Error: Sign up not completed. Apple Sign-In (iOS) not working despite correct configuration in iOS

[lesthoward]

Hi team,

I’m currently facing a persistent issue when trying to implement Sign in with Apple on iOS using the react-native-apple-authentication package. Despite having all required configurations in place, the sign-in flow fails with the error: Sign Up Not Confirmed.

❗️Problem

After tapping the Apple Sign-In button, the system prompt appears, but I consistently receive the error: Sign Up Not Confirmed. This occurs even though I’ve confirmed multiple times that my Apple Developer settings and Expo app are properly configured.

🔧 Configuration details
• ✅ Apple Developer Account
• Certificate includes Sign in with Apple
• Provisioning Profile includes Sign in with Apple
• Apple Sign-In capability is enabled in Xcode
• ✅ Project setup
• Using Expo SDK 53
• usesAppleSignIn: true is set in app.config.js
• Using the expo-apple-authentication plugin
• Tried with both simulator and physical devices
• All packages are up to date (fresh install this week)
• ✅ Other attempts
• Tried with two different Apple IDs: a personal account and a company account
• Created a new Apple Developer app/project to discard account-level issues
• Generated a new provisioning profile with Sign in with Apple enabled
• Built manually in Xcode selecting the correct profile — build succeeds with no certificate issues

🔍 Observations
• It feels like Apple is not completing the sign-in process, even with correct setup.

📦 Environment
• Expo SDK 53 and React Native .0,79.3
• expo-apple-authentication
• macOS with latest Xcode
• Real and simulator tested

Facing same issue with 1. expo-apple-authentication package as well. Well it works perfectly in expo go.

That sucks!, it does even work well for me in Expo GO. I will skip Apple sign in for now to continue making progress on the app I am working on till I get a solutions. Please let me know once you find a solution

I suspect the issue is on apple side. Whenever I have an update, I will share.

I'm facing the same issue. This is an urgent issue for our app as Apple is rejecting the public release of our app because we have Sign In with Google working, but were holding off on Sign In with Apple because it doesn't work.

I have raised an Apple Developer Support issue as well.

Is this a recent arising issue or should we needs to configure anything on this ?

will do - also submitted a support request to apple. my feeling is that it's on their side. exact same code is working in another app - maybe other people can clarify, but it seems like it's related to the first login attempt - creating an account, not logging in.

as of now, not resolved.

Same here with react native CLI since 2 day continuous tried to make it work but it didn’t. I tried to change bundle id , created new key id , everything from scratch nothing happened. Tried console level debugging found nothing on error 1000.checked every where researched everything. 🥲 still no help . Please 🙏 if anyone from apple or react team . Lets us know how to debug pin point because its only showing error 1000 and some text . Not showing what actual case like bundle mismatch, permissions. Please look into that direction

I have the same issue. Very mysterious, and I hope it can be fixed before it's launch time.

Environment Details:

• React Native: 0.78.0
• Xcode: 16.2
• Device: iPhone (Real device)
• Library: @invertase/react-native-apple-authentication
• Capability: "Sign In with Apple" is enabled in Xcode
• Bundle ID matches App ID in Apple Developer portal
• Tested with clean build and fresh install

Despite these, I still get the 1000 error on calling appleAuth.performRequest.

Is there anything else I might be missing or any recent changes in iOS or this package that could be causing this?

Appreciate any insights or suggestions 🙏

Thanks!
