I am native iOS app developer but i also want to be aware of latest and trending technology so i choose to get my hands on react native.我是本地 iOS 应用程序开发人员,但我也想了解最新和趋势技术,所以我选择动手进行 React Native。 Now, i am getting this error when trying to run my react native created app on iOS.
现在,我在尝试在 iOS 上运行我的 React Native 创建的应用程序时遇到此错误。 I enter the command react-native run-ios and simulator started and after that app opened but in starting it showed this screen.
我输入命令 react-native run-ios 和模拟器启动,并在该应用程序打开后但在启动时显示此屏幕。

for now after react-native init, since a lot of new changes are coming out, this fix worked for me (I got it from reading other issues):
with npm:
npm install --save-dev @babel/core
npm install --save-dev @babel/runtime
or with yarn:
yarn add --dev @babel/core
yarn add --dev @babel/runtime
if on ios you get _this._registerEvents is not a function, after a successful build
do
npm run start --reset-cache
or
react-native start --reset-cache
For me i got reason for issues that for now since a lot of new changes are coming out like Xcode 10 itself is new and react native is not yet merged with that, this fix worked for me:对我来说,我现在有一些问题的原因,因为很多新的变化正在出现,比如 Xcode 10 本身是新的,而 react native 尚未与它合并,这个修复对我有用:
with npm:使用 npm:
npm install --save @babel/runtime npm install --save @babel/runtime
or with yarn:或用纱线:
yarn add @babel/runtime纱线添加@babel/runtime
