# kCLErrorUserInfoAlternateRegionKey

A key in the user information dictionary of an error relating to a delayed region-monitoring response.

```
let kCLErrorUserInfoAlternateRegionKey: String
```

## Discussion

This key is included in an error of type [`regionMonitoringResponseDelayed`](/documentation/CoreLocation/CLError-swift.struct/regionMonitoringResponseDelayed). The value is a [`CLRegion`](/documentation/CoreLocation/CLRegion) object containing the region that location services can monitor more effectively.
