title: Xcode 7 simulator error "duplicate symbols for architecture x86_64"
body: <p>My development environment with <code>Xcode 7.2.1</code>, <code>CocoaPods 1.0.0</code> and <code>GoogleMaps 1.13.2</code></p>
  
  <p>I can build code successful to generate a XXX.ipa file and install in my iPhone 6 Plus to work correctly.</p>
  
  <p>But when I run Xcode simulator by item "iPhone 6" or "iPhone 6 Plus" always get the information as below</p>
  
  <blockquote>
    <p>"xxxx duplicate symbols for architecture x86_64" "linker command
    failed with exit code 1 (use -v to see invocation)"</p>
  </blockquote>
  
  <p>I use the following solutions still can't fix it</p>
  
  <ol>
  <li><p>Build Options -> Enable Bitcode -> set "No"</p></li>
  <li><p>Remove -ObjC from Other Linker Flags</p></li>
  <li><p>project Targer -> Build phases -> compile sources, ckeck no duplicate files</p></li>
  <li><p>Make sure I haven't #imported a .m file</p></li>
  </ol>
  
  <p>I am wondering if there are any other method to solve this, help would be appreciated thanks.</p>
