How to become an iOS developer
iOS development:

iOS development refers to building, testing, and upgrading the applications used in Apple iOS that align with the company’s and the customer’s requirements. The developer keeps in mind the working of iOS on various devices of Apple such as iPhone, iPad, Apple watch, etc. and makes applications that are compatible with these devices and the demands of the customers.

Is iOS development worth it?

There are about a billion iPhone users and approximately 2 million apps on the Apple Store as of 2021. Mobile applications are expected to generate a revenue of $935 billion by 2023. On average, a person uses 30 apps on his/her iPhone. This shows that there is a huge demand already in this sector, and it’ll be worth it to devote your time to some iOS developer course.

  • Objective-C: a general-purpose, object-oriented programming language based on C used in iOS & OSX products. Even after the introduction of swift, it’s still getting upgraded and hasn’t been replaced yet, so learning it will be smart.
  • Swift: it’s a general-purpose compiled coding language released in 2014. It’s better than Objective-C in performance, type-safety and security. It is used to develop iOS, TVOS, macOS, Linux, and It can run on devices from iOS 7 or later. Swift is the future of iOS development, and hence one should get proper swift training to learn programming in swift.
Other skills:
  • Spatial reasoning: the developer should be able to understand that the application developed will be used by users on different platforms with different types of control & inputs.
  • Design Guidelines: iOS apps must stick to the design guidelines. They should know how to create the Model-View-Controller, delegate patterns and notifications.
  • Networking: Almost every app interacts with the Internet somehow. Thus, it is a requirement for the developer to know about sending & receiving messages on a network using JSON.
  • Core Data: it is the foundation of string any data on an Apple device, which makes it an important part of almost all apps.
  • Grand Central Dispatch (GCD): iOS is known for concurrency, and this too is to add concurrency to the apps developed.

As soon as you have familiarised yourself with the languages and other skills, get on to developing your apps, post them on App Store and keep upgrading them. Pay attention to the app design and maintenance part and stay regular at it. If you’ve taken up some iOS development course, make sure that they make your code and thoroughly practice the development process.
