LanguageModelSession.DynamicProfile
protocol · iOS 27.0+ · SDK 27.1
protocol DynamicProfileA dynamic profile that contains one or more profiles. A dynamic profile is the top-level coordination layer that manages profiles. It determines which ``Profile`` is in an active state and allows a ``LanguageModelSession`` to switch between entirely different configurations as app state changes. A body must resolve to a single profile. ``DynamicInstructions`` declares what content and tools the model sees, and ``Profile`` binds that content to how a single configuration runs. That configuration includes details like the model to use, temperature, reasoning level, and so on. ```swift struct PresentationProfile: LanguageModelSession.DynamicProfile { // The data source for the profile. var isEditingImage = true var isEditingAnimation = false // Determine which profile to load based on the current state. var body: some LanguageModelSession.DynamicProfile { if isEditingImage { // Use the editing image profile. } else if isEditingAnimation { // Use the editing animation profile. } else { // Use the default profile. } } } ``` Use ``historyTransform(_:)`` to perform stateless transcript transforms. This allows you to modify the transcript that's sent to the model, but doesn't impact the global transcript state. For example, the request might only need the last twenty entries instead of the full transcript: ```swift Profile { // The instructions and tools necessary for the task. } .historyTransform { history in Array(history.suffix(20)) } ```
