During testing the “Bringing advanced speech-to-text capabilities to your app” sample app demonstrating the use of iOS 26 SpeechAnalyzer, I noticed that the language model for the English locale was presumably already downloaded. Upon checking the documentation of AssetInventory, I found out that indeed, the language model can be preinstalled on the system. Can someone from the dev team share more info about what assets are preinstalled by the system? For example, can we safely assume that the English language model will almost certainly be already preinstalled by the OS if the phone has the English locale?

After reading the documentation for TranslationSession and other API methods I got an impression that it will not be possible to use the Translation API with UI elements built with UIKit. You don’t instantiate this class directly. Instead, you obtain an instance of it by adding a translationTask(_:action:) or translationTask(source:target:action:) function to the SwiftUI view containing the content you want to translate So the main question I have to the engineers of mentioned framework is will there be any support for UIKit or app developers will have to rewrite their apps in SwiftUI just to be able to use the Translation API?
