Description

Good day, I am trying to upgrade a project to RN 0.62.2 from 0.61. On android it is working fine, however on iOS I am getting this error when running react-native run-ios

Undefined symbols for architecture x86_64:
  "_swift_getFunctionReplacement", referenced from:
      _swift_getFunctionReplacement50 in libswiftCompatibilityDynamicReplacements.a(DynamicReplaceable.cpp.o)
     (maybe you meant: _swift_getFunctionReplacement50)
  "_swift_getOrigOfReplaceable", referenced from:
      _swift_getOrigOfReplaceable50 in libswiftCompatibilityDynamicReplacements.a(DynamicReplaceable.cpp.o)
     (maybe you meant: _swift_getOrigOfReplaceable50)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I followed all instructions detailed here #13 and When I build the app from xcode interface, it runs with no errors. However, when trying to run it with react-native run-ios it raises the error. Do you have any idea why is it happening?

Thank you

I tried this solution https://github.com/react-native-community/upgrade-support/issues/25#issue-591311756 But it did not work. any idea?

I removed all flipper references from ios/Podfile and from ios/<project-name>/AppDelegate.m to make it work, but I will not be able to use Flipper in my project...

I have exactly the same issue. Finally resolved with this: https://github.com/react-native-community/upgrade-support/issues/25#issuecomment-658066246

Got past this issue with https://blog.cpming.top/p/undefined-symbol-swift-getfunctionreplacement @0.63.2

In Xcode, select PROJECT-> Build Settings-> LInking-> Dead Code stripping -> YES

[Brenw10]

I solved following #25 (comment) per @JeremyBradshaw7's comments. I've placed Yes for Dead Code Stripping, however it doesn't work in the first time, because I forgot to set this option for All the Targets as well and NOT ONLY the project.

I have the same error, but Build Settings-> LInking-> Dead Code stripping -> YES is already to YES, in project and all targets, any idea how to fix?

upgrading xcode worked for me :)

I am also getting the same issue, yet I have enabled dead code stripping. This is while previewing the watch os app,
