Rate limit and chat window issues

从附件 github-copilot-for-xcode.log 开始，使用 Copilot for Xcode 0.47.0、Xcode 26.3 和 macOS 26.3.1 重现报告的行为。当速率限制导致的中断、空白聊天窗口以及源代码编辑器键盘焦点问题分别被隔离并得到处理，或被拆分为可执行的 issue 时，这项工作就完成了。

Describe the bug

I have been experiencing a couple of issues that are extremely annoying. The first issue I have is that interations keep stopping due to a supposed rate limit being reached, but as a Github Copilot Pro+ subscriber, I've never had this issue under Visual Studio Code, only on Xcode. I can usually quit out of Xcode, and restart and things are fine again.

The second issue is that the chat window appears to go "blank" or rather, it reverts back to the original screen before starting a new chat, although copilot appears to be working in the background. Sometimes the chat randomly comes back, sometimes not.

I also noticed that when copilot is editing a source code file, and I'm working elsewhere, the source code window "steals" my keyboard inputs and I end up screwing up whatever copilot was editing.

Versions

• Copilot for Xcode: 0.47.0
• Xcode: 26.3
• macOS: 26.3.1

Steps to reproduce
Rate Limit Issue:

1. Be me, working as normal, then get hit with a rate limit error.

Blank Chat Window:

1. Same as above.

Source Code Editor Issue:

1. Be in the middle of an iteration that requires copilot to edit source code, and have any other application open at the same time.
2. try typing in your other application--if the source code window goes active automatically, whatever you're typing is captured by the source code editor instead of the other app.

Screenshots

This is the screen that the chat reverts to randomly:
