How to get this working with new xcode version?

I have read this as well:
https://github.com/xinthink/react-native-material-kit/issues/120#issue-140033109


Issue is that new xcode hides **Products** folder and I can't figure out a way to get to **libRCTMaterialKit.a**
I'm new to React Native and I have spent last 2 days trying to figure out how to get project with MaterialKit up and running .

Any help would be appreciated.
