title: Apple Mach O Link Key failed when compiling GooglsMaps.Framework
body: <p>I have tried to add all <code>GoogleMaps.Framework</code> and <code>GoogleMaps.bundle</code> at the framework
  When it comes to the execution, it causes the following error </p>
  
  <p>I have no clue on what happens exactly. Would you please tell me the proper way to add <code>Google MAP SDK frameworks</code> instead ? </p>
  
  <p>I have even added the framework libc++.dylib.</p>
  
  <p>The error message</p>
