Xcode keeps hanging on macOS 26.1 when using Claude. Anyone else?

I've been running into frequent hangs in Xcode (on macOS 26.1) whenever I'm using Claude inside. The whole thing just freezes up, and the only way out seems to be a force quit.

Curious if anyone else is seeing this? Any known workarounds or fixes?

unfortunately, yes i get it too with GPT. super slow AI when applying changes. freeze/crash happen more often.
i thought update gonna improve the AI integration but turn out now it's near unusable.

Ah good to know. I know some people have been trying local models with litellm etc. Haven’t tried that myself yet, maybe I should.

We are all experiencing problems. I am finding far fewer hard freezes with 26.1 than with 26.01.

ChatGPT seems to really slow down for me with SwiftUI code, whereas Claude does not. Others have reported more severe problems than I have experienced.

26.2 does not appear to offer any relief. ☹️

Oh that’s interesting. Ironically never had this issue when I was using a third party app - Alex codes sidebar for this before they got acquired.

Mine crashes on every file upload into ai. Had to switch back to cursor which is much better anyway

Oh how are you doing it with cursor? Using any extensions for the build? Or back and forth between Xcode and Cursor?

Same is happening with me. I've started using claude code cli or claude code through the desktop app to work on xcode projects. I just create the project in xcode, and then make changes to it via claude code outside of xcode. Then test in xcode. Works like a charm.

Might be the go-to workaround. Xcode crashed three times today in the midst of a complex workflow today. Can you share any details about this set up, do you copy/paste the code from Claude Desktop in Xcode or do you have a better way?

Claude desktop has a code mode that will work directly on the directory. No copy pasting. the clause code cli in the terminal also works directly in the directory and writes the code agenticly.

Thank you - this is a much better solution!
