[AC-6105] Cannot use Swift framework with umbrella public header

I'm attempting to use GiphyCoreSDK, a swift framework with public objective C header. I have no problems when I use the file in a native objective C module as long as I include the umbrella header. If attempt to do likewise in Hyperloop, an exception is thrown.

import {GiphyCore} from "GiphyCoreSDK";
GiphyCore.configureWithApiKey('api_key');
$.index.open();

configureWithApiKey is a class method of GyphyCore. Similar error occur if a try to instantiate any of the framework classes and invoke an instance method. The error message is *Cannot find class with name: GiphyCore* I've built the framework using Carthage and saved it to app/platform/ios
