I'm trying to define a common framework in a project that provides an implementation-agnostic layer. For example, provide a protocol like Analytics and a set of methods/properties as its interface, and provide the implementation through a singleton object so different app targets would use the same implementation.
The issue is when importing the framework from within an app target, a compiler error occurs like so:
import Core // Missing required module 'Firebase'
What needs to be done?
In the Podfile, dependencies are installed only for the framework targets, not the app targets.
