ummmm....i downgraded RN version in library from 0.78 to 0.75.3 and re-run codegen, now it's finally working, but the question is - is it the solution?

[Luxlorys]

also in tsconfig.json file "moduleResolution": "Bundler" should be "moduleResolution": "bundler" though or you will get this error when downloading published library

Could not find a declaration file for module '@gromozeqa/react-native-apple-health-kit'. '/Users/andrei/dev/qwerty/node_modules/@gromozeqa/react-native-apple-health-kit/lib/commonjs/index.js' implicitly has an 'any' type.
  There are types at '/Users/andrei/dev/qwerty/node_modules/@gromozeqa/react-native-apple-health-kit/lib/typescript/module/src/index.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.

I had the same issue. In the podspec file: https://github.com/Luxlorys/react-native-apple-health-kit/blob/master/ReactNativeAppleHealthKit.podspec I had to wrap the s.private_header_files = "ios/**/*.h" command in an if statement to check if the new architecture was enabled or not. Try something like:

if ENV['RCT_NEW_ARCH_ENABLED'] == '1' then
    s.source_files = "ios/**/*.{h,m,mm,cpp,swift}"
    s.private_header_files = "ios/**/*.h"
  else
    s.source_files = "ios/**/*.{h,m,mm,cpp,swift}"
    s.exclude_files = "ios/**/*"
  end

Hey I think I will need more details. The following setup worked for me:

1. Created a new library (turbo module, same as yours)
2. Used yalc to publish it locally
3. Created a new app with npx @react-native-community/cli@latest init (The React Native version is 0.78.1
4. Used yalc to fetch the locally published lib
5. Installed pods and built the app

Everything worked fine. Can you setup a reproducible example of the app which you installed your library to? What React Native version does the app use? Is the new architecture enabled there?

3. Created a new app with npx @react-native-community/cli@latest init (The React Native version is 0.78.1

that's the problem, i tried to install the library to project with 0.75.3 RN (new arch enabled ofc)

Check repo here
And here is my library

For >0.76.0 RN your library will work fine, but my project uses 0.75.3, so i downgraded library RN to 0.75.3 and Spec file was totally different

To check it download my library with version 0.1.5, install pods and got to lib/ios/generated/RNAppleHealthKitSpec and open header file, you will see this block which causes an error for RN 0.75.3
`@interface NativeAppleHealthKitSpecBase : NSObject {
@Protected
facebook::react::EventEmitterCallback _eventEmitterCallback;
}

• (void)setEventEmitterCallback:(EventEmitterCallbackWrapper *)eventEmitterCallbackWrapper;`

But if you install my library with version 0.5.0, install pods and got to lib/ios/generated/RNAppleHealthKitSpec to you will see completely different spec file which no longer causes errors for older RN and still works for 0.76.0+

Hey @Luxlorys can you check if you still have issues after disabling includeGeneratedCode? https://callstack.github.io/react-native-builder-bob/faq#how-to-opt-out-of-shipping-codegen-generated-code

May also need to bump react-native-builder-bob to the latest version.
