Apple Sign-In

Enable provider in Firebase

1. In Firebase Console → Authentication → Sign-in method.
2. Click Apple and toggle Enable. No extra OAuth config is needed for the default flow.

Configure capability in Xcode

1. Open ios/Runner.xcworkspace in Xcode.
2. Select Runner in the project navigator → Signing & Capabilities.
3. Click + Capability and add Sign in with Apple.
4. Ensure your Team and Bundle Identifier (com.yourdomain.prohandy) are selected and the provisioning profile is valid.

After enabling

• Rebuild for iOS; test on a real device (Simulator Apple Sign-In requires a real Apple ID).
• If the button does not appear, verify the capability was added to ios/Runner/Runner.entitlements (Xcode does this automatically).
