This issue is caught by the stricter xcode 10 new build system.

A temporary fix while react-native really fix the issue is to switch back to using the old build system

In Xcode, Select File -> Project/Workspace Setting. You will see a Build System option to select the Legacy Build System as shown below

Legacy Build System option

Clear your project and "Derived Data" Build and Run your project

BONUS Point: If you are using a CI/CD pipeline you can also add the xcodebuild argument -UseNewBuildSystem='NO' to the cli or via fastlane xcargs: "-UseNewBuildSystem='NO'"

Daniel's answer helped me to solve problem. Just note that if it's tvOS, then the same action of removing and adding should be done of RCTWebSocket-tvOS.a

This helped me:

Remove and add again libfishhook.a from Xcode and the path issue will resolve.

Manually copypasting libfishhook.a into the correct folder, as suggested here, worked for me:

For a solution, I copied the file from my ios/build/Build/Products/Debug-iphonesimulator/libfishhook.a and pasted it into ../node_modules/react-native/Libraries/WebSocket/ and got the build. I hope it helps.
