# weakToStrongObjects()

Returns a new map table object which has weak references to the keys and strong references to the values.

## Declaration

```swift
class func weakToStrongObjects() -> NSMapTable<KeyType, ObjectType>
```

## Return Value

Return Value A new map table object which has weak references to the keys and strong references to the values.

## Discussion

Discussion Use of weak-to-strong map tables is not recommended. The strong values for weak keys which get zeroed out continue to be maintained until the map table resizes itself.
