iOS Developer Job Description (2026): Duties, Skills and Salary

An iOS developer builds and maintains apps for iPhone and iPad, writing Swift (or Objective-C on older codebases), working with Apple's frameworks, and shipping through App Store review. They turn designs into working screens, connect to backend APIs, and chase down the crashes and performance issues real users hit.

iOS developers work at companies with a consumer or business app, from startups shipping a first release to large teams maintaining an app with millions of users. The job includes some platform-specific craft, like dealing with Apple's review process and device fragmentation, that doesn't come up on other platforms.

iOS Developer job description FAQ

What does an iOS developer do?

Builds and maintains apps for iPhone and iPad using Swift and Apple's frameworks, connects the app to backend services, fixes bugs and performance issues, and ships releases through App Store review.

What skills should an iOS developer job description require?

Strong Swift skills, experience with UIKit or SwiftUI, comfort consuming APIs, and familiarity with Xcode and debugging tools. CI/CD and SwiftUI with Combine are useful extras, better listed as nice-to-have.

Do iOS developers need to know Objective-C?

Less often now. Most new apps are written entirely in Swift, but developers maintaining older codebases may still need to read or update Objective-C code, so it's worth stating in the job description if the codebase requires it.
