How to Become a Professional iOS Developer on Your Own

If you begin a journey in developing iOS apps, you’re immediately immersed in more job opportunities than you can imagine. In today’s society, iOS app developers are desired in most businesses; regardless of how skilled they are.

Even though iOS development skills are highly required and high salaries are offered in return, that’s not all of its benefits. Learning this skill can be as much of a challenge as it is amusing. There is no end to app development and you can always become a better version of yourself than yesterday. In spite of your skill level, you can always find an honorable job in tech companies, non-tech businesses or simply working as a freelancer. If you’re also curious about how to become an iOS app developer, keep reading this article to the end.

What Does an iOS Developer Do?

iOS app Development includes code applications for mobile apple products, including iPhones, iPod Touches and iPads. To be a successful iOS developer, you need to be fluent in the coding languages of C, C++, Objective-C or Swift.

Basic Requirements to Become an iOS Developer

What do you need (as the bare minimum) to have before you can start to learn iOS app development? Let’s go through it all from equipment to programming languages.

Basic Requirements for an iOS Developer

Mac Computers

Attaining a Macintosh computer is a priority to learn iOS app development. All of the software that you can design an iOS app with can only work on computers that have Mac as their operating system. So having a computer that runs on Mac is a basic requirement. Can you run macOS on non-Apple computers? Yes. But you’ll need a license from Apple, which is hard to get by and not worth the trouble. So to put it shortly, if you want to design and launch an app on the App Store, you should have a Mac computer.


Xcode is another crucial skill that you should master in order to learn iOS app development. Having a superior mobile app with a satisfying user experience is only possible through Xcode IDE. Xcode turns your ideas into code and attracts users with it.

Developers can also use Xcode to attain various Apple services. Some of these services include Game Changer and Passbook. So as an iOS app developer, you need to be well versed in Xcode IDE.

Apple’s Xcode is the first software that you should install on your MAC computer and probably the most important one. It’s on the App Store and it’s completely free. As an Integrated Development Environment (IDE), Xcode offers many development tools that are necessary for you. Some of these tools include instruments, simulator, and debugger.

Xcode is universally considered a comprehensive system that helps you every step of the way; from designing and testing your iOS app to submitting and launching it on the App Store. One last virtue of the Xcode is that it contains multiple templates on which you can design apps for various devices. These templates can help you a lot and make the app development process straightforward and trouble-free.


To learn iOS app development, Swift is your best option, as it’s the best programming language in the field. If you design an application based on Swift, it will only run on devices with iOS 7 or higher. But you don’t need to worry. Because 92% of iPhones that have been manufactured by Apple in the last 4 years have iOS 13 as their operating system. Swift runs on the LLVM compiler, which is open source. This programming language is multi-paradigm and has specific protocols.

If you’re not proficient in programming languages and lack experience in the field, learning various object-oriented commands and ideas will help you immensely. This way you can begin your Swift programming career and become a coding professional. With the help of Swift Playgrounds, you can learn the principal concepts and commands.

Being familiar with Swift 3.0 is essential for iOS development. Apple owns this programming language and it has been used for years to create and develop iOS mobile applications. So if you want to learn iOS app development, Swift 3.0 is a necessity for you.

As a universal programming language, all iOS mobile apps use Swift 3.0 and are developed by it. Learning a new programming language can be challenging and troublesome, but don’t worry. Basic knowledge of this language and its functionalities is enough to get you started. Some of these functionalities include: Classes, Inheritance & Initialization, Control Flow (If and Switch Statements), Optionals, Basic Syntax, Objective-C Interoperability, and Error Handling.


If you want to become a skilled iOS app developer, you should put learning Objective-C on your agenda. This programming language played a key role in Apple’s app development. When Swift was presented to the world, it managed to take Objective-C’s place. So many people would advise against learning this language. But since this language has been Apple’s primary programming language, learning it will help you gain perspective on the basics of coding.

Both Swift and Objective-C can be used together as CLang, a front end which parses C, C++, and Objective C code, can translate all of the languages and convert them into a representation suitable for LLVM.

Data Transfer and Networking

Understanding networking or the way data is sent and received Is a Key Factor for iOS app developers. So you’ll need to be familiar with JSON- JavaScript Object Notation. It’s fairly standard And straightforward for interchanging data.

Developing Framework

Have you wondered why Apple products are so alluring? If you ask Apple users they’ll all probably point out the intuitiveness of the devices. When it comes to developing iOS apps, particular procedures and predetermined guidelines are there for you to follow.

So by all means, learn iOS app development, be creative and create wonders and novelties, but ultimately you should stick to the Apple design guidelines. If you master this art, the magic you can create will surprise you.

Spatial Reasoning

When it comes to developing an app, spatial reasoning is an essential ingredient. Without imagining the point of view of the app user, how can you ensure that you’ve done a good job?! How users interact with the app and the satisfaction they get from it, is ultimately what matters the most.

So whether you like to learn iOS app development or any other app development, spatial reasoning comes in handy. Putting yourself in the user’s shoes will help you gain perspective. This way you can develop an interface and embed functionalities in it that are more comprehensive, productive, and accessible. So visualization is the life and soul of your work.

Core Data

Nothing can be more agitating for users when their data washes off unsaved, so they’ll have to start all over again when they reopen the app. The solution to this problem is Core Data. Core Data stores users’ data on Apple’s devices and makes sure they don’t come across this problem again.

Apple Human Interface Guidelines

If you want your iOS app development experience to be easy-breezy, immerse yourself in Apple Human Interface Guidelines. With the help of these Guidelines, your apps will reach their maximum potential with an astonishing user experience.

UI and UX Developing Journey

When designing a web app or a mobile app, UI and UX are intertwined and related in a way, but when it comes to their functionality, they somewhat part ways. In simple words, when you’re designing the way users use the app, you’re working on UX. When it comes to how the app looks, it’s UI. If you effectively pull off a superb UI/UX design when making your mobile app, the results will be phenomenal and aesthetically pleasing. This will lead to more user engagement as your ultimate goal.

So, as an iOS app developer, you should try to master captivating design concepts and produce creative ones as well.

Now, if you’re looking for a job as an iOS developer, here’s a bit of information about your duties as an iOS developer and also your responsibilities.

Duties of an iOS Developer

An iOS developer’s first and foremost responsibility is to develop applications for Apple devices based on the iOS operating system. They should also combine and connect the application to backend services. But simply designing an application is just the surface of their duties.

IOS developers are still responsible for their creation after the app has been launched. They should ensure that their app is organized and carries on with the same code quality and automatization. A professional app developer should have mastered more than one programming language concerning iOS devices. Some of these languages include C-Objective and Swift. Last but not least, being a team player is a key factor that indicates a professional iOS developer. There are always different developers that work on various sections of the app’s design.
