# init(windowNibName:owner:)

Returns a window controller initialized with a nib file and a specified owner for that nib file.

## Declaration

```swift
convenience init(windowNibName: NSNib.Name, owner: Any)
```

## Parameters

- `windowNibName`: The name of the nib file (minus the “.nib” extension) that archives the receiver’s window; cannot be nil.
- `owner`: The nib file’s owner; cannot be nil.

## Discussion

Discussion The default initialization turns on cascading, sets the shouldCloseDocument property to false, and sets the autosave name for the window’s frame to an empty string.
