rn-fetch-blob: 'React/RCTDefines.h' file not found

Ok, I managed to fix it (for me, at least). What you do is the following:

1. Go to Project navigator > Libraries > RNFetchBlob.xcodeproj
2. Click on Build Settings and then the first item under “Targets”
3. Scroll down to ‘Search Paths’
4. Double click to edit the ‘Header Search Paths’
5. Add the following entry (click ‘+’): ${SRCROOT}/../../../ios/Pods/Headers. Make sure to set it to recursive.
6. Clean (cmd + shift + K) and re-build (cmd + B)

Repeat for other libraries that complain about missing React/<whatever>.h files, perhaps with differing amounts of ../ before the ios/Pods/Headers/

@josectobar Where are you adding that workaround? If I replace the error line in the OP with that, I just get new errors ('React/RCTAssert.h' file not found).

Did anyone got this error while trying this solution?

I have the same issue. React-Native: 0.62.2 React: 16.11.0 rn-fetch-blob: 0.12.0

Recursive option was also set

After following the ${SRCROOT}/../../../ios/Pods/Headers I ran into another issue with duplicate symbols.

Anyone have any ideas how to fix this? 🤔 (Edit: fix is down below 👇🏾 )

❌  duplicate symbol '_OBJC_CLASS_$_RNFetchBlob' in
┌─ librn-fetch-blob.a(RNFetchBlob.o)
└─ libRNFetchBlob.a(RNFetchBlob-a70a61ec5fbdd003117a6dd9c81d14ef.o)

❌  duplicate symbol '_OBJC_METACLASS_$_RNFetchBlob' in
┌─ librn-fetch-blob.a(RNFetchBlob.o)
└─ libRNFetchBlob.a(RNFetchBlob-a70a61ec5fbdd003117a6dd9c81d14ef.o)

❌  ld: 73 duplicate symbols for architecture arm64

❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

...

Edit (fix found 🚀 ): Here’s the fix:

1. removing libRNFetchBlob.a from Your_Project_Name > General > Frameworks, Libraries, and Embedded Content (assuming you following the manual linked guide like I did)
2. adding the pod directly to my share extension in my Podfile:

target 'py_project-share-extension' do
  use_react_native!(
    :hermes_enabled => false,
    :flipper_configuration => flipper_config
  )

  pod 'rn-fetch-blob', :path => '../node_modules/rn-fetch-blob'
end

1. run pod install from the ios folder 🤞🏾

The issue seemed to be that because I was already linking the pods directly (see pic below) I didn’t need to manually add the libRNFetchBlob.a file. Here’s what my final frameworks section looked like:

Hi @judygab, I tried your solution and got the errors you mentioned above too. Did you solve it already? If so, can you please tell me how? Thanks in advance.
