How to become an iOS Developer
Hiring managers for iOS roles care about one thing more than your degree: an app they can download and poke at. You build iPhone and iPad apps in Swift, you ship them through App Store review, and you keep them working every time Apple changes the rules. Here's how people actually get their first role, and what to put on the page so a recruiter keeps reading.
What the work looks like once you're in
Most of your week is spent in Xcode. You'll build screens in SwiftUI, or in UIKit if the codebase is older, wire them to a backend API, and write the code that caches data so the app doesn't feel slow on a bad connection. A good chunk of time goes to things users never see: crash reports in Firebase Crashlytics or Sentry, memory leaks you track down with Instruments, and flaky UI tests that fail only on the build server.
The part people underestimate is the release cycle. You don't push a fix and walk away. You upload a build through App Store Connect, send it to testers on TestFlight, and wait for Apple's review, which can reject you over a privacy label or a login flow. When Apple ships a new OS version each fall, something in your app will break, and you'll spend the beta season finding out what.
Some people love that rhythm. Others find it maddening to have a gatekeeper between their code and their users. If the second group sounds like you, web work might suit you better.
Four ways into your first iOS role
Ship your own app to the App Store
This is the route that works most often for people without a computer science degree. Build something small but real: a habit tracker, a recipe scaler, a transit times app for your city. Use SwiftUI, pull data from a public API, persist it with SwiftData or Core Data, and get it approved. A live App Store link beats a GitHub repo nobody runs, because it proves you got through review, handled signing certificates, and wrote a privacy policy.
Move over from web or backend development
If you already write code for a living, ask to pick up tickets on your company's iOS app. Mobile teams are often short-handed, and a backend engineer who can fix an API contract and the Swift code that calls it is useful fast. Work through Apple's own SwiftUI tutorials and the Swift language guide at night, then volunteer for the next small feature.
Finish a computer science degree with an internship
A degree still opens doors at larger companies with structured new-grad hiring. The degree alone won't carry you, though. Aim for a mobile internship before your final year, and build at least one app of your own so you have something concrete to talk about besides coursework.
Take a mobile bootcamp, then keep building
A focused iOS bootcamp gives you structure and a cohort to learn with. Treat the graduation project as a starting point, not a finished portfolio. Hiring managers have seen a lot of the same weather app and to-do list, so add a second project that solves a problem you actually have.
Words iOS postings keep using
Recruiters and applicant tracking systems match on exact terms, so if you've used SwiftUI, write SwiftUI, not just mobile UI frameworks.
Turning a vague résumé line into one that gets read
Worked on the iOS app and fixed bugs.
Rebuilt the checkout flow in SwiftUI and cut crash-free session drops from 1.8% to 0.3% over 2 releases; app rating went from 3.9 to 4.6.
What separates a junior hire from a pass
Portfolio apps often look fine on the surface and fall apart when someone opens the code. A reviewer will check whether your networking layer is separate from your views, whether you handle a failed request with something better than a blank screen, and whether there's a single test anywhere. You don't need perfect architecture. You need to show you know where the seams are.
Accessibility is the quiet differentiator. Run your app with VoiceOver turned on and Dynamic Type at the largest size before you share it. Plenty of candidates skip this, and the ones who don't get noticed.

Questions people ask
Do I need a Mac to become an iOS developer?
Yes. Xcode only runs on macOS, and you need it to build, sign and submit an app. A used MacBook Air with Apple silicon is enough to learn on. You'll also want a real iPhone for testing, since the simulator hides problems with performance, the camera and push notifications.
Should I learn SwiftUI or UIKit first?
Start with SwiftUI. It's what Apple is building toward and what new projects use. Learn enough UIKit afterward to read it, because a lot of production apps still have older screens built with it, and you'll be asked to fix them.
Is Objective-C still worth learning?
Not as a first language. You'll run into it in older codebases and some third-party libraries, so being able to read it helps. Writing new Objective-C is rare, and most teams would rather you spend that time on Swift concurrency.
Do I have to pay to publish an app?
You need a paid Apple Developer Program membership to put an app on the App Store or distribute it through TestFlight. You can build and run apps on your own device for free while you learn, so hold off on paying until you have something close to ready.
