From c33481b56dd64acaa3402167670c48a5fb1f4abc Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 25 Apr 2025 15:05:48 +0000 Subject: [PATCH 01/11] feat: Add backend toggle for Google AI/Vertex AI in FirebaseAISample Adds a picker UI to the main `FirebaseAISample` screen allowing users to select between Google AI and Vertex AI backends. - Introduced an `AIBackend` enum to represent the choices. - Added a `@State` variable in `FirebaseAISampleApp` to manage the selection. - Added a `Picker` in `ContentView` bound to the state variable. - Passed the selected backend down to each sample view (`Summarize`, `PhotoReasoning`, `Chat`, `FunctionCalling`, `Imagen`). - Updated the ViewModels for each sample to accept the backend choice and initialize `FirebaseAI.firebaseAI(backend:)` accordingly. - Refactored the `AIBackend` enum to a common location. --- .../Screens/ConversationScreen.swift | 36 +++++++---- .../ViewModels/ConversationViewModel.swift | 18 ++++-- .../FirebaseAISample/Common/AIBackend.swift | 23 +++++++ firebaseai/FirebaseAISample/ContentView.swift | 62 +++++++++++++------ .../FirebaseAISampleApp.swift | 14 ++++- .../Screens/FunctionCallingScreen.swift | 34 ++++++---- .../ViewModels/FunctionCallingViewModel.swift | 18 ++++-- .../Screens/PhotoReasoningScreen.swift | 13 +++- .../ViewModels/PhotoReasoningViewModel.swift | 27 +++++--- .../Screens/SummarizeScreen.swift | 13 +++- .../ViewModels/SummarizeViewModel.swift | 28 ++++++--- firebaseai/ImagenScreen/ImagenScreen.swift | 13 +++- firebaseai/ImagenScreen/ImagenViewModel.swift | 24 +++++-- 13 files changed, 240 insertions(+), 83 deletions(-) create mode 100644 firebaseai/FirebaseAISample/Common/AIBackend.swift diff --git a/firebaseai/ChatSample/Screens/ConversationScreen.swift b/firebaseai/ChatSample/Screens/ConversationScreen.swift index 8d7c3c1a8..68109dfdb 100644 --- a/firebaseai/ChatSample/Screens/ConversationScreen.swift +++ b/firebaseai/ChatSample/Screens/ConversationScreen.swift @@ -15,10 +15,14 @@ import FirebaseAI import GenerativeAIUIComponents import SwiftUI +// Assuming AIBackend is accessible (moved to Common/AIBackend.swift) struct ConversationScreen: View { + // Add backend property, though ViewModel is injected via environment + let backend: AIBackend + @EnvironmentObject -
