Hi @owenzhao, thanks for reaching out.

We've attempted to reproduce the issue using the repo steps you provided, but we're unable to replicate it on our end with the following configuration:

• Copilot for Xcode: 0.43.139
• Xcode: 26.0
• macOS: 26.0 (also tested on macOS 15.0)

Could you please share the log file located at ~/Library/Logs/GitHubCopilot/github-copilot-for-xcode.log? A screenshot or screen recording demonstrating the issue would also be helpful for diagnosing and resolving the problem more effectively.

Thanks!

I can't get it now. I will reopen this if it happens again.

I got it again. See this video. The selected code needs to be having error in. And that makes Xcode keeps getting focus, I think.

Copilot for Xcode: 0.43.140
