# updateAuthorization(for:descriptor:completionHandler:)

Displays a view to upgrade an accessory with additional technology permissions.

## Declaration

```swift
func updateAuthorization(for accessory: ASAccessory, descriptor: ASDiscoveryDescriptor, completionHandler: @escaping @Sendable ((any Error)?) -> Void)
```

```swift
func updateAuthorization(for accessory: ASAccessory, descriptor: ASDiscoveryDescriptor) async throws
```

## Parameters

- `accessory`: The accessory to update.
- `descriptor`: An updated descriptor that the picker uses to add new technology authorization for the provided accessory.
- `completionHandler`: A block or closure that executes after the picker is shown. The completion handler receives an doc://com.apple.documentation/documentation/Foundation/NSError instance if the upgrade operation encounters an error. In Swift, you can omit the completion handler by calling the method asynchronously and catching any error thrown by the method.
