```

## Parameters

- `flow`: The NEFilterSocketFlow to update the verdict for.
- `verdict`: An doc://com.apple.networkextension/documentation/NetworkExtension/NEFilterDataVerdict instance. This must be an doc://com.apple.networkextension/documentation/NetworkExtension/NEFilterDataVerdict/allow() or doc://com.apple.networkextension/documentation/NetworkExtension/NEFilterDataVerdict/drop() verdict, or a data verdict created with the Swift initializer or ObjectiveC type method, doc://com.apple.networkextension/documentation/NetworkExtension/NEFilterDataVerdict/init(passBytes:peekBytes:).
