Copilotに日本語で質問すると、英語で答えが返ってくる。設定で変更可能か？

不可であれば自動的に言語を判別するか、設定で言語を設定できるように変更してほしい。

Hello @yajimaru,

Thank you for your question about GitHub Copilot's language settings in Xcode.

Currently, GitHub Copilot doesn't have a built-in setting to explicitly change the response language in Xcode. When you ask questions in Japanese, Copilot tends to respond in English by default.

While there isn't a direct language setting, here are a few workarounds you might try:

1. Explicitly request Japanese responses: Start your prompts with instructions like "Please respond in Japanese" or "日本語で回答してください" to guide Copilot to respond in your preferred language.

2. Use custom AI models: If you have a Copilot Pro subscription, you can try different AI models that might handle Japanese better. In Xcode, click on the model selector at the bottom of the chat panel (if available) and try models like Claude or GPT-4.

3. Prompt engineering: Frame your questions in a way that makes it clear you want responses in Japanese. For example: "以下の質問に日本語で答えてください: [your question]".

Your suggestion about automatic language detection or a language setting option is excellent feedback. I'll make sure this request is shared with the GitHub Copilot team for consideration in future updates.

If you're working with code, note that the code suggestions themselves should work regardless of the explanation language, but I understand how important it is to get explanations in your preferred language.

Would you like me to provide any additional information about using GitHub Copilot in Xcode?

I was able to successfully follow the steps you taught me.

However, there are two problems.

1. I have to enter the instructions every time.
2. Ask mode requires instructions, but Agent mode does not.

The problem occurs in Ask mode. It is time-consuming to give instructions to set the language to Japanese each time, so I would like the language to be set to Japanese automatically like in Agent mode.

1-1. If instructions are given → expected response is obtained

1-2. Give instructions for future responses to be in Japanese

1-3. Request the same information → not answered correctly

2-1. In Agent mode, answers are given in Japanese without instructions.
