【问题描述】：
我使用 react native 0.65.1 和 Xcode 10 来创建一个 react native 应用程序。
我已将 ios/project.xcodeproj/project.pbxproj 和 ios/Pods/Pods.xcodeproj/project.pbxproj 中的 objectVersion 从 54 更改为 51，因此我可以在 Xcode 10 中打开 xcworkspace 文件。除此之外，我很漂亮遵循 react native 网站上的说明并没有改变任何东西。
运行时
npx react-native run-ios
在终端中，我在“/node_modules/react-native/React/Views/RCTDatePickerManager.m”文件中主要（但不是全部）收到以下错误：
