# reconfigureRows(at:)

Updates the data for the rows at the index paths you specify, preserving the existing cells for the rows.

## Declaration

```swift
func reconfigureRows(at indexPaths: [IndexPath])
```

## Parameters

- `indexPaths`: An array of doc://com.apple.documentation/documentation/Foundation/NSIndexPath objects identifying the items you want to update.

## Discussion

Discussion To update the contents of existing (including prefetched) cells without replacing them with new cells, use this method instead of reloadRows(at:with:). For optimal performance, choose to reconfigure rows instead of reloading rows unless you have an explicit need to replace the existing cell with a new cell. Your cell provider must dequeue the same type of cell for the provided index path, and must return the same existing cell for a given index path. Because this method reconfigures existing cells, the table view doesn’t call prepareForReuse() for each cell dequeued. If you need to return a different type of cell for an index path, use reloadRows(at:with:) instead. If your cells are self-sizing, the table view resizes your cells after reconfiguring them. By default, the table view animates any size or layout changes that are a result of reconfiguration. To reconfigure cells without animation, use UIView’s performWithoutAnimation(_:) when you call this method. Alternatively, to avoid animations when setting specific properties, use performWithoutAnimation(_:) in your cell configuration logic. If your table view uses a custom implementation of UITableViewDataSource, use this method. If your table view uses a diffable data source, use reconfigureItems(_:) (Swift) or reconfigureItems(withIdentifiers:) (Objective-C) on NSDiffableDataSourceSnapshot instead.
