# pendingItemsDidChange(completionHandler:)

Tells the file provider extension that the set of pending items has changed.

## Declaration

```swift
optional func pendingItemsDidChange(completionHandler: @escaping @Sendable () -> Void)
```

```swift
optional func pendingItemsDidChange() async
```

## Parameters

- `completionHandler`: A block that you call after you finish processing the changes.

## Discussion

Discussion important: You can implement this method as a synchronous method that takes a completion handler, as shown on this page, or as an asynchronous method that has the following declaration: optional func pendingItemsDidChange() async For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously. The system calls this method whenever the set of pending items changes. It updates the pending set regularly, but only when there are meaningful changes, such as: New items are now pending. The system has successfully synced one or more pending items. The domain version changed when the pending item set wasn’t empty. To enumerate the pending set, create an object that adopts the NSFileProviderEnumerationObserver and NSFileProviderChangeObserver protocols. Then pass this item to the enumeratorForPendingItems() method on a NSFileProviderManager instance for your domain. The system then calls your observer object’s methods when the pending set changes. tip: Calls to the observer object may not happen immediately. Don’t use the pending set to detect changes.
