Google Analytics doesn't work on new iOS proje

Question

I have created a new iOS project and added Google Analytics support following by official instructions.

I've added to Frameworks:

libGoogleAnalyticsServices.a
AdSupport.framework
CoreData.framework
SystemConfiguration.framework
libz.dylib

But it doesn't work with the errors:

ld: warning: directory not found for option '-L/Users/.../Sources/GoogleAnalytics'
Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_NSManagedObjectModel", referenced from:
      objc-class-ref in libGoogleAnalyticsServices.a(GAICoreDataUtil.o)

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

How can I fix it? And does it support arm64?

Answer 1

You should add the libsqlite3.0.dylibfile to your frameworks.

To do this, under the projects target, on the general tab, you will find "Linked Frameworks and Libraries", just select the '+' button, and add the framework from there

Answer 2

From Google Analytics developer page

The Google Analytics SDK uses the CoreData and SystemConfiguration frameworks, so you will need to add the following to your application target's linked libraries:

• libGoogleAnalyticsServices.a
• AdSupport.framework
• CoreData.framework
• SystemConfiguration.framework
• libz.dylib

Looks like you are missing out CoreData.framework.

---

Running the lipo -info command on the GA library.

xcrun -sdk iphoneos lipo -info libGoogleAnalyticsServices.a

Gives result,

Architectures in the fat file: libGoogleAnalyticsServices.a are: armv7 armv7s i386 x86_64 arm64 

So it does support arm64.

Hope that helps!

Answer 3

Thanks for all! The following steps helped me:

1. Remove CoreData.framework.
2. Add again CoreData.framework.

arm64 is now supported. Thanks to Amar.

Now I should fix the last warning:

ld: warning: directory not found for option '-L/Users/.../Sources/GoogleAnalytics'

It happens because I work with the project on different users.
