# interfaceParametersDescription()

Returns a human-readable string describing the data that SiriKit displays to the user when you handle an intent.

```
func interfaceParametersDescription() -> String
```

## Discussion

If you provide an Intents UI app extension, you can customize all or some of the interface that SiriKit displays to the user for a given intent. The information displayed by SiriKit is different for each intent, and can change in the future. During development, use this method to retrieve a human-readable description of the contents of the <doc://com.apple.documentation/documentation/Intents/INParameter> objects that SiriKit intends to display for the current intent. Use that information to plan your custom interface.

For information about customizing the Siri and Maps interfaces, see <doc://com.apple.documentation/documentation/SiriKit/creating-an-intents-app-extension>.
