ChatGPT in Xcode 26 not recognizing Plus subscription

Fixing ChatGPT Plus Quota Issues in Xcode 26

With the release of Xcode 26.0 (17A324) on macOS 26 Tahoe, Apple introduced the built-in Coding Assistant powered by large language models. Developers can connect their personal ChatGPT accounts directly inside Xcode under Settings → Intelligence.

Some users, however, are seeing an error message inside Xcode:

“Over daily limit. Sign in with a paid ChatGPT account.”

This happens even when System Settings correctly shows the user is logged in with ChatGPT Plus.

Resolving the Issue

Here’s a guide to resolving the issue.

Confirm Requirements (at this time)

• macOS 26 Tahoe with Apple Intelligence enabled
• Xcode 26.0 (17A324) or later
• A valid ChatGPT Plus subscription linked to your OpenAI account

Step 1: Re-Link ChatGPT in macOS Go to System Settings → Apple Intelligence & Siri → ChatGPT. Sign out. Sign back in with the ChatGPT Plus account you want to use. Verify that your Plus status displays correctly here before opening Xcode.

Step 2: Connect ChatGPT Inside Xcode Open Xcode → Settings → Intelligence. Locate “ChatGPT in Xcode.” If it shows connected, sign out and sign back in from this panel. Ensure the panel now displays your account and not the Apple-provided free tier.

Step 3: Refresh Tokens Quit Xcode. In System Settings, toggle Apple Intelligence off, then back on. Re-enable ChatGPT, sign in again, and relaunch Xcode.

Step 4: Avoid the Free Tier Cap Apple includes a free daily quota for ChatGPT usage in Xcode. If Xcode is bound to this Apple-provided pool, you’ll hit a daily cap even with Plus. Switching Xcode to use your personal ChatGPT account removes the cap.

Step 5: Eliminate Account Conflicts If you have multiple ChatGPT accounts, log out of all browser sessions before re-authenticating. Ensure that Xcode links to the correct Plus subscription.

Step 6: Update macOS and Xcode Install the latest macOS 26 and Xcode 26 point releases. Apple has issued fixes related to account linking and quota checks since the initial release.

If the Error Persists

• Full Reset: Sign out of ChatGPT in both System Settings and Xcode, restart the Mac, then re-link in System Settings and again in Xcode.
• API Key Workaround: In Xcode → Settings → Intelligence, choose Add a Model Provider. Use https://api.openai.com/v1 as the endpoint. Add header Authorization: Bearer and select a model such as GPT-4.1. API usage is billed separately from Plus.
• Report to Apple: File a Feedback Assistant report under Developer Tools → Xcode → Intelligence. Include screenshots or recordings of the error message and your account status.
• Contact OpenAI Support: If the issue is on OpenAI’s side, submit a ticket at help.openai.com.

Key Takeaways

The “daily limit” banner in Xcode 26 usually means the editor is still tied to Apple’s free daily quota instead of your Plus subscription.

The fix is to re-authenticate in both macOS and Xcode until Xcode shows your ChatGPT Plus account explicitly. If problems continue, an API key connection provides an immediate workaround.

Some research I pulled together. Hope it helps. johncarmean 09/20/2025

Same error. Can't fix it

Same problem. I've tried everything suggested. I can't fix it either.

yep still can't use my plus account either...

I have started hitting this. Really annoying, it started with forcing me to start new conversations but now has the 24h limit even when signed in to ChatGPT in system settings and Xcode. I tried the steps above which made no difference.

Xcode Version 26.0 (17A324)

Came here to say I'm also having this issue.

Xcode Version 26.0.1 (17A400)

One more, same issues. Logged in with a plus account, still getting the "over daily limit".

Now if the maintainers would bump this issue to be fixed in xcode 26.0.2 or 26.1, it would be greatly appreciated.

Same problem here. Proposed fix doesn’t work.

Same problem here 😞 I have to use the Chatgpt app but don’t have access to to the full project context
