What‌ ‌Does‌ ‌iOS‌ ‌Development‌ ‌Entail‌ ‌

When someone mentions “iOS Development,” many things come to mind. For instance, the iOS device is a mobile operating system created by Apple Inc. Initially, it was a software platform meant to run on personal computers, but with the launch of the iPhone in 2007, it became an altogether different platform to be reckoned with. Today, iOS is one of the leading mobile operating systems globally, having more than 1.3 billion active devices all over the world.

It’s a given that the world of mobile apps, and more specifically, iOS development, has seen tremendous growth. iPhone and iPad users have been demanding new and improved apps in every field of interest. And, it’s not just about the number of apps getting created for the iOS platform, but the quality of these applications.

As a result, many organizations have stepped up to produce quality apps for their target audiences. In addition, these apps are being developed with cutting-edge technologies. This further adds to the popularity of iOS development as this is one platform where developers can use modern tools and techniques to write applications.

But, as you may already know, creating quality apps takes time and skill. Therefore, you may be wondering what does iOS development entail?

You’ll find many different skills involved in creating an app for any platform. However, the two most essential areas usually include:

Designing – involves creating wireframes or mockups that show how an app will look onscreen; this is an essential step since it is when the client/developer clearly defines the objectives or goals of the app.

Development – this is when all the skills mentioned above come into play: programming languages (Objective C), design patterns (MVC), which Apple expects all its designers to follow.


The Swift Programming Language

Swift is a safe, fast, and interactive programming language for iOS and OS X development. Swift builds upon the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming more accessible, flexible, and fun.

There are three critical characteristics of Swift: it is safe, flexible, and fast.

Swift is a type-safe programming language that prevents many memory management errors while simultaneously eliminating the need for manual reference counting.

The type of safety in Swift helps you avoid incorrect code without writing extensive tests or documentation. This makes your code safer without making it slower or harder to read.

All of your code runs within the safety of the Swift runtime, so there’s no unsafe code to test or debug.

Swift is also designed to scale from “hello, world” to an entire operating system. So as your projects grow and become more complex, Swift provides simple ways to scale your codebase while keeping it easy to read and maintain.


Mobile – View – Controller

MVC is composed of separate layers for the user interface (UI), business logic, and data access at a high level. This allows for more precise separation of responsibilities within the application and increased codebase maintainability. It also provides better testability, as you can test UI behavior from the “Controller” layer. In addition, data access or business logic can be tested separately from the UI in their layers. Most importantly, it allows developers to easily reuse these components in other applications.

Taken as a whole, MVC separates an application into three distinct parts: model, view, and controller. The model represents the data an application is working on. It contains all of the business rules and logic that pertain to that data. The view is the visual representation of that data, including all UI behaviors such as event handling or animation associated with the model or controller. Finally, the controller coordinates interactions between a user and the model or view.

Keep in mind that great programmers are prized most highly. The best kind of iOS developer is one who can think critically and solve problems efficiently, make well-considered design choices, and write code that is clear and easy to maintain.
