Xcode 12 compatibility issue leading to build failure

[Gethyl]

Issue

Build fails while linking RNSVG.

As you see in the screenshot, RNSVG cannot find the required React modules because at Pod install, they weren't linked.

Fix

Update the dependency in podspec file to use React-Core instead of React.

Temporary work around

For now I have to manually link them before running and then the build succeeds. We build as frameworks, but the idea should be similar for other as well I guess.

Expected Results

Build shouldn't fail at linking of RNSVG.

Versions

React Native - 0.63.4
Xcode - 12.2

If any one still has this issue, I eventually automated this by writing a small shell script as shown:-

#!/bin/bash
#$node_module_path - node_module folder path
for podspec_file in $(find $node_module_path -name "*.podspec"); 
do 
# Change dependency 'React' to 'React-Core' to fix issue with React.Framework not added as dependency
  sed  -i '' "/s.dependency/  s/'React'/'React-Core'/"  "$podspec_file"
done

This will scan for all the podspec files and replace 'React' to 'React-Core' in the dependency

Haven't tried through our CI pipleline which is a linux box, but works fine on my local mac.
