未定义符号：Flutter iOS 上的 __swift_FORCE_LOAD_

我正在Mac M3上设置一个flutter项目。我收到以下错误

我也遇到这个问题了。我发现这与Facebook的一些库的升级有关。这是错误日志：

CopyUndefined symbols for architecture x86_64:
  "__swift_FORCE_LOAD_$_swift_Builtin_float", referenced from:
      __swift_FORCE_LOAD_$_swift_Builtin_float_$_FBAudienceNetworkSwift in FBAudienceNetwork[x86_64][2](FBAudienceNetworkSwift.o)
      __swift_FORCE_LOAD_$_swift_Builtin_float_$_FBAdFilterEngine in FBAudienceNetwork[x86_64][3](FBAdFilterEngine.o)
      __swift_FORCE_LOAD_$_swift_Builtin_float_$_FBAdMAISKOverlayManager in FBAudienceNetwork[x86_64][4](FBAdMAISKOverlayManager.o)
      __swift_FORCE_LOAD_$_swift_Builtin_float_$_FBAudienceNetwork in FBAudienceNetwork[x86_64][406](FBAudienceNetwork.o)

我已更新 Podfile.lock 以使用这些版本的 Facebook 库：

- FBAEMKit (17.0.2):
    - FBSDKCoreKit_Basics (= 17.0.2)
- FBAudienceNetwork (6.15.1)
- FBSDKCoreKit (17.0.2):
    - FBAEMKit (= 17.0.2)
    - FBSDKCoreKit_Basics (= 17.0.2)
- FBSDKCoreKit_Basics (17.0.2)
