title: Pod install installs deprecated react and creates a build error 'React/RCTBridge.h' not found
body: <p>I recently added some pods and ran pod install to a previously working project and now I get a warning that <code>React has been deprecated</code> and seems to have problems linking to React with a build error `React/RCTBridge.h' file not found.  This type of issue seems to happen with several different libraries I try to add via pod install.</p>

  <p>Is there a correct way I should have React configured in my Xcode or pod file that I am missing?</p>
