Create new app with react-native-cli, update package.json to "react-native": "facebook/react-native" rerun npm i and get:

This is on Xcode 7 GM. I understand master isn’t meant to be as stable as a release or rc build, so not sure if a compile time error like this is within the norm.

as a temporary patch I’ve opened up node_modes/react-native/packager/react-packager/src/Server/index.js and patched this

  platform: {
    type: 'string',
    required: true,
  }

to this

  platform: {
    type: 'string',
    default: 'ios',
  }

now it compiles and works fine for me

A bit of debugging traced back to this line: https://github.com/facebook/react-native/blob/master/packager/react-packager/src/Server/index.js#L410

  _getOptionsFromUrl(reqUrl) {
   // ...
    return {
      // ...
      platform: urlObj.query.platform,
    };
  }

I’m assuming this is in flux to support android. For others that come across this issue, simply adding a platform param to the querystring in AppDelegate.m will get you going again:

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios"];

Although I haven’t tried using react-native bundle yet, which also may need some help.
