title: Google Endpoints in iOS with Google Sign-in
body: <p>I am trying to setup the <code>Client API</code> files for Google Endpoints in iOS, I generated all the files fine but now when I try to import them (foo.h and foo_Sources.m) into my project I keep getting build errors saying </p>
  
  <blockquote>
    <p>GTLDefines.h file not found</p>
  </blockquote>
  
  <pre><code>#if GTL_BUILT_AS_FRAMEWORK
    #import "GTL/GTLDefines.h"
  #else
    #import "GTLDefines.h" //error on this line of the files
  #endif
  </code></pre>
  
  <p>Since I have already integrated Google Sign-in (with GoogleOpenSource.framework) I am not suppose to manually bring in files from the <code>GTLSource project</code>. I did it just to see what would happen and I get lots of errors saying <code>multiple interfaces/properties defined</code> in all the files.</p>
  
  <p>So how am I suppose to fix the error of GTLDefines.h missing?</p>
  
  <p>these are the <a href="https://cloud.google.com/appengine/docs/java/endpoints/consume_ios" rel="nofollow">instructions</a> I am going off of to do this. The docs still references the now deprecated Google+ login api, are the instructions still the same from the new google sign-in api?</p>
