# init(nibNamed:bundle:)

Returns an NSNib object initialized to the nib file in the specified bundle.

## Declaration

```swift
init?(nibNamed nibName: NSNib.Name, bundle: Bundle?)
```

## Parameters

- `nibName`: The name of the nib file, without any leading path information. Inclusion of the .nib extension on the nib file name is optional.
- `bundle`: The bundle in which to search for the nib file. If you specify nil, this method looks for the nib file in the main bundle.

## Return Value

Return Value The initialized NSNib object or nil if there were errors during initialization or the nib file could not be located.

## Discussion

Discussion The NSNib object looks for the nib file in the bundle’s language-specific project directories first, followed by the Resources directory. After the nib file has been loaded, the NSNib object uses the bundle’s resource map to locate additional resources referenced by the nib. If you specified nil for the bundle parameter, the NSNib object looks for those resources in the bundle associated with the class of the nib file’s owner instead. If the nib file does not have an owner, the NSNib object looks for additional resources in the application’s main bundle.
