title: can't find ios framework headers in react native module library
body: <p>I've included an iOS framework in the xcode project for the React Native module library I'm creating. Everything compiles fine when I build the ios project in the RN library itself, but once I npm install the library into my main RN project, running <code>react-native link &lt;project-name&gt;</code>, and then build in xcode, the included framework headers are not found.</p>
  
  <p>I checked the normal build settings (Header, Framework, and Library search paths) and they all have $(inherited) listed. </p>
