How to add registration to ios application?

Question

User identification

I am creating an application in which registration will be required. I want to do a regular registration and log in as usual, and also a guest mode where you can enter the application without registration and see its main functions. What is needed for this? Is it possible to get by with one knowledge of swift or something else? Do I need to connect the Internet or can I do without it? I write the clarification in swift in Xcode only for iPhone and iPad.

Answer 1

Internet, of course, will be needed. Your users must be stored somewhere, therefore, you need a backend on which the login and registration services will be launched. Use your own or third-party backend, such as parse, firebase, etc.
