A widespread and easy-to-follow iOS application design pattern is the MVC model. We won't be coding anything here, but we'll walk through some MVC projects and discuss best practices.
MVC is a standard software architecture pattern for beginners with the following objects.
The application's data and actions are encapsulated in the Model layer. Several classes make up the application's model, and there is also logic used to manipulate the data to be displayed in the application. In a well-designed iOS application, all the critical data is encapsulated in the model objects. The model object has no explicit link to the user interface in the program. The request and response models are used to parse all the data coming from the server as a get API response or going to the server as a post API request in a dynamic iOS application that makes API calls to get its data on runtime.
