Location: Chandigarh, India

Budget: Recommended by industry experts

Time to start: As soon as possible

Project description:
"My React Native live-streaming app uses Firebase Auth with Apple Sign-In. Locally the login flow is flawless, but once the build is uploaded to TestFlight it throws a plain “network error” as soon as the Apple login button is pressed. Everything else in the build behaves, so I suspect a mismatch in Apple service IDs / certificates or the way Firebase handles tokens in the TestFlight environment. I have not been able to verify TestFlight-specific network settings yet, so that angle may also need a quick check.

I need someone who can jump in right now and deliver a fix within the next 2–3 hours. You’ll have access to the source repo, Firebase console, and my Apple Developer account so you can regenerate certificates, tweak entitlements, or adjust [login to view URL] settings as required.

Deliverables (today):
• A TestFlight build where Apple Sign-In succeeds end-to-end
• A concise summary of every change you made so I can replicate the setup for future builds

You should be fully comfortable with React Native, Firebase Auth, Apple Sign-In, Xcode, and the Apple Developer Portal. If you’re ready to tackle a high-priority hotfix, let’s get started immediately." (client-provided description)
