ld: library not found for -lRCTBlob clang: error: linker command failed with exit code 1 (use -v to see invocation)
Getting the above error when building react-native project in Xcode11. I recently upgraded to react native 0.61.5 and everything works fine on android. No Idea why it is not working on iOS.
I'm really new to iOS and react-native. If you need any further information please ask.
回答1:
I have solved the issue by removing all react-native library linking from xCode by following these steps,
- Open
Project.xcworkspacefile in xCode - Go to project navigator tab
- Click on the project folder
- Then select the project name in the Targets section
- Open Build Phases tab
- Expand Link Binary With Libraries section
- Remove all binaries expect
libPods-Project.a
Then rebuild the project.
