44.14 Adding a Data Class to SiriPhoto

When SiriKit launches the SiriPhoto app in response to a successful photo search, it will pass the app an NSUserActivity instance. The app will need to handle this activity and use the intent response it contains to extract the matching photo from the library. The photo image will, in turn, need to be stored as a published observable property so that the content view is always displaying the latest photo. These tasks will be performed in a new Swift class declaration named PhotoHandler.

Add this new class to the project by right-clicking on the Shared folder in the project navigator panel and selecting the New File… menu option. In the template selection panel, choose the Swift File option before clicking on the Next button. Name the new class PhotoHandler and click on the Create button.

import SwiftUI

import Combine

import Intents
