duplicate symbols for architecture x86_64 While adding pods from CocoaPods

问题

I am trying to use Google Analytics into my App.

But immediately after adding it via CocoaPod i am getting this Error:

Previously I have GoogleMaps and GCM in my pod.

Now My Pod is look like this:

platform :ios, '8.0'

pod 'Google/Analytics'
pod 'Google/CloudMessaging'
pod 'GoogleMaps'

How Can I resolve this Error:

*EDIT

This solve my problem:

If I run my existing project X-Code 7 then I am not getting the Error.

But I want it to run in Xcode 6.4 so I added older version of GA and that works fine with X-Code 6.4.

I have added manually the older sdk but if any one wants to add it Via Cocoa-Pod then Here is the way of doing it:

  pod 'Google/Analytics'
  pod 'GoogleAnalytics', '3.13.0'

回答1:

Please remove "Other linker flag" which is set in build setting. If it is set to -ObjC then please remove it and try to build again.

hope this works

This error often happens is accidentally importing the .m file instead of the .h
