i don't know why it build fails.
but after i change the version to
"react": "15.3.2",
"react-native": "0.37.0",
the Example build succeeded

When receiving this error, the following works for me:

1. Open the project via XCode

2. Start it and you should get a RCTWebsocket error

3. Doubleclick the RCTWebSocket and remove the value (-werror - wall) within other warning flags
   ( See solution by TimBroddin @ https://github.com/facebook/react-native/issues/8584)

I think this error occurs because of the way react natives use of "use strict".
