Expo Apple Sign-In Setup

My React Native app is built with the managed Expo workflow and is already live on iOS with Google Sign-In. Apple now requires “Sign in with Apple,” so I need someone who can drop in the new auth flow, match the look and feel of the existing Google button, and get a fresh build submitted to App Store Connect.

I have an active Apple Developer account, the project is in a private Git repo, and everything else is running smoothly in production. What I’m missing is:

• Adding “expo-apple-authentication” (or the current best-practice package)
• Configuring App ID, service IDs, and entitlements in the Apple Developer portal
• Integrating the native button so it mirrors the Google Sign-In UI already in the app
• Handling the credential response, token exchange, and graceful fallback for unsupported devices
• Producing a clean iOS build (EAS or classic Expo build is fine) and uploading it to TestFlight / App Store Connect for my final review

I can invite you to both GitHub and the Apple team right away. Once Apple’s automated checks pass and I see the button working in TestFlight, the job is done. If you have recent experience shipping an Expo Apple sign-in update, this should be a quick win for both of us.
