# startingToken

An opaque token that indicates a point in history in the user’s Contacts database.

## Declaration

```swift
var startingToken: Data? { get set }
```

## Discussion

Specify [nil](../../objectivec/nil-227m0.md) to receive a [CNChangeHistoryDropEverythingEvent](../cnchangehistorydropeverythingevent.md), followed by an add event for every contact and group in the Contacts database.

Save the [currentHistoryToken](../cnfetchresult/currenthistorytoken.md) from a successful fetch result in your app, then specify it here to receive changes after that point in history.
