ios app architecture

Ever since the on-demand services have been brought to the fore, the different types of apps have become a new revolution for smartphones that have leveraged users to put all the functionalities right in the pocket. 

As mobile apps have become a new necessity of the current era, the developers too have become intelligent in adopting various methods to build an app. Out of many, deciding on one of the best and most popular iOS app architecture patterns for creating an app has taken a quantum leap in approaching mobile app development.

Today’s article will focus on getting insight into different types of iOS architectural patterns developers maneuver while devising the iOS app for various business verticals.

What is iOS App Architecture?

App architecture is a map of several significant elements that define the framework of an organization’s application solutions that can easily interact and conclude the business and user requirements. Developers devote their time diligently to creating an iOS architecture is by considering mobile app architecture best practices to ensure that applications they are working on are scalable and reliable. 

Choosing certain iOS architecture patterns for your app determines the design of different aspects of the application or software. MVC, MVP, MVVM, and Viper are some most suited iOS architecture patterns that we will know about in detail later in this article.

MVC vs. MVP vs. MVVM vs. VIPER: What is the Right iOS App Architecture Patterns 

When it comes to iOS development tools, the programmers invest highly in creating a verifiable and compatible code structure that all developers can easily understand, which eventually leads the development team to face no difficulties in testing and launching. 

If you aspire to make a productive and fruitful iOS app that stands out in the market, creating iOS and web application architecture patterns would be highly recommended as it provides a solid foundation for your application. 

Let’s look at some widely known architecture patterns iOS developers use.

MVC (Model View Controller): Advantage, Disadvantage & Uses

What is a Model View Controller?

MVC is one of the most recommended and used architecture patterns by iOS developers. The basic objective of using model view controller pattern is to deliver creative UI/UX design services that divide the program logic into three elements, i.e.-

  1. Model – Responsible for data and data access layer.
  2. View – Responsible for graphic display of data.
  3. Controller – Interconnects Model and View component.

Advantages of using MVC Framework

  • Faster development process.
  • Provide multiple views for a model.
  • It can be integrated with the JavaScript framework.
  • Provides high cohesion and groups, specific models.
  • Easy to add a new type of view via MVC.
  • Supports the development of SEO-friendly web pages.

Disadvantages of using MVC Framework

  • Has a complex development pattern, as per some developers.
  • Not suitable for small-scale applications.
  • Frequent changes lead to constant update requests.
  • Strict methodological rule.

Use of MVC model

The question of the century that has already made squirm many developers is – why MVC model for mobile app development lifecycle? Since we have discussed the model view controller in detail along with its pros and cons, the inherent nature of MVC makes it the first and foremost demanded model for iOS app development. 

If you are considering developing an app with a faster process that builds a support system for asynchronous techniques, MVC is a go-to choice. However, MVC’s basic feature, i.e. common mobile app monetization model and controller for all views, makes it a widely acclaimed iOS architecture pattern among developers.

MVP (Model View Presenter): Advantage, Disadvantage & Uses

What is a Model View Presenter?

Model View Presenter (MVP) is another mobile app architecture best practice used by iOS developers for mobile app development. It is an inference of the MVC model. MVP is vastly used for building UI. You can use Flutter for MVP application development. Though it may sound very similar to the model view controller, it is different as MVP has a completely alternate focus. 

Where MVC tries to overlook view logic concerning the controller, MVP moves much of the view logic into the controller, which it calls presenter. MVP involves iOS app architecture best practices. The model of MVP can be divided into four elements, i.e. – 

  1. Model – Responsible for deploying UI elements.
  2. View – Responsible for the graphical display of data.
  3. View Interface – Bridges the gap between model and view.
  4. Presenter – Operates as an interval between the model and view layer.

In MVP, the presenter plays a vital role that is hugely responsible for interacting with the controller and the model.

Advantages of using MVP framework

  • Derivation of MVC makes it easy to adapt by developers.
  • The presenter helps in analyzing the model and view profoundly.
  • A different implementation of view components via modularity.
  • Test units can easily be created as compared to MVC.
  • Explicit separation of responsibilities between components.

Disadvantages of using MVP framework

  • A one-to-one mapping between the presenter and the view could be improbable for development.
  • Unable to limit the UI logic handling.
  • Not suitable for simple and small mobile solutions.
  • Controllers manipulate data models.

Use of MVP model

MVP is beyond model-view-presenter. A coder who works on developing a particular solution mostly uses it to build a user interface with an implementation of .NET, Java, PHP, and many other interoperable programming languages. It was initially created to make module testing easier, but now the developers are using it for mobile app development. 

If we closely look at the MVP’s separate components, we will find how each has a pivotal role in building fine iOS architecture patterns. Moreover, when the developers get into developing a mobile solution that has limited UI elements, Model View Presenter is a viable choice to be considered.

MVVM (Model View- ViewModel): Advantages, Disadvantages & Uses

What is a Model View- View Model?

Whenever a model requires separation of the GUI from the business development logic, the developers prefer to use the MVVM architecture iOS of developing an app. The MVVM offers XAML platforms with an intrinsic pattern, apart from providing a complete view model. There are three basic elements in MVVM i.e. – 

  1. Model – It is a structure that manages the data.
  2. View – Views are responsible for the presentation layer.
  3. ViewModel – works as a mediator between Model and View.

MVP and MVVM patterns are very popular patterns not just for iOS but also for Android development. Caliburn Micro, Prism, and MVVM Light are some popular MVVM android example mobile app development frameworks that developers can use to build an iOS application. In addition, by implementing display control features, MVVM prevents UI from becoming an intractable class.

Advantages of using MVVM framework

  • MVVM patterns offer alternatives to many iOS architecture patterns.
  • Add view models to the mix and provide a better separation of concerns.
  • Breaks alliance between app logic and UI to make testing more accessible. 
  • Separation leads to ease of maintainability.
  • Provides a transparent interface to the view controller.
  • Takes the responsibility of exposing data objects.

Disadvantages of using MVVM framework

  • Not beneficial for simple UI.
  • Data-binding is declarative and difficult to debug.
  • Does not provide a replacement to CodeBehind files.
  • Difficult to put to use by newbie developers.

Use of MVVM model

MVVM is a design pattern aimed at modularising your code for UI architecture in iOS mobile app development. Where other architectural iOS patterns such as MVP & MVC and Swift design patterns make the controllers quite heavy and convoluted, MVVM takes the seat and bridges the vaguely coupled mechanism between all components. 

It also comes out as the most significant consideration for developers. They can perform test-driven development and write down Unit Test Cases for View Models. This eventually gives iOS programmers an idea of where they went wrong while keeping the controllers in code management.

Viper (View, Interactor, Presenter, Entity, and Router): Advantage, Disadvantage & Uses

What is a VIPER?

Finding a suitable architectural solution can be challenging at times. Mainly when you are new to such terms and do not know how each one of the architecture patterns functions and has different benefits to unleash. VIPER, which stands for View, Interactor, Presenter, Entity, and Router, is a model that has five elements to surprise developers with clean architectural patterns. 

While building iOS app architecture patterns with a model that works on modular code-based theory, VIPER is industry-best and unbeatable. The functions of five integral VIPER architecture are 

  1. View – Responsible for exchanging actions between users and the presenter.
  2. Interactor – Carries business logic.
  3. Presenter – Access data from the interactor and send it to the view.
  4. Entity – Carries basic model objects used by the interactor.
  5. Router – Stores the navigation logic.

VIPER steadily wins over other popular iOS architecture patterns in unit testing. Its simple yet impressive distribution of several patterns and components runs easily through the available realization. 

Advantages of using VIPER framework

  • Simplifies complex projects.
  • Best operable architecture for large teams.
  • Disassociates code for reusability and testability.
  • Creates clear and well-defined interfaces.
  • Reduces the number of merge conflicts.
  • It makes the codebase look similar.

Disadvantages of using VIPER framework

  • Developers have noticed a few performance issues.
  • Not compatible with third-party SDKs.
  • Documentation is a bit uneasy to understand.
  • Non-flexible communication between components.

Use of VIPER model

Since VIPER has gained a lot of traction until last year, the developers seem to be impressed by this particular importance of solution architecture pattern. The way it keeps the modules isolated to eliminate any confusion for developers is just phenomenal. Having sufficient knowledge about the architecture pattern is critical for building an over-the-top iOS app for your client. 

Though each pattern has a different and specific purpose of serving, VIPER is practical in fitting each component together logically. VIPER is based on the Single Responsibility Principle (SRP), which developers mostly prefer for a clean architecture of an app.

Three Major Things to Keep in Mind While Choosing Design iOS Architecture Pattern

There are many aspects to consider the best iOS architecture pattern for your next app development; some major ones are given below.

Identify problems with the code – As you embark on an iOS architectural project, the basic necessity is to understand the current state of your codebase and evaluate different architectural patterns based on that.

Focus on strengthening UI code quality – The core objective of app architecture pattern designs is to fix the UI features. Hence, when developers approach object-oriented programming, it becomes important whether the model can handle the component interoperability.

The complexity of app UI – The most crucial part of choosing the best design architecture pattern for iOS lies in knowing the in and out of your app design. The more comprehensively you see the UI design trends, the easier it would be for developers to decide on the right model.

FAQs

Q1. Why is MVVM better than MVC iOS?

The difference between the MVC and MVVM is View and controller. It is responsible for analyzing and assigning the value, so the load is more on view and controller. On the other hand, MVVM is only responsible for setting the value, not determining the value.

Q2. Why is Viper better than MVVM?

VIPER is better than MVVM as it has higher flexibility and testability than other architectures. Therefore, VIPER is better for iOS app developments if you work on a long-term project with well-defined specifications and a plan to reuse parts.

Q3. Which is the most widely adopted architecture for a mobile application?

MVC is considered one of the most popular architecture in iOS mobile web app development solutions.

Q4. Which is better MVC or MVVM?

MVC is better than MVVM architecture for developing intuitive iOS apps. MVVM patterns show a better separation of concerns by adding view models. The view model converts the model layer’s data into the view layer. The controller is no longer responsible for this task.
