# setDistributionIdentifier(_:forProperty:person:)

Assigns a specific distribution identifier for a person’s multivalue list property so that the group can be used as a distribution list.

## Declaration

```swift
func setDistributionIdentifier(_ identifier: String!, forProperty property: String!, person: ABPerson!) -> Bool
```

## Parameters

- `identifier`: The identifier to be set as the distribution identifier
- `property`: The property whose distribution identifier will be set.
- `person`: The person whose distribution identifier will be.

## Return Value

Return Value true if successful; otherwise, false.

## Discussion

Discussion The default distribution identifier is a multivalue list’s primary identifier. If person is nil, this method raises an exception. Distribution identifiers let you use groups as distribution lists, by indicating which value in a multivalue property should be used when addressing the group. See Address Book Programming Guide for Mac for more detailed discussion.
