## Overview

Overview LanguageModelFeedback is a namespace with  structures for describing feedback in a consistent way. LanguageModelFeedback.Sentiment describes the sentiment of the feedback, while LanguageModelFeedback.Issue offers a standard template for issues. Given a model session, use logFeedbackAttachment(sentiment:issues:desiredOutput:) to produce structured feedback. let session = LanguageModelSession() let response = try await session.respond(to: "What is the capital of France?")

// Create feedback for a problematic response. let feedbackData = session.logFeedbackAttachment(     sentiment: LanguageModelFeedback.Sentiment.negative,     issues: [         LanguageModelFeedback.Issue(             category: .incorrect,             explanation: "The model provided outdated information"         )     ],     desiredOutput: Transcript.Entry.response(...) )
