Xcode – Getting "ld: symbol(s) not found for architecture x86_64 clang" on one of nearly identicals machines

I’ve been on this for two days, searched every corner of the internet and couldn’t find any solutions.

Currently, when I try to build React-Native Xcode project on M1 Max, I get ld: symbol(s) not found for architecture x86_64 clang for a lot of symbols. While on regular M1, the build goes through.

I can’t seem to find any differences that would be even remotely related with the clang error.

Also asked few colleagues to run the project, got few with same error (M1 Pro and M1 Max) and one with nearly identical setup in every way and the build went through on his machine (M1 Pro MBP, same macOS (thought that Monterey and Big Sur could be different somewhere, but it seems not), ruby, node, etc)

I’ve also tried looking for any issues with search paths and project setup, but it looks fine (also it builds fine on other machines). That means it’s probably 100% setup problem. I should also mention, that other projects I’ve tried to build are working brilliantly.

Any directions which ways should I look into finding what’s so different between the machines?

Any comments would be really helpful, totally lost right now. Thanks.

    This works for me.

    You can exclude arm64 for simulator architecture both from your main Project and the Pod project.

    The only thing that worked to me was replace all the part from "post_install" on Podfile to the code below.

    use_flipper!()

post_install do |installer|
  react_native_post_install(installer)
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
  end
end

    After that. Run the following commands in terminal on iOS folder.

    pod deintegrate && pod install

    Now clean build cache on Xcode and run the project.

    Shortcut: CMD + SHIFT + K
