Be sure that RN codegen properly ran.

Run https://www.npmjs.com/package/react-native-clean-project if required.

Hello @yashdiq

Did you manage to solve the problem?

I'm facing the same issue but can't see anything wrong during RN codegen. When I comment out Bootsplash, everything builds correctly.

[yashdiq]

not yet @nagykrisztianendre, it's been days and what @zoontek suggested is not working.

[nagykrisztianendre]

Hello @yashdiq

I was able to solve the problem on my end. The root cause was indeed related to the codegen, specifically because the files were not correctly compiled. To solve the issue, I changed the setting in Xcode under Build Settings -> Apple Clang - Language -> Compile Sources As to 'Objective-C++' instead of 'According to File Type,' and everything built successfully after that.

I hope this solution works for you as well.

Hi @nagykrisztianendre I wanna try your workaround above but I can't see this option: Build Settings -> Apple Clang - Language -> Compile Sources As to 'Objective-C++'. Can you give me the screenshot of your XCode?

[nagykrisztianendre]

Yes. @yashdiq Here it is:

[yashdiq]

Thanks bro @nagykrisztianendre found it.

[yashdiq]

Still the same 😂

[nagykrisztianendre]

Have you tried running pod install before rebuilding the project?
