iOS Action Extension, use code from another app

i am building an application that uses frameworks like Alamofire on my API layer, everything so far works like a charm.

I want to also create an Action Extension for this app so that users can save URL's like "Pocket" for example. I need to send this URL to my server using my API class that resides in the Original Project.

I am having a lot of issues reusing that API class along with Alamofire.

Any help would be greatly appreaciated
