)
libc++abi.dylib: terminating with uncaught exception of type NSException

I also tried a fresh project to add this SDK but got the same crash.If GoogleConversionTrackingSDK-iOS-3.0.0 is support for iOS 7 or not? Need guidance on what am I doing wrong here or if I am missing something.

Thanks.

Answer 1

This problem appears because google has used categories in static library
The solution is super simple, you need to notify linker about that

1) Click on the project
2) Click on the target
3) Open Build Settings tab
4) Search for Other Linker Flags

5) Double click on Other Linker Flags
6) Add -ObjC and -all_load flags
7)
Remove binary (delete from device/simulator),
Clean project (hitting cmd+shift+k) and
build again (hitting cmd+b).

You're ready to go!
