Registration and authorization in Swift 2 iOS application?

Question

iOS

Hello. Tell me, please, sensible material on how to register and authorize in an iOS application. Registration in your service is not through social networks. In theory, even a user is created on the site by the admin and the user is given only a login and password with which he logs in to the application.
If possible, explain the correct concept of such an application. As far as I understand, the data must be encrypted before sending so as not to transfer the login and password to the server in the clear. How to correctly send and receive data if the user has already logged in - send some code of the current session? How to properly manage this session by dropping it after some time of user inactivity?
So many questions :) and so few manuals on the net - mostly primitive examples of authorization directly in the application or through popular social networks. But there is practically no information on how to do this for your service. Especially in Swift. Therefore, I will be glad to any help in this matter. Thanks in advance
