[iOS] build fail when includesGeneratedCode is false

[LuongTruong]

I create a new react native library using the below cmd

npx create-react-native-library@0.49.0 my-codegen --reactNativeVersion 0.78.0

Step by step to reproduce:

1. I change the includesGeneratedCode to false
2. I run the pod install again
3. I run the app and there is an error at MyCodegen.h:
   line #import "generated/RNMyCodegenSpec/RNMyCodegenSpec.h"
   message 'generated/RNMyCodegenSpec/RNMyCodegenSpec.h' file not found

I check and see that the RNMyCodegenSpec.h now is in different folder. Therefore, I chang the import to:
#import "generated/build/generated/ios/RNMyCodegenSpec/RNMyCodegenSpec.h"

The error is gone, but when I build the MyCodegenExample, there are 2 errors:

1. 15 duplicate symbols
2. Linker command failed with exit code 1 (use -v to see invocation)

Please let me know if you have any idea to solve the issue. Many thanks!

Have you followed these steps? https://callstack.github.io/react-native-builder-bob/faq#how-to-opt-out-of-shipping-codegen-generated-code

Hello @satya164 , thank you for a very fast comment.

I tried it as soon as you give me the link but I still can't build the iOS project.

I am wondering, the only different is removing "codegen" from "react-native-builder-bob" -> "targets", which will ignore the "codegen" when we run script "prepare"

The thing is when we set includesGeneratedCode = false, the header file "RNMyCodegenSpec.h" can't be found with path

#import "generated/RNMyCodegenSpec/RNMyCodegenSpec.h"

but available in

#import "generated/build/generated/ios/RNMyCodegenSpec/RNMyCodegenSpec.h"

Hello @satya164 ,

After doing research for a few days, I finally found away to keep the codegenConfig -> outputDir stay the same. Therefore, no more issue appear.

Following, I also share how to config a library for Android in this link - Trouble Shoot section.

Thanks to the new version of create-react-native-library: 0.49.0
