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

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

## Declaration

```swift
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 doc://com.apple.sirikit/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 doc://com.apple.sirikit/documentation/Intents/INInteraction object containing the intent and your response.

## Return Value

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