# DataDetector.Options

A set of options you can use to refine the behavior of text scanning, and better interpret the semantic domain of the matches.

## Declaration

```swift
struct Options
```

## Overview

Overview These properties are only hints, so it’s best to not make assumptions about how the framework uses them: Set documentDate to the creation date of the scanned string, such as a text message reception date. The default is now. Set documentTimeZone to the time zone matching the documentDate. The default is a person’s current time zone. Set documentLanguageCode to the language code of the scanned string, for example, “en” for English. Only set this property if you know the target language with a high degree of confidence; otherwise, set to nil. Set documentRegion to the region relevant to the scanned string, if any. Only set this property if you know the region with a high degree of confidence; otherwise, set to nil.
