# horizontalAccuracy

The radius of uncertainty for the location, measured in meters.

## Declaration

```swift
var horizontalAccuracy: CLLocationAccuracy { get }
```

## Discussion

Discussion The location’s latitude and longitude identify the center of the circle, and this value indicates the radius of that circle. A negative value indicates that the latitude and longitude are invalid. Special Considerations In iOS, this property is declared as nonatomic. In macOS, it is declared as atomic.
