# ENExposureWindow

A set of scan events from observed beacons within a time span.

## Declaration

```swift
class ENExposureWindow
```

## Overview

Overview important: This property is available in iOS 12.5, and in iOS 13.7 and later. An exposure window contains information about a potential exposure in a 30–minute interval. The system returns an array of exposure windows through the completion handler when the app invokes getExposureWindows(summary:completionHandler:). Exposure windows are only available when an app specified an ENAPIVersion of 2 in the app’s Info.plist file.
