application(_:handlerFor:)

Declaration

@MainActor optional func application(_ application: NSApplication, handlerFor intent: INIntent) -> Any?

Parameters

• application:

  The shared app object.

• intent:

  The intent object that represents the request coming from the system.

Discussion

Siri invokes this method on the main queue when it wants to process one of your app’s supported intents. To indicate the intents that your app supports, populate the INIntentsSupported array in your app target’s Info.plist file.

In your delegate’s implementation of this method, check the intent parameter’s type and return a custom object that adopts the corresponding handling protocol. For example, if intent is an instance of INPlayMediaIntent, return an object that adopts INPlayMediaIntentHandling. Only use the provided intent to determine which handler to return; don’t use it to initialize the handler and don’t store a reference to it. SiriKit updates the intent throughout the request to incorporate information the user provides. For more information, see Dispatching intents to handlers.
