class ENExposureWindowOverview
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.
