# NSMapRemove(_:_:)

Removes a key and corresponding value from the specified table.

```
func NSMapRemove(_ table: NSMapTable<AnyObject, AnyObject>, _ key: UnsafeRawPointer?)
```

## Discussion

If `key` matches a key already in `table`, this function releases the preexisting key and its corresponding value.
