## Declaration

```swift
func CFTreeAppendChild(_ tree: CFTree!, _ newChild: CFTree!)
```

## Parameters

- `tree`: The tree to which to add newChild.
- `newChild`: The child tree to add to tree. If this parameter is a tree which is already a child of any other tree, the behavior is undefined.

## Discussion

Discussion When a child tree is added to another tree, the child tree is retained by its new parent.
