# unsupported(forReason:)

Creates a result that requires the user to confirm the request, because your app is unable to support the current request.

```
class func unsupported(forReason reason: INStartCallCallRecordToCallBackUnsupportedReason) -> Self
```

## Parameters

`reason`

The reason that the callback request isn’t supported. For a list of possible values, see [`INStartCallCallRecordToCallBackUnsupportedReason`](/documentation/Intents/INStartCallCallRecordToCallBackUnsupportedReason).

## Return Value

A new [`INStartCallCallRecordToCallBackResolutionResult`](/documentation/Intents/INStartCallCallRecordToCallBackResolutionResult) object.

## Discussion

Use this method to create a resolution result object when your app doesn’t support the intent parameter for the specified reason.
