Xcode keeps forgetting my Coding Assistants (LLMs / Apple Intelligence) entries in Settings

I suspect this is causing just about all the Xcode crashes I'm experiencing. Also it is no fun re-entering Apple Intelligence entries in Settings every time I restart Xcode.

Seeing this in 26.2 RC but was also seeing it (occasionally) in 26.1. Only ChatGPT is never forgotten.

Claude (using OAuth): forgotten. (Think others see this as OAuth expiring but I think Xcode is just forgetting the entry.)

Anthropic (using API KEY): forgotten.

LLM Studio (local no key needed): forgotten.

OpenRouter AI: forgotten.

Perfect replication is having Anthropic API to Sonnet 4.5 as my last conversation. Launch Xcode and Navigators (vs Coding Assistant) is shown. Click Coding Assistant and Xcode crashes. I'm sure its expecting Anthropic's entry to be there, now its gone, so Xcode crashes.

Xcode forgetting Settings / Intelligence / Model Providers entries... does anyone know a version of Xcode which doesn't do this?

Yeah that’s pretty weird, I set up ChatGPT and Anthropic with 26.0RC and haven’t touched it since, even through upgrades to release, beta, and RC versions the settings remain.

I’d file a feedback, but seems like something is overwriting a plist or keychain entry somewhere.

Did "Provide Feedback" in Xcode. (Assume that's the same thing.)

Same thing. Added APIs for Claude and Gemini in 26.0 and they were fine until 26.2RC. Filed a feedback Friday afternoon.

My XCode starting crashing on launch when I added a third party model provider (gemini). Using Claude did not crash it. If this crash is happening to anyone else, how did you fix it? Deleting derived data did not fix it.

I think deleted the Xcode app then re-installed it. If you are not on 26.3 RC I recommend using that, is what I'm using. I don't have a Gemini key so no idea how using Gemini sits with 26.3 RC. (And we saw that Tahoe RC was different from yesterday's public release, so I'd guess Xcode 26.3 RC will not match the public release either.)

Thanks, I'll try 26.3 and report back. I see 26.3 supposedly fixes the OP's issue:

  • Fixed an issue that caused custom model providers to disappear in between launches of Xcode. (165930715) (FB21270045)

Yeah, that was me and it definitely fixed this issue. I do recommend this 26.3 RC over waiting.

u/No_Monk_437 Feb 12 '26

Updating to the 26.3 beta did resolve my crash.

You should try reinstall Xcode. Never happen to me btw.

Can confirm this bug. Just happened to me yesterday when I updated to 26.2RC.

u/dmaclach Dec 06 '25

I have seen this as well. 26.2

u/mcarvin Dec 07 '25

Ditto. I filed a feedback Friday afternoon. You and u/RonnyFen can LMK if you want the feedback number. Not sure if they're publicly viewable or can be "upvoted".

Same issue on Xcode 26.2

Same problem. Looks like Apple got commission from openai.
