Description
When integrating React Native into an iOS project, I encountered an error: 'react/bridging/CallbackWrapper.h' file not found.
After verifying, I found that setting install! "cocoapods", :generate_multiple_pod_projects => true causes the error, while setting it to false resolves the issue. Why does this happen? How can I resolve the error without changing generate_multiple_pod_projects?
Steps to reproduce
add install! "cocoapods", :generate_multiple_pod_projects => true in podfile
