init(session: MSSession)
```

- `session`: The session object tracking an updatable exchange of messages.

## Return Value

## Discussion

Discussion Use this initializer to create an updatable message. Messages that are part of a session receive special treatment by the Messages app. When the app receives a message that is part of an existing session, the previous message is moved to the bottom of the transcript and updated with the new message’s content.
