(Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.)

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will
likely receive a faster response on your issue.

Relevant Code:

Engine : Unity 2020.1.10f1
Using Firebase and Facebook SDK Unity SDK 9.0.0
Build in iOS and Xcode 12.4

I have two error during build in Xcode after add Facebook SDK

'FBSDKCoreKit/FBSDKCoreKit.h' file not found

This error just happened at .xcodeproj
I don’t know why but It didn’t happened if I builded it at .xcworkspace
But even at .xcworkspace , I still faced the error 2

Undefined symbol: OBJC_CLASS$_GKLocalPlayer

I already tried this solution :

adding GameKit.framework to your xcode prject from
Targets -> UnityFramework -> General -> Frameworks and Libraries
-> click + button and find GameKit.framework -> rebuild.

But it didn’t work for me.
Also try to add
libFirebaseCppAuth.a in Compile Sources . But it still failed to build .
Please help me if you know how to solve it.

Hi @sparrow06078,

You mentioned you've tried solution I guess reference from this comment, which I also see in a following one it mentioned that works with a clean first and then build. Could you try again to see if that can also help you?

I tried this but didnt work.

Targets -> UnityFramework -> General -> Frameworks and Libraries
-> click + button and find GameKit.framework -> rebuild.

'FBSDKCoreKit/FBSDKCoreKit.h' file not found sounds like an error with the Facebook SDK you're using. Have you confirmed that using the Facebook SDK works when Firebase is not included? Or the opposite: that Firebase works when Facebook is not included?

GameKit.framework also shouldn't affect Firebase SDKs as far as I know.

Can you try starting from the Unity Quickstart app and see if you can get that working, then add in libraries until it breaks to see what specifically is breaking your build?
