# 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:).
- `block`: The closure to call for each event. The callback must match the signature defined by doc://com.apple.eventkit/documentation/EventKit/EKEventSearchCallback.

## Discussion

Discussion Only committed events are included in the enumeration. To include events saved using save(_:span:commit:) with the commit parameter set to false, call commit() first. This method is synchronous. For asynchronous behavior, run the method on another thread with dispatch_async or Operation.
