React Native iOS App crashes

Question

I followed the "Getting Started" to build my first React Native App.

This is what I do:

npm install -g yarn react-native-cli

react-native init AwesomeProject
cd AwesomeProject
react-native run-ios

However, the app crashed after building successfully.

Then I open Xcode to run the app, but the app crashed again.

Here is the information:

Answer 1

The reason is that Shadowsocks is running in the global mode. The problem solved after I turned it off.
