Day-to-Day Responsibilities
Turn product designs and wireframes into working app screens using Swift with SwiftUI or UIKit.
Connect the app to back-end services through REST APIs and handle data, login and offline storage.
Test on real iPhones and iPads and in the Xcode simulator, then fix crashes, bugs and slow performance.
Follow Apple's Human Interface Guidelines so that the app feels natural to iPhone users.
Prepare builds, submit them through App Store Connect and respond to any feedback from Apple's review team.
Update apps for each new iOS release. Apple introduced iOS 27 at WWDC 2026, and it was released to the public on 14 September 2026, so developers must check their apps against new features.
Work with designers, testers and product managers, and keep code organised in Git so that teams can collaborate safely.
