构建依赖于GoogleAnalytics-iOS-SDK的Cocoapod验证失败

Question

Thanks for you help in advance,

I am see linker errors when creating a private cocoapod with a dependancy on GoogleAnalytics-iOS-SDK.

The relevant section of the podspec is:

s.dependency 'GoogleAnalytics-iOS-SDK', '3.10'

Projects which include my pod build and run, just the linter fails. Meaning I can't push the pod to my repo.

pod lib lint --verbose
Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_GAI", referenced from:
      objc-class-ref in Test.o
Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_GAI", referenced from:
      objc-class-ref in Test.o

What is causing this linker error? How do I work around it?

I've successfully added this dependency by adding the platform limit with this instruction in the podspec of your private library to limit to iOS devices only :

Pod::Spec.new do |m|
    ...
    m.platform = :ios, "7.0"
