Hi everyone,
Since updating to Xcode 26, I’ve been running into an issue with the new ChatGPT integration inside Xcode.
Even though I have an active ChatGPT Plus subscription (GPT-4 or GPT-5) and I’m signed in to my OpenAI account, Xcode doesn’t seem to recognize my paid plan. After reaching the free usage limit, I get the following message:
“Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account or upgrade to ChatGPT Plus.”
The issue is that I am already logged in with my ChatGPT Plus account, and everything works fine on the ChatGPT web app — but inside Xcode, it keeps treating me as a free user.
Here’s what I’ve tried so far: • Signing out and back into ChatGPT from within Xcode • Restarting Xcode and macOS • Verifying that I’m logged in to ChatGPT in Safari • Updating both macOS and Xcode to the latest versions
None of these steps have resolved the issue. It seems like Xcode isn’t syncing properly with OpenAI authentication, and therefore it applies the free-tier limits even for paid accounts.
Has anyone else encountered this problem? Is there any way to force Xcode to reauthenticate with OpenAI or link it properly to a ChatGPT Plus account?
System setup: • Mac mini (Apple M2, 16 GB RAM) • macOS Tahoe 26.0.1 • Xcode Version 26.0.1 (17A400)
Here’s the error message I’m seeing:
