clang: error: no such file or directory: '/Users/user/Library/Developer/Xcode/DerivedData/client-xxx/Build/Products/Debug-iphonesimulator/libRNIap.a' Command Ld failed with a nonzero exit code

I haven’t run my project’s code since April (though it’s live on the app store and works) and am trying to get it in a development state again. When building I am running into:

clang: error: no such file or directory: '/Users/user/Library/Developer/Xcode/DerivedData/client-xxx/Build/Products/Debug-iphonesimulator/libRNIap.a' Command Ld failed with a nonzero exit code

    "react": "16.8.3",
    "react-native": "https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz",
    "react-native-iap": "2.3.26",

Any advice would be appreciated.

@booboothefool This is more like a react-native problem itself. Try to remove ios/build and run build again. This also looks like an old problem which happened in previous react-native.

Maybe this reply from me might help too.

@hyochan I think I was able to get past the error! 👍

Seems like my issues are related to Xcode 11 -> Xcode 12?

I am not why this helped, but I did:

• Workspace Settings > Build System: Legacy Build System (Deprecated), Derived Data: Workspace-relative Location

Then I started getting:

No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=arm64e armv7s arm64 arm7)

So I went to Build Settings > Build Active Architectures Only: Debug: No

After that the file is no longer red:

Got past RNIap error and now just getting Expo/Amplitude and Firebase error. 😅

ld: library not found for -lAmplitude-iOS
ld: library not found for -lRNFirebase

I should probably just use my holiday vacation to download new React Native + Expo and copy all project files over with updated dependencies before it becomes unfixable, haha. 😂

Thanks!
