Developers have in-depth knowledge of how iOS works on different Apple devices, like the iPad, Apple Watch, and iPhone. iOS developers build, test, and fine-tune applications to suit the needs of their clients. Typically, iOS app development is done in one of two programming languages: Swift or Objective-C. You can learn more about what type of software products iOS developers create in the next few sections.

Gaming applications are the most popular category in the Apple app store [1]. A notable example is AFK Journey, the iPhone's game of the year in 2024 [2]. This fantasy role playing game (RPG) was developed by Farlight Games, a video game publishing company for iPad and iPhone. iOS developers specializing in game development may be employed by companies like EA or Ubisoft, work independently, or partner with other creatives for a specific gaming project. You can explore public code repositories, tools, and tutorials for iOS game development on GitHub.

A good productivity app helps you solve a problem or get things done more efficiently. For example, Evernote is a robust note-taking app that stores text, links, images, files, and more. The Grammarly app checks content for grammar mistakes and makes suggestions for improvements to your writing. Creating a to-do-list-style productivity app is an excellent exercise for a novice iOS developer. Although the concept is simple, the execution has plenty of room for expanded features.
Business applications are the second most popular category in the Apple app store [1]. As mentioned above, most businesses rely on applications to handle things like inventory management, billing, or customer relationship management. iOS developers may be employed by companies like Amazon or Etsy to work on applications that support essential business functions.
iOS developers may be employed by a company directly, freelance, or be self-employed. Many iOS developers work remotely, although work-from-home flexibility varies from company to company. iOS developers can work in a variety of fields since most industries rely on applications for customer relations or product support. However, finance, technology, and retail are among the top industries employing iOS developers [3].
While proficiency in Swift and Objective-C is essential, many other skills are desirable for iOS app developers.
"Knowing how to approach and tackle a problem you don't know how to solve is definitely a skill that I've had to constantly use at work," says Mari Batilando, a software engineer at Meta. "Meta's vast reach and scale means it has unique problems that you may not have encountered before. Knowing how to simplify and decompose these problems into smaller, solvable parts is important to contribute and make an impact in the company."
iOS developers must hone their personal development skills to be able to work on a team effectively. Team members may include other developers or employees in other departments, like marketing. At any level, it’s important for an iOS developer to be:
Patient
Flexible
Organized
Self-driven
Able to communicate well
Able to work well under pressure
Here are some technical skills to develop that will help ensure your success as an entry-level or mid-level iOS app developer:
Be familiar with Xcode, Apple’s own integrated development environment (IDE). It aids developers in writing code and assembling apps for use on different devices and operating systems. Xcode is used to design, code, test, and debug an app before sending it to Apple’s App Store.
Know Apple’s human interface guidelines and design guidelines. These are specific attributes that Apple requires for all apps in their App Store.
Once you’ve moved your way up to a Senior iOS Developer position, you'll need to be familiar with:
Software architecture
Concurrency
Reactive programming
Deploying animations
User testing

"As an iOS engineer, most of my experience required me to be knowledgeable in using Xcode, Swift, Objective-C, and a lot of Apple's proprietary iOS tooling and frameworks," says Batilando.
According to the creators of Swift, this programming language was created as a “general-purpose programming language built using a modern approach to safety, performance, and software design patterns [4].” Apple created it in 2014 to be the best available language for developers to use for a large range of projects.
A few other features of Swift include the following:
It is one of the more efficient languages to use when creating iOS applications.
Apps built with Swift can be used on devices dating back to iOS 7 or later.
Swift is compatible with Objective-C, the other most commonly used language for creating iOS applications.
Like Swift, Objective-C is also a general-purpose language. It was introduced in 1984 and based on the programming language C. Objective-C was the primary language used by Apple before the creation of Swift, but it still makes up a significant portion of Apple’s codebase.
On average, an iOS app developer in the US earns an annual salary of $131,000 [5]. Factors influencing an iOS developer's salary include company size, location, experience level, education, and current demand. For example, salaries will likely be higher in larger tech hubs like San Francisco, New York, and Atlanta. A start-up will pay less than a larger company like Uber or Facebook.
As more and more companies look to grow their online presence, the demand for iOS app developers is rising significantly. Apple makes up a significant portion of that demand. According to the US Bureau of Labor Statistics (BLS), the demand for iOS developers is expected to rise 17 percent from 2023 to 2033. This statistic translates into about 451,200 new job opportunities in the US alone [6].
