通过 Apple 的基础模型框架访问 Gemini API 时，向模型提供工具

import FoundationModels
import FirebaseCore
import FirebaseAILogic

// Initialize the Gemini Developer API backend service.
let ai = FirebaseAI.firebaseAI(backend: .googleAI())
// Initialize a `geminiLanguageModel` with a Gemini model that supports your use case.
let model = ai.geminiLanguageModel(
  name: "GEMINI_MODEL_NAME",
  // Provide Google Search as a tool that the model can use to generate its response.
  serverTools: [GeminiTool.googleSearch()]
)

let session = LanguageModelSession(model: model)
let response = try await session.respond(to: "What is the weather in Toronto today?")
for entry in response.transcriptEntries {
  if case let .response(responseEntry) = entry {
    if let groundingMetadata = responseEntry
        .metadata["groundingMetadata"] as? GroundingMetadata {
      for chunk in groundingMetadata.groundingChunks {
        let webChunk = chunk.web
        // use the webChunk
      }
    }
  }
}

// Make sure to comply with the "Grounding with Google Search" usage requirements,
// which includes how you use and display the grounded result
