# enumerateEvents(matching:using:)

Finds all events that match a given predicate and calls a given callback for each event found.

## Declaration

```swift
func enumerateEvents(matching predicate: NSPredicate, using block: @escaping EKEventSearchCallback)
```

## Parameters

- `predicate`: A search predicate created with [doc://com.apple.eventkit/documentation/EventKit/EKEventStore/predicateForEvents(withStart:end:calendars:)](eventkit/ekeventstore/predicateforevents(withstart:end:calendars:).md).
- `block`: The closure to call for each event. The callback must match the signature defined by [doc://com.apple.eventkit/documentation/EventKit/EKEventSearchCallback](eventkit/ekeventsearchcallback.md).

## Discussion

Only committed events are included in the enumeration. To include events saved using [save(_:span:commit:)](save(_:span:commit:).md) with the `commit` parameter set to [false](../../swift/false.md), call [commit()](commit().md) first.

This method is synchronous. For asynchronous behavior, run the method on another thread with [dispatch_async](../../dispatch/dispatch_async.md) or [Operation](../../foundation/operation.md).
