title: Xcode 5.1 ld: library not found for -lGoogleAnalyticsServices
body: <p>Today I updated my Xcode to Xcode 5.1, and now every time I try to compile my code and test it on the simulator I got several errors about architecture 86_64 and Google Analytics Services Library.
  This is what I got:</p>
