What Does an iOS App Developer Do? 

An iOS app developer is responsible for creating apps for mobile devices that run on Apple’s iPhone Operating System (iOS). An iOS app developer builds, tests, and fine-tunes applications for such devices. Normally, iOS app development uses one of two programming languages, Swift or Objective-C.

Mobile games.

Gaming apps are the most popular category of app that Apple run. An iOS app developer specialising in game development can be employed by app development companies, work independently, or partner with other developers for each specific gaming project.

Productivity apps.

Productivity apps are designed to help solve problems or do things more efficiently. Evernote, for example, is a note-taking app that stores text, links, images, and files. The Grammarly app checks your writing for grammar mistakes and makes suggestions for improvements.

Business applications.

Many businesses now rely on apps for inventory management, billing, or customer relationship management. iOS developers can be employed by companies to work on apps that support such essential business functions.

Where do iOS developers work?

iOS developers can work for a company directly, freelance, or be self-employed. Nowadays, a lot of iOS developers work remotely. iOS developers can work in several fields as many industries rely on apps for customer relations or product support. Finance, technology, and retail are now probably the top industries which employ iOS developers.

Necessary skills for iOS developers:

Non-technical skills.

iOS app developers must be good team players. It’s also important for an iOS developer to be patient, flexible, well-organised, motivated, able to communicate well, and able to work well under pressure.

Technical skills.

For an iOS app developer proficiency in Swift and Objective-C is essential. They should also be familiar with Xcode, Apple’s integrated development environment (IDE). Xcode helps developers write code and assemble apps for use on different devices and operating systems. It is also used to design, code, test, and debug an app before it is made available in the App Store. An iOS app developer must also understand Apple’s human interface and design guidelines as these are specific attributes for all apps made available in the App Store.

iOS programming languages.

The programming language Swift was created as a general-purpose language using state of the art safety, performance, and software design patterns in 2014 to be the best available programming language for a range of projects. Swift is one of the more efficient languages for creating iOS applications. In fact, apps built with Swift can be used on devices dating back as far as iOS7. Swift is also compatible with Objective-C, the other most widely used language for creating iOS apps. Objective-C is also a general-purpose programming language. It was introduced in 1984 and was the main language used by Apple before the creation of Swift. It still constitutes a significant part of Apple’s codebase.

Starting out as an iOS developer.

There are different pathways for becoming an iOS app developer, but first, you should take an iOS app developer certification course in Swift or Objective-C. This will help you understand the programming language, frameworks, and the concepts used in iOS development.
