift
class NSMetadataQueryAttributeValueTuple
```

## Overview

Overview Attribute-value tuples are returned by NSMetadataQuery objects as the results in the value lists. Each attribute/value tuple contains the attribute name, the value, and the number of instances of that value that exist for the attribute name.
