# detectValues(for:inItemSet:completionHandler:)

Requests that the data detection system identify the types of data that you specify for the pasteboard items, and provide the values that it matches to your closure.

## Declaration

```swift
func detectValues(for keyPaths: Set<PartialKeyPath<UIPasteboard.DetectedValues>>, inItemSet itemSet: IndexSet?, completionHandler: @escaping (Result<[UIPasteboard.DetectedValues], any Error>) -> ())
```

## Parameters

- `keyPaths`: A set of key paths you use to indicate which types of data you want the data detection system to match.
- `itemSet`: A set of indexes you provide to indicate which pasteboard items the data detection system inspects to detect values.
- `completionHandler`: A closure you provide to process values the data detection system matches, or to handle errors.

## Discussion

Discussion Because this method gives the app access to the values it detects in a pasteboard item, the system notifies the user about reading the contents of the pasteboard.
