# NSNextMapEnumeratorPair(_:_:_:)

Returns a Boolean value that indicates whether the next map-table pair in the enumeration are set.

## Declaration

```swift
func NSNextMapEnumeratorPair(_ enumerator: UnsafeMutablePointer<NSMapEnumerator>, _ key: UnsafeMutablePointer<UnsafeMutableRawPointer?>?, _ value: UnsafeMutablePointer<UnsafeMutableRawPointer?>?) -> Bool
```

## Return Value

Return Value false if enumerator has already iterated over all the elements in the table that enumerator is associated with; otherwise, sets key and value to match the next key-value pair in the table and returns true.
