# actionIdentifiers

The identifiers that specify custom actions the app supports for the item.

```
var actionIdentifiers: [String] { get set }
```

## Discussion

The identifiers correspond to the <doc://com.apple.documentation/documentation/BundleResources/Information-Property-List/CoreSpotlightActions/CoreSpotlightActionIdentifier> values you specify in the <doc://com.apple.documentation/documentation/BundleResources/Information-Property-List/CoreSpotlightActions> key of the app’s `Info.plist` file.

When the user selects a custom action on an indexed item, the system launches your app and invokes <doc://com.apple.documentation/documentation/UIKit/UIApplicationDelegate/application(_:continue:restorationHandler:)>. The `userInfo` dictionary of the specified <doc://com.apple.documentation/documentation/Foundation/NSUserActivity> includes the corresponding `Info.plist` entry using the key [`CSActionIdentifier`](/documentation/CoreSpotlight/CSActionIdentifier).
