# removeManagedReference(_:withOwner:)

Notifies the JavaScriptCore virtual machine that a previously registered object relationship no longer exists.

## Declaration

```swift
func removeManagedReference(_ object: Any!, withOwner owner: Any!)
```

## Parameters

- `object`: The object formerly referenced by the JavaScript memory management graph.
- `owner`: The other object responsible for the lifetime of the reference.

## Discussion

Discussion Use this method to deregister object relationships recorded using the addManagedReference(_:withOwner:) method. The JavaScript garbage collector continues to scan any references that were reported to it until you use this method to remove those references.
