React Native - Apple Sign In

I followed the doc to add Sign in with Google, Facebook and Apple from here: https://docs.amplify.aws/lib/auth/social/q/platform/js

Google and Facebook work perfectly fine but I couldn’t make Apple work after a whole day debugging.

Here’s some screenshots of the flow:

Here’s my logs from the Hub

Alright. After another afternoon debugging this with the amazing help of @amhinson, I finally made it working. It basically was something like this: Here’s the steps I did (not sure which one helped):

• I added the Sign in with Apple capability in my project in Xcode (pretty sure that’s only needed if you use the iOS SDK, but doesn’t hurt)
• I deleted the user group created in User Pool > General settings > Users and groups > Groups > us-east-xxx_SignInWithApple
• I disabled the Apple IDP in Federation > Identity providers > Sign in with Apple
• I recreated that IDP (same sid, team id, key id, key file, and scopes email+name)
• Enabled it again in App integrations > App client settings
• Set up the attributes mapping again in Federation > Attribute mapping > Apple (email is unchecked by default)
• Removed the app in my https://appleid.apple.com settings under Security > APPS & WEBSITES Hope this helps anyone who’s seeing this invalid_client error

in my experience since apple is making mandatory using “sign in with apple” in your project like a mobile app if you use other socials like Facebook or google, nothings seems to solve the issue that amplify with cognito using federatedSignIn with apple sign in does not work at all! I have spent days testing everything and still not having any solution! Please amplify put a clear working sample of using federatedSignIn with signInwithApple because it seems it is not working and only Facebook and google socials works fine! thanks
