# init(recognizedDataTypes:qualityLevel:recognizesMultipleItems:isHighFrameRateTrackingEnabled:isPinchToZoomEnabled:isGuidanceEnabled:isHighlightingEnabled:)

Creates a scanner for finding data, such as text and machine-readable
codes, in the camera’s live video.

```
@MainActor init(recognizedDataTypes: Set<DataScannerViewController.RecognizedDataType>, qualityLevel: DataScannerViewController.QualityLevel = .balanced, recognizesMultipleItems: Bool = false, isHighFrameRateTrackingEnabled: Bool = true, isPinchToZoomEnabled: Bool = true, isGuidanceEnabled: Bool = true, isHighlightingEnabled: Bool = false)
```

## Parameters

`recognizedDataTypes`

The types of data that the data scanner
identifies in the live video.

`qualityLevel`

The level of resolution to scan that depends on the size
of the items.

`recognizesMultipleItems`

A Boolean value that indicates whether the
scanner identifies all items in the live video.

`isHighFrameRateTrackingEnabled`

A Boolean value that determines the
frequency that the scanner updates the geometry of recognized items.

`isPinchToZoomEnabled`

A Boolean value that indicates whether people can
use a two-finger pinch-to-zoom gesture.

`isGuidanceEnabled`

A Boolean value that indicates whether the scanner
provides help to a person when selecting items.

`isHighlightingEnabled`

A Boolean value that indicates whether the
scanner displays highlights around recognized items.
