How to Become a iOS Developer

Apple is one of the biggest manufacturers of smartphones in the world. At the start of 2021, Apple CEO Tim Cook revealed that the company had over 1.65 billion active devices in circulation, including over a billion smartphones. Over the years, Apple has proven that its infrastructure will improve, and there will always be a demand for its iconic products.

You can rest assured that learning how to become an iOS developer is a beneficial career move. In this guide, you're going to learn what iOS development entails, the opportunities present within the field, and the different routes available for you to explore in your journey.

What Is an iOS Developer?

An iOS developer is a software developer explicitly trained to build and maintain applications for iOS, the iPhone operating system. Just as Android development deals with Android, the core developers who work at Apple design software for iOS. There are also iOS application developers who build and publish third-party apps on the iOS App Store.

These developers don't just know how iPhones work. They also know how to create applications for iPad, Apple TV, and even Apple Watch. They can work independently or get employed by a company to build and maintain consumer-friendly applications.

iOS Developer Job Description

An iOS developer designs, develops, maintains, and upgrades core or third-party applications for all devices on iOS. They use concepts, frameworks, and programming languages unique to iOS devices. Depending on the level and responsibilities of the developer, they might supervise the entire development process from idea conceptualization to final launch.

As apps run on iOS devices, iOS developers collect feedback from users, monitor performance, debug, and do whatever it takes to ensure that these apps are up to specification. Then, at intervals, they update the code to add new features without compromising quality.

iOS Developer Salary and Job Outlook

The demand for iOS developers is on the rise. The Bureau of Labor Statistics classifies iOS developers under software and web developers, programmers, and testers, and the demand for these jobs is expected to grow by 19 percent between 2020 and 2030.

BLS notes that the average salary of software developers is about $105,310. However, ZipRecruiter reports that iOS developers specifically earn an average of $114,614 per year, with a bare majority of salaries falling between $90,000 and $133,500. The compensation of iOS developers differs across education levels, and varies by location and professional experience.
