```

## Discussion

Value is an <doc://com.apple.documentation/documentation/Foundation/NSNumber> object configured as an <doc://com.apple.documentation/documentation/ObjectiveC/NSUInteger>. Chapter numbering uses zero-based indexing. For example, to display the first chapter in the Now Playing item as “Chapter 1,” set the chapter number to `0`.
