por Do you already know what the MVVM pattern is in Swift? If you are part of the world of technological development, you probably already know about architectural patterns, such as MVVM in Swift. This is implemented in order to make it easier to separate user interface development from backend.
So, if you are interested in learning more about the MVVM pattern in Swift, You should stay in this article to discover what its characteristics are. and more relevant utilities.
What is the MVVM pattern?
Before delving into the MVVM pattern option in Swift, it is important to be very clear about what this design model, known as the pattern, is and how it works. Model-View-ViewModel. Aims carry out the separation of the user interface sectionalso known as Viewof the logical part or model.
So the objective of this architectural pattern is to make the visual aspect of the system completely visible.
It should be noted that, to implement the MVVM pattern, it is necessary to understand how to factor the app code into the correct classes, as well as have knowledge about its interaction with design elements.
MVVM pattern in Swift
So, the MVVM pattern in Swift works by separating the application into three layers. These are the business logic layer, the presentation logic and the graphical interface. So the ViewModel will represent the state of the view, managing its components and states.
Similarly, the View component in the MVVM pattern in Swift is represented by different resources, such as the UIViewController, together with .xiby type files, which are characterized by only displaying prepared data.
For its part, the ViewModel is responsible for hiding what is related to the asynchronous network code, as well as the code for preparing information for visual presentation and so on. This process is carried out through an established and modeled API, so that it can be effectively adapted to that specific view.
Advantages of using the MVVM pattern in Swift
As an advantage or benefit of implementing the MVVM pattern in Swift, it is found that it allows testing, that is, because the ViewModel includes resources like NSObject or struct and it is not coupled with UIKit code, It is possible to test it more easily in the so-called unit tests or unitest, without this having any kind of negative impact on the user interface code.
In addition to this, the application of MVVM pattern in Swift makes the UIViewController simplerwhile allowing the ViewModel to act by binding the model and the view.
Another advantage of implementing this architectural pattern in Swift is that Those in charge of the development and design of applications have the possibility of carrying out their tasks independently and simultaneously, each one in its components. Therefore, on the one hand, developers will be able to carry out their activities related to the view components and the ModelView, and on the other hand, designers will be able to focus on the management of the view.
What is the next step?
In this article you have been able to learn everything related to the MVVM pattern in Swift, including its most relevant characteristics and implementation advantages. Now, if you have reached this point, you surely want to continue learning about this and other useful options in mobile development that allow you to become an expert.
