    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

    1.
    '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

    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.
