# save(_:commit:)

Saves changes to a reminder by either committing or batching the changes.

```
func save(_ reminder: EKReminder, commit: Bool) throws
```

## Parameters

`reminder`

The reminder to save.

`commit`

A Boolean value that indicates whether to save the reminder immediately or to batch the changes. Passing <doc://com.apple.documentation/documentation/Swift/false> won’t commit changes to the event store until the [`commit()`](/documentation/EventKit/EKEventStore/commit()) method is invoked.

## Discussion

This method raises an exception if `reminder` belongs to another event store.

> Handling Errors in Swift:
> In Swift, this method returns `Void` and is marked with the `throws` keyword to indicate that it throws an error in cases of failure. Call this method in a `try` expression and handle any errors in the `catch` clauses of a `do` statement, as described in [Error Handling](https://docs.swift.org/swift-book/LanguageGuide/ErrorHandling.html) in [The Swift Programming Language](https://docs.swift.org/swift-book/) and `About Imported Cocoa Error Parameters`.

[`commit()`](/documentation/EventKit/EKEventStore/commit())

Commits all unsaved changes to the event store.
