This issue is caught by the stricter xcode 10 new build system.
这个问题被更严格的xcode 10 新构建系统捕获。
A temporary fix while react-native really fix the issue is to switch back to using the old build system
一个临时修复，而 react-native 真正解决这个问题是切换回使用旧的构建系统
In Xcode, Select File-> Project/Workspace Setting. You will see a Build System option to select the Legacy Build Systemas shown below
在Xcode 中，选择File-> Project/Workspace Setting。您将看到一个 Build System 选项来选择Legacy Build System，如下所示

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'"
加分点：如果您使用 CI/CD 管道，您还可以将 xcodebuild 参数添加-UseNewBuildSystem='NO'到 cli 或通过 fastlanexcargs: "-UseNewBuildSystem='NO'"

Manually copypasting libfishhook.a into the correct folder, as suggested here, worked for me:
按照此处的建议将 libfishhook.a 手动复制粘贴到正确的文件夹中，这对我有用：
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.

对于解决方案，我从我的 ios/build/Build/Products/Debug-iphonesimulator/libfishhook.a 复制了文件并将其粘贴到 ../node_modules/react-native/Libraries/WebSocket/ 并获得了构建。我希望它有帮助。

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
丹尼尔的回答帮助我解决了问题。请注意，如果是tvOS，那么RCTWebSocket-tvOS.a的删除和添加操作应该相同
