Skills needed as an iOS developer

How to become an iOS developer

Since Apple’s products are highly popular, iOS applications and programs are consistently in demand. This ensures a promising future awaits you in the market, as every company and group seek to hire an iOS developer rather than a programmer. Need to learn these skills? Don’t worry; let’s examine the fundamental skills required for this profession:

Swift programming language

The Swift programming language is the most popular and official language for developing Apple mobile applications. To become a professional iOS developer, you must acquire sufficient skills in this iOS developer language and understand its structures. Syntax, Objective-C interoperability, Swift classes, and variables are some of the key elements you should master.

Apple Xcode IDE

IDEs are programming environments where you can input programming codes and visualize the outcomes of your work. Apple Xcode is Apple’s official IDE, enabling you to write clean code using variables, prebuilt libraries, and an appealing user interface. Moreover, this program facilitates testing and debugging to identify potential errors. If you plan to write iOS apps, learning how to work with the Xcode IDE is highly beneficial.

Spatial reasoning ability

You can enhance your spatial visualization and reasoning skills through practice and continuous improvement. This ability is considered one of the most crucial skills for a developer. Remember that every program is designed to retain and attract new users. Therefore, you should be capable of understanding and reaching the target users by thinking beyond the app’s design and development. As a developer, your role is to create an app with an intuitive user interface and an enjoyable user experience by placing yourself in the users’ perspective. Remember, making an app more user-friendly and engaging is essential to your role as a developer.

Design rules

One of the reasons Apple products are popular is their uniqueness, which entices users to purchase them. As mentioned earlier, this company has very few open-source programs, and all software is meticulously designed and produced according to the strict framework and rules set by the company. Therefore, it’s essential to understand iOS design rules during your necessary training. With this knowledge, you can design wonderful and flawless applications.

User interface design/user experience

UI and UX are integral components of an app, each serving a different purpose. Users interact with the appearance and layout of the application through UI, focusing on how the application is displayed. On the other hand, UX pertains to the feeling and experience of using the program. Interface/user experience directly impacts the application’s appearance and can significantly affect the interaction with the user. Therefore, as an iOS developer, you must comprehend design rules and concepts. Also, familiarity with iOS design and development rules helps clarify your path and reach the desired result more quickly.

Network knowledge

Another critical skill for an iOS developer is networking. Understanding JSON (JavaScript Object Notation) is essential to grasp how to send and receive information in a network. Additionally, you should acquire sufficient knowledge about other network concepts and secure methods of transmitting and receiving packets.

Data analysis

To develop and enhance applications, application core data is crucial. You should be able to collect, analyze, and interpret this data effectively. Therefore, reading about database analysis is beneficial if you intend to round out your skill set.

Understanding the iOS Platform

Lastly, we will cover the iOS platform in this section. You must familiarize yourself with the platform’s frameworks, patterns, and technologies. Even if you use a language other than Swift to develop applications for this operating system, you should still possess a comprehensive understanding and familiarity with the platform’s nuances and comprehend how all parts work together.

IOS developer language

How to become an iOS developer

iOS programming encompasses several programming languages, each with its own set of advantages and disadvantages. According to this company’s statistics, a staggering 2.5 billion iPhones have been sold to date, drawing many programmers into this field. Below are the recommended languages for programming in this domain:

1- Objective-C

Objective-C is a robust programming language that serves as a thin layer over the C language. Apple utilized this programming language before the advent of Swift. Objective-C finds applications in various domains, including mobile phone applications. Due to its extensive use, many programmers prefer to avoid learning new languages. Consequently, when visiting Stack Overflow, you’ll encounter more programmers proficient in Objective-C compared to similar languages.

Learning the Objective-C language is relatively straightforward, making it easy to begin working with it quickly using self-study materials or resources provided by the creators of this language. Investing time learning this programming language is worthwhile for the next few years.

2- Swift

Swift is a popular Apple programming language known for its high development speed as a compiler language. Unlike Objective-C, Swift boasts enhanced security, faster growth, and reduced errors. It is a versatile language, allowing you to achieve multiple objectives by mastering it.


C# is a potent programming language, often regarded as the fourth most influential globally. Microsoft introduced this language in 2000. It’s important to note that to create an iOS application using C#, you need to utilize the Xamarin framework. Xamarin is a multi-platform framework that facilitates the development of iOS, Android, OS X, and Windows applications using C#. Additionally, Xamarin enables the creation of shared code for iOS and Android applications, streamlining the development process.
