Put following code before the } at the end of FBUnityInterface.mm file located in FacebookSDK/SDK/Editor/iOS

  void IOSFBEnableProfileUpdatesOnAccessTokenChange(bool enable)
  {
    [[FBUnityInterface sharedInstance] IOSFBEnableProfileUpdatesOnAccessTokenChange:enable];
  }

me too.

For now, you can comment the line below in the "Facebook.Unity.IOS.cpp" file

reinterpret_cast(IOSFBEnableProfileUpdatesOnAccessTokenChange)(static_cast<int32_t>(___enable0));

to make it build successfully, but it's NOT the best and final solution.
it's a definitely temporary solution, someone has a better answer?

I'm seeing the same error:

Undefined symbols for architecture arm64: "_IOSFBEnableProfileUpdatesOnAccessTokenChange", referenced from: _IOSWrapper_EnableProfileUpdatesOnAccessTokenChange_m7ADB5E4C2DE8D7EB448729C43F65D1FFECB5F0CC in Facebook.Unity.IOS.o _IOSWrapper_IOSFBEnableProfileUpdatesOnAccessTokenChange_m7E35B38EDDDF18DE2B0B960DA8269D277C8FBCAB in Facebook.Unity.IOS.o (maybe you meant: _IOSWrapper_IOSFBEnableProfileUpdatesOnAccessTokenChange_m7E35B38EDDDF18DE2B0B960DA8269D277C8FBCAB) ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

My setup:

Unity Editor Version: 2020.1.11
Unity SDK Version: 9.1.0
Installation Platform & Verison: [iOS] version 14.4.2
XCode: 12.4

I haven't tried the above suggestions, yet.

I tried this and I was able to build!

@firatagdas's solution works for me too.

It also fails using Unity 2019.4.31

ivangice on 15 Apr 2021

It also fails using Unity 2020.1.16f1

kikasik on 15 Apr 2021

looks to fail on any and all Unity versions, @firatagdas solution works perfect got builds out using that to compile with no issues so far. Does seem pretty impressive they released a sdk that does not even compile on a platform.

cmcpasserby on 15 Apr 2021

Sorry Facebook but you are amateurs. Are you even trying to build live projects with you SDK? And the bug report is here for 7 days... What about hotfix?

@firatagdas, His solution worked for me as well.

mansoor090 on 20 Apr 2021

Any news about this issue? I manage to fix with @zhengwu119 suggestion, but I need a fix to be able to build with cloud build please.

Thanks. It's helped me.

@firatagdas 's solution worked for me with 2019.4.24, thank you @firatagdas 💯

another one for @firatagdas here. Facebook SDK 9.1.0 with Unity 2019.4.11f1. Good stuff my dude

lexi89 on 26 Apr 2021

Thanks to @firatagdas. Proposed solution (see below) works for my use case. The FB team can take care of this bug. Looks the solution is here in the comments, at least for some use cases. The fix seems to be pretty simple -> should be easy to release bug fix.

void IOSFBEnableProfileUpdatesOnAccessTokenChange(bool enable)
  {
    [[FBUnityInterface sharedInstance] IOSFBEnableProfileUpdatesOnAccessTokenChange:enable];
  }

This means that they do not even try to build for iOS really - but yeah, @firatagdas fix worked for me as well. Not sure if I should feel safe enough to actually put this on our next release though...
