# requestState(for:)

Retrieves the state of a region asynchronously.

## Declaration

```swift
func requestState(for region: CLRegion)
```

## Parameters

- `region`: The region with the state you want to know. This object needs to be an instance of one of the standard region subclasses that doc://com.apple.corelocation/documentation/CoreLocation provides, such as doc://com.apple.corelocation/documentation/CoreLocation/CLCircularRegion or doc://com.apple.corelocation/documentation/CoreLocation/CLBeaconRegion. You can’t use this method to determine the state of custom regions you define yourself.

## Discussion

Discussion This method performs the request asynchronously and delivers the results to the location manager’s delegate. You must implement the locationManager(_:didDetermineState:for:) method in the delegate to receive the results. If the region parameter contains an unknown type of region object, this method does nothing. If a compatible iPad or iPhone app calls this method when running in visionOS, the method does nothing.
