Xcode Build error Undefined symbols for architecture arm64: "_OBJC_CLASS_$_GameScene"

I have activated arm7 armv7 arm64 as valid architecture for 64 bit requirement by Apple recently but when I try to build the app in Xcode it throws me this error. I get a warning first for libchartboost.a not being found, I download the chartboost latest folder from their website but it does not have libchartboost.a so I am still using chartboost 3.2.1. But not sure if thats the issue since I get an error related to GameScene below. Am I missing a framework? Thanks for your help.

ld: warning: ignoring file /Users/Administrator/Documents/Software/libChartboost.a, missing required architecture arm64 in file /Users/Administrator/Documents/Software/libChartboost.a (3 slices)

Probably an old thread, but in such linker errors, following step works:

Link all the required frameworks along with Chartboost framework, such as Storekit, Webkit, AVFoundation, Foundation etc.

These are all the frameworks that are used by Chartboost framework to fetch and display ads in media formats (audio and video).

For latest details on how to fully integrate and what all frameworks are required, refer to this guide.
