# CLLocationSourceInformation

Information about the source that provides a location.

## Declaration

```swift
class CLLocationSourceInformation
```

## Overview

Overview CLLocationSourceInformation contains information about the source that provides a CLLocation instance, such as instances that locationManager(_:didUpdateLocations:) delivers. For example, an app may choose to check the source information and reject locations if the isSimulatedBySoftware property is true when the developer isn’t debugging or testing the app.
