Role summary

An iOS Developer owns our native iPhone and iPad application: building screens in SwiftUI and UIKit, modeling local data with Core Data or SwiftData, wiring up networking with async/await, keeping the app fast and leak-free through Instruments, and shepherding every release through code signing, TestFlight, and App Store review. They collaborate with designers, backend engineers, and QA to turn specs and API contracts into shipped, accessible native experiences.

Responsibilities

Must-have skills

  • • 3+ years shipping production iOS apps in Swift, at least one of them live on the App Store.
  • • Fluency in SwiftUI and working competence in UIKit, including bridging between the two.
  • • Solid grasp of Swift Concurrency (async/await, Task, actors) and how it replaces older completion-handler and GCD patterns.
  • • Hands-on Core Data or SwiftData experience, including background contexts and model migrations.
  • • Comfortable with memory management, ARC, retain cycles, and profiling in Instruments.
  • • Experience with code signing, provisioning, TestFlight, and the full App Store submission process.
  • • XCTest and XCUITest experience and a CI setup (Xcode Cloud, GitHub Actions, or Bitrise).
  • • Strong written English for async code review, spec docs, and Slack threads.

Nice-to-have skills

  • • fastlane match for shared code signing across a team.
  • • WidgetKit, App Intents, or push notification (APNs) experience.
  • • StoreKit 2 for in-app purchases and subscriptions.
  • • A published personal app on the App Store.
  • • Familiarity with a cross-platform layer (React Native or Flutter) for hybrid codebases.

Tools and technology

Reporting structure

Reports to the Engineering Manager or Mobile Lead. Collaborates daily with product designers (Figma handoff), backend engineers (API contracts), QA, and the product manager for the feature area.

Seniority variants

How responsibilities shift across junior, mid, and senior levels.

junior

1-2 years

  • • Implement scoped SwiftUI screens against design specs under review from a senior.
  • • Write unit tests for view models and fix bugs surfaced by QA and crash reports.
  • • Learn the codebase conventions: state patterns, navigation, and PR etiquette.
  • • Handle accessibility and layout fixes across screen sizes and Dynamic Type.

mid

3-5 years

  • • Own end-to-end delivery of a feature area from design to App Store.
  • • Make data-layer and concurrency decisions for new features.
  • • Cut TestFlight builds and manage submissions through review.
  • • Review pull requests from junior engineers and enforce the memory-safety bar.

senior

6+ years

  • • Set the app architecture: module boundaries, navigation, state, and persistence strategy.
  • • Own the release pipeline, signing, and the SwiftUI-versus-UIKit migration roadmap.
  • • Mentor mid-level engineers and run the iOS hiring loop.
  • • Drive SDK and OS-version upgrades and manage the deprecation backlog.

# iOS Developer — Job Description

## Role summary
An iOS Developer owns our native iPhone and iPad application: building screens in SwiftUI and UIKit, modeling local data with Core Data or SwiftData, wiring up networking with async/await, keeping the app fast and leak-free through Instruments, and shepherding every release through code signing, TestFlight, and App Store review. They collaborate with designers, backend engineers, and QA to turn specs and API contracts into shipped, accessible native experiences.

## Responsibilities
- Build new features and full screens in SwiftUI, dropping to UIKit where a control or behavior is missing, with unit and UI test coverage.
- Maintain and incrementally migrate legacy UIKit view controllers, using UIHostingController and UIViewRepresentable to bridge the two frameworks.
- Model local persistence with Core Data or SwiftData, including background contexts, merge policies, and safe lightweight migrations between model versions.
- Wire up networking with URLSession, Codable, and async/await, with structured error handling, retries, and offline behavior.
- Manage app state cleanly with observable objects and the @Observable macro, keeping view models testable and free of view-layer coupling.
- Profile with Instruments to eliminate dropped frames, memory leaks, and retain cycles, and keep long lists scrolling at 60 to 120 fps.
- Own the release pipeline: certificates, provisioning, code signing via fastlane, TestFlight distribution, and App Store submission.
- Meet accessibility standards on every screen with Dynamic Type, VoiceOver labels, and sufficient contrast, verified on device.
- Respond to App Store review rejections with concrete fixes for privacy manifests, App Tracking Transparency, and content guidelines.
- Write XCTest unit tests for view models and data logic plus XCUITest flows for critical paths, and keep CI green on every PR.
- Review pull requests from peers with specific feedback on memory safety, concurrency, view lifecycle, and API design.
- Partner with backend engineers to shape REST or GraphQL contracts before implementation so the app is never blocked on API shape.

## Must-have skills
- 3+ years shipping production iOS apps in Swift, at least one of them live on the App Store.
- Fluency in SwiftUI and working competence in UIKit, including bridging between the two.
- Solid grasp of Swift Concurrency (async/await, Task, actors) and how it replaces older completion-handler and GCD patterns.
- Hands-on Core Data or SwiftData experience, including background contexts and model migrations.
- Comfortable with memory management, ARC, retain cycles, and profiling in Instruments.
- Experience with code signing, provisioning, TestFlight, and the full App Store submission process.
- XCTest and XCUITest experience and a CI setup (Xcode Cloud, GitHub Actions, or Bitrise).
- Strong written English for async code review, spec docs, and Slack threads.

## Nice-to-have skills
- fastlane match for shared code signing across a team.
- WidgetKit, App Intents, or push notification (APNs) experience.
- StoreKit 2 for in-app purchases and subscriptions.
- A published personal app on the App Store.
- Familiarity with a cross-platform layer (React Native or Flutter) for hybrid codebases.

## Tools and technology
- Swift
- SwiftUI
- UIKit
- Xcode
- Core Data / SwiftData
- Swift Concurrency
- XCTest / XCUITest
- Instruments
- fastlane
- TestFlight / App Store Connect

## Reporting structure
Reports to the Engineering Manager or Mobile Lead. Collaborates daily with product designers (Figma handoff), backend engineers (API contracts), QA, and the product manager for the feature area.

## Success metrics (KPIs)
- Crash-free session rate held above target (tracked in Xcode Organizer or Sentry) release over release.
- App Store review pass rate on first submission, with rejections trending toward zero.
- Scroll and launch performance within budget, verified in Instruments before each release.
- Weekly PR throughput and review turnaround on own and peer PRs.
- Test coverage on view models and critical UI flows maintained or improved each sprint.
- Accessibility: zero critical VoiceOver or Dynamic Type defects in shipped screens.

Frequently asked questions

What does a iOS Developer do day-to-day?

An iOS Developer owns our native iPhone and iPad application: building screens in SwiftUI and UIKit, modeling local data with Core Data or SwiftData, wiring up networking with async/await, keeping the app fast and leak-free through Instruments, and shepherding every release through code signing, TestFlight, and App Store review. They collaborate with designers, backend engineers, and QA to turn specs and API contracts into shipped, accessible native experiences.

How many years of experience should a mid-level iOS Developer have?

A mid-level iOS Developer typically has 3-5 years of experience. At that level they should own end-to-end delivery of a feature area from design to app store.

Which KPIs should I hold a iOS Developer accountable to?

The most important KPIs for a iOS Developer are: Crash-free session rate held above target (tracked in Xcode Organizer or Sentry) release over release.; App Store review pass rate on first submission, with rejections trending toward zero.; Scroll and launch performance within budget, verified in Instruments before each release.; Weekly PR throughput and review turnaround on own and peer PRs..

Do your iOS developers write SwiftUI, UIKit, or both?

Both, and we match on what your app actually uses. Most production iOS apps today are mixed — a SwiftUI shell around older UIKit view controllers, or the reverse — so we shortlist developers who are fluent in both and comfortable bridging between them with UIViewRepresentable and UIHostingController. If you are starting greenfield in pure SwiftUI, we match a developer whose recent work is SwiftUI-first. If you are maintaining a large UIKit codebase and migrating screen by screen, we send someone who has done exactly that migration, not someone who has only read about it.

Can they handle App Store submission and code signing, or just write code?

They handle the full release path. Certificates, provisioning profiles, code signing, TestFlight distribution, and App Store review are all part of the job, and we screen for developers who have shipped apps to the store rather than only pushed to a simulator. Most of ours run signing through fastlane match so the whole team shares one source of truth instead of fighting Xcode over expired profiles. They also know how to answer a review rejection — privacy manifest questions, App Tracking Transparency prompts, or a guideline 4.3 spam flag — with a real fix rather than a resubmit-and-hope.
