ios - Xcode10 无法构建和运行 React Native

Question

新的react native项目可以react-native run-ios在设备上运行但不能在xcode 10上运行。

当我构建项目时出现错误。

我需要在 ios 中添加一些 native 模块，但现在我在 xcode10 中构建项目时遇到了问题。

据我所知，ios 项目使用 cocoapods 然后我尝试删除 podfile.lock 并再次运行 pod install 但它没有工作。

我也尝试删除 node_modules 文件夹并再次运行 yarn install 但仍然出现问题。

我希望构建它并且可以从 xcode 运行。现在只能通过命令react-native run-ios

运行

确保您已打开 "projName.workspace"，然后选择您的项目转到 "General"选项卡 -> "prjtNameTests" 然后选择主机应用程序 "你的项目”
