XCode 27.2 Beta / Claude Code - UI lockups

freeze seems to be tied to claudes use of the gh api command

Thanks for your post.

I personally have not seen that issue with Xcode 27.2 beta from September 16, 2026 Build 27B5019j. Do you have a sysdiagnose?

Do you see any difference instead of killing Xcode to kill the process?

pkill -f "claude-code|@anthropic-ai/claude-code"

Not sure this is the kill command for the process.

Have you filed a bug? Do you have a way to reproduce it or is it happening every single time?

If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?

I do not as of yet. I'm admittedly fairly new to coding with ex code and not sure how to obtain a sysdiagnose. I'm having to force quit XCode everytime this happens.

It seems to happen everytime Claude brings up a Q&A prompt as indicated in the attached screenshot.

Here is the Feedback ID which contains the sysdiagnose

Thank you so much, I appreciate the good looking out for this relative newbie :-)

I can confirm this happens a lot. I'm using Xcode 27.0 and almost every time a "Allow command" dialog appears, Xcode freezes and needs to be restarted.

@effxbe Thanks for jumping on this thread if you have a filed bug, please post the FB number here. Thanks

@effxbe Thanks got routed to the correct team. Please keep an eye on the Feedback Assistant

Same here. Everytime an "Allow command" dialog from Claude agent come up, xcode freezes.

But I also noticed that it is only happening when XCode is on an external Display.

If I'm running XCode on the Macbook screen, even with an external display connected it works fine.

As soon as XCode is moved to the external display (Dell in my case) xcode freezes on every "Allow command" dialog from Claude agent.
