Evaluate the Team around the app to create an effective communication channel.Evaluate the essential complexity of the app requirements to avoid accidental complexity.How to choose the appropriate iOS Architecture (Part 1) They also help you create loosely coupled code so that you can change or replace components in your code without too much hassle. They’re templates designed to help you write code that’s easy to understand and reuse. In iOS, the view controller is inseparable from the concept of the view.ĭesign patterns are reusable solutions to common problems in software design. In iOS apps, a view model is a companion object to a view controller. It involves a new concept called a view model.

The lower layers in iOS provide the basic services and the higher layers provide the user interface and sophisticated graphics. It contains an intermediate layer between the applications and the hardware so they do not communicate directly. That ViewController is actually part of the presentation layer and the Model part represents the whole Domain Model, not just some data entity. The main idea of that post is that people simply do MVC in the wrong way.
