How to develop native ios app with existing Rails app as backend?

Question

I'm working on a service which can let users create simple profiles.

It was made by reference to Ruby on Rails Tutorial( https://www.railstutorial.org/ ).

It can authenticate users simply with email and password.(without devise)

Question:

1. How to authorize users from ios in my Rails app?
2. How to post article to my Rails app from ios app?

Environment:

• Rails 4.2
• Swift 2.0

I would like to know the details of authentication flow and sample code.

1. Your users can auth by sending their email and password using a HTTP secure post request. The response would be a token that they can use for all future requests.

2. Your iOS app can make a secure HTTP POST to a resource like /api/posts . The API Posts controller would create a new Post from the params.
