How to integrate Mailchimp api into my iOS Swift app

Question

I have an app I created in Swift with my database built with Parse. I know how to export data from Parse and update my subscriber list for Mailchimp, but how do I have my app automatically update that list when a user creates a new account? I've been researching how but I haven't come across anything that can help me yet. Also everything seems to be in Objective-C. I've used bridging headers before, but I don't know if that will be necessary or not. Any guidance would be a lot of help!

Is it possible to hook into this API endpoint that's part of the Mailchimp API...
