# renameItem(withIdentifier:toName:completionHandler:)

Renames a document or directory.

## Declaration

```swift
func renameItem(withIdentifier itemIdentifier: NSFileProviderItemIdentifier, toName itemName: String, completionHandler: @escaping @Sendable (NSFileProviderItem?, (any Error)?) -> Void)
```

```swift
func renameItem(withIdentifier itemIdentifier: NSFileProviderItemIdentifier, toName itemName: String) async throws -> NSFileProviderItem
```

## Parameters

- `itemIdentifier`: The item’s persistent identifier.
- `itemName`: The new name of the file or directory, including the file extension.
- `completionHandler`: A block that takes the following parameters:

## Discussion

Discussion important: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: func renameItem(withIdentifier itemIdentifier: NSFileProviderItemIdentifier, toName itemName: String) async throws -> NSFileProviderItem For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously. This method is called when the user renames a document or directory. Override this method to rename the item locally. Your implementation should return immediately. Call the completion handler before performing any network activity or other long-running tasks. Defer these tasks to the background. The renamedItem instance that you pass to the completion handler should match the item’s old file provider item, with only one change: set the filename property to the value passed to the itemName parameter. The user’s ability to rename an item is controlled by the item’s allowsRenaming capability.
