# horizontalAccuracy

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

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

## 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`.
