```

## Parameters

- `title`: The title of the index item. This string corresponds to one of the strings you returned in your doc://com.apple.uikit/documentation/UIKit/UICollectionViewDataSource/indexTitles(for:) method.
- `index`: The index into the array returned by the doc://com.apple.uikit/documentation/UIKit/UICollectionViewDataSource/indexTitles(for:) method that corresponds to the index title.

## Return Value
