# openExtensionsSettings(forIdentifiers:completionHandler:)

Presents the extensions pane from Safari Settings.

```
class func openExtensionsSettings(forIdentifiers extensionIdentifiers: [String], completionHandler: (@MainActor @Sendable ((any Error)?) -> Void)? = nil)
```

```
class func openExtensionsSettings(forIdentifiers extensionIdentifiers: [String]) async throws
```

## Parameters

`extensionIdentifiers`

An array of extension identifiers. If the value is a single identifier, Settings opens to that extension’s detail view. If you specify multiple identifiers, Settings opens to the Safari Extensions pane with the specified extensions selected.

`completionHandler`

A block the system calls after the operation completes, with an optional error parameter.

- error: `nil` if Safari Extensions Settings opens successfully; otherwise, an error that indicates the reason for the failure.

## Discussion

The method returns an error unless you call it while your app is in the foreground.
