# distance(between:and:distanceType:)

Calculates the distance between two strings in the vocabulary space.

## Declaration

```swift
@nonobjc func distance(between firstString: String, and secondString: String, distanceType: NLDistanceType = .cosine) -> NLDistance
```

## Parameters

- `firstString`: A string in the embedding vocabulary.
- `secondString`: Another string in the embedding vocabulary.
- `distanceType`: A means of calculating distance that determines which formula the method uses to evaluate the distance between firstString and secondString.

## Return Value

Return Value The distance associated with distanceType.
