Do you want to become a professional iOS developer but are not aware of the skill-set you would need to succeed in the iOS app development industry? Let’s this post explain all this.

When you prefer to be a developer, you always have high growth chances and limitless opportunities. Thanks to ever-rising usage of iPhone, iPad and iOS apps. But it’s not easy to become a successful iOS app developer. It requires a developer knowing almost everything about iOS app development. Here are things you need to have experience in:


Swift is emerging as one of the powerful programming languages. Apple has provided it as open source; primary for iOS, and Mac application development. But it can be used in developing other sorts of apps too. It’s a vast language but if you know about following subjects, you would be able to code iOS apps:

  • Basic Syntax
  • Control Flow (If and Switch Statements)
  • Optionals
  • Objective-C Interoperability
  • Classes, Inheritance & Initialization
  • Error Handling

Spatial Reasoning

Developers must know about spatial reasoning – the ability to think in terms of 3D while envisioning spatial relationships between objects.  To become a professional iOS developer, one needs to focus on creating an interface for Apple’s platforms like iPhone, iPad, Watch, TV in that let users easily interact with an app. You will need learning about inputs or types of controls available on each platform and, how an app can be created around them to take their advantages.

Design Guidelines

What makes the most popular iOS app such popular is its intuitiveness. The key reason is that every single app needs to adhere to strict Apple’s app development procedures and guidelines.

Also, there are specific ways to process and display data on-screen. To become a developer, you would need learning about that too. You need to learn the design guides and patterns to have the ability to add intuitiveness to apps. 


First come up with an app without any web connectivity before linking networking to it. Of course it’s hard to design an app with this feature because almost all apps do interact with the web. But doing so is important to understand the sending / receiving data over the web. To do that, you would need to be familiar with JSON – JavaScript Object Notation. It may seem complex for the first time but, it is a straightforwardly standard data-interchange format.

Core Data

Developed by Apple, Core Data is a framework which primarily operates by storing data on Apple’s devices. Core Data helps developers bring the ability of saving game’s progress. An example of it can be understood from the old video games like Super Mario Bros. It was quite frustrating to start the game all over again when you turned it on again.

Grand Central Dispatch

You will need learning about Grand Central Dispatch which is used in providing an app with the ability to perform multiple operations at the same time. It is quite important to have knowledge about Grand Central Dispatch as highly-populated apps have a number of tasks and to do that, these apps require gathering data from the web, then displaying it on-screen, understanding user’s touch inputs, etc.
