Guidance on API Auth

Hi, I'm going in loops, I need some help please.
I'm going to use sql for DB, Node.js for API and SwiftUI for front end.

I'm aware of Alamofire to do http requests, but I'm lost:

Once I check the token for the user login matches, how do I keep the user logged in? Do I have to store it somewhere?
