  <p>After typing out the import I don't see any errors or warnings. I can use the library with no problems. The library itself has warnings but those are related to Xcode 7.3 changes to swift. I have never noticed this before. </p>
  
  <p>Sometimes Xcode says my Pod project does not have recommended settings, but this still happens after applying the recommended settings.</p>
