# init(defaultPartySize:defaultBooking:code:userActivity:)

Initializes the response object with the specified information and user activity object.

```
init(defaultPartySize: Int, defaultBooking defaultBookingDate: Date, code: INGetAvailableRestaurantReservationBookingDefaultsIntentResponseCode, userActivity: NSUserActivity?)
```

## Parameters

`defaultPartySize`

The default size of the user’s party. The value should reflect a reasonable estimate of the number of people the user is likely to have in their party and should be between the restaurant’s stated minimum and maximum values.

`defaultBookingDate`

The default booking date to display to the user. This date should reflect a reasonable estimate of the time that the user might want for a reservation, taking into account the current availability of reservations at the given restaurant.

`code`

The response code indicating your success or failure in handling the intent. For a list of possible values, see [`INGetAvailableRestaurantReservationBookingDefaultsIntentResponseCode`](/documentation/Intents/INGetAvailableRestaurantReservationBookingDefaultsIntentResponseCode).

`userActivity`

The user activity object to use when launching your app. Provide an object if you want to add information that is specific to your app. If you specify `nil`, the system automatically creates a user activity object for you, sets its type to the class name of the intent being handled, and fills it with an [`INInteraction`](/documentation/Intents/INInteraction) object containing the intent and your response.

## Return Value

An initialized response object or `nil` if the object could not be created.
