IIRC, the new photos highlights videos pick your best photos using Apple Intelligence. Is there an API or metadata available to use AI and get the best photo out of e.g. 5 similar photos?

iOS 18 adds a specific macro for exposing your search app intent, app entities, etc, to siri but how are you meant to add it to your existing objects without removing it entirely from < iOS 18 users? For example, i get the following error: AssistantIntent(schema:) is only available in iOS 18 or newer. Add @available attribute to enclosing struct. I don't want to do that since i still want to support iOS 17 users with my existing shortcuts. Do i need to duplicate my entire shortcuts model to add the new macro?

From https://www.apple.com/newsroom/2024/06/introducing-apple-intelligence-for-iphone-ipad-and-mac/: Powered by Apple Intelligence, Siri becomes more deeply integrated into the system experience. With richer language-understanding capabilities, Siri is more natural, more contextually relevant, and more personal, with the ability to simplify and accelerate everyday tasks. From https://developer.apple.com/apple-intelligence/: Siri is more natural, more personal, and more deeply integrated into the system. Apple Intelligence provides Siri with enhanced action capabilities, and developers can take advantage of pre-defined and pre-trained App Intents across a range of domains to not only give Siri the ability to take actions in your app, but to make your app’s actions more discoverable in places like Spotlight, the Shortcuts app, Control Center, and more. SiriKit adopters will benefit from Siri’s enhanced conversational capabilities with no additional work. And with App Entities, Siri can understand content from your app and provide users with information from your app from anywhere in the system. Based on this, as well as the video at https://developer.apple.com/videos/play/wwdc2024/10133/ , my understanding is that in order for Siri to be able to execute tasks in applications, those applications must implement the Siri Intents API. Can someone at Apple please clarify: will it be possible for Siri or some other aspect of Apple Intelligence / Core ML / Create ML to take actions in applications which do not support these APIs (e.g. web apps, Citrix apps, legacy apps)? Thank you!
