UITableViewDropItem missing in Xcode 16?

Following instructions from ChatGPT, I'm trying to rearrange the order of rows in a UITableView.

- (void)tableView:(UITableView *)tableView performDropWithCoordinator:(id<UITableViewDropCoordinator>)coordinator {
	 NSIndexPath *destinationIndexPath = coordinator.destinationIndexPath ?: [NSIndexPath indexPathForRow:self.items.count inSection:0];
	
	 [tableView performBatchUpdates:^{
		  for (UITableViewDropItem *dropItem in coordinator.items) {
				NSString *movedItem = dropItem.dragItem.localObject;
				if (movedItem) {
					 NSIndexPath *sourceIndexPath = dropItem.sourceIndexPath;
					 if (sourceIndexPath) {
						  [self.items removeObjectAtIndex:sourceIndexPath.row];
						  [self.items insertObject:movedItem atIndex:destinationIndexPath.row];
						  [tableView moveRowAtIndexPath:sourceIndexPath toIndexPath:destinationIndexPath];
					 }
				}
		  }
	 } completion:nil];
}

Xcode is complaining that UITableViewDropItem does not exist.

The class is in all the documentation, it is just not showing up when needed!

Suggestions?
