# init(conversationIdentifier:unread:)

Initialize a @c CPMessageGridItemConfiguration for use in a @c CPListTemplate.

## Declaration

```swift
init(conversationIdentifier: String, unread: Bool)
```

## Parameters

- `conversationIdentifier`: A value meaningful to your app to identify this conversation. This identifier is not directly displayed to the user; rather, when the user selects this grid item, SiriKit will pass this identifier back to your app for your own use.
- `unread`: A Boolean value indicating whether the item shows an unread indicator. The default value of this property is @c NO.
