# interfaceParametersDescription()

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

## Declaration

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

## Discussion

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 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 Creating an Intents App Extension.
