iOS developers
Rates, hiring difficulty, a hiring guide and interview questions for an iOS developer: everything in one place.
Overview
iOS developers build native iPhone and iPad applications using Swift and Apple's development frameworks. Modern iOS development centers on SwiftUI for UI, Combine for reactive programming, and Swift concurrency (async/await) for handling asynchronous work. They navigate Apple's ecosystem — App Store guidelines, push notifications, in-app purchases, and platform-specific design patterns.

What an iOS developer costs
Contract and salary benchmarks for the US.
Contract rate
C2C or 1099, from W-2 hourly × 1.3–1.6 for tax, benefits and overhead.
W-2 equivalent
BLS median for US software developers ($135,980), adjusted +8% for iOS using Stack Overflow 2025 pay data (243 respondents).
Full-time contractor cost
Per year at 40 hours a week.
Agencies typically bill 2–3× W-2 pay. See what a full project costs, compare W-2, 1099 and C2C, or check rates by state.
How to hire an iOS developer
What good looks like, and what should worry you.
Typical projects
- Native iOS applications for consumer or enterprise use
- iPad productivity applications
- Apple Watch companion apps
- Integration with device capabilities (camera, ARKit, HealthKit, CoreML)
- Migration from UIKit to SwiftUI
Team setup
iOS development requires dedicated Apple hardware and ecosystem knowledge that can't be faked. For a new app, a senior iOS developer can build and ship an MVP solo. For a mature app, teams of 2-4 iOS developers with a lead are common. If you also need Android, consider whether to hire separate native developers or use cross-platform (Flutter, React Native) — native is better for complex apps with heavy device integration, cross-platform is better for simpler apps where time-to-market matters.
What to look for
- SwiftUI proficiency for new projects — UIKit for legacy codebases
- Swift concurrency model: async/await, actors, structured concurrency
- App Store submission experience — understanding guidelines prevents costly rejections
- Core Data or SwiftData for persistence, plus networking layer design
- Accessibility support: VoiceOver, Dynamic Type, reduce motion
Red flags
- Only knows UIKit with no SwiftUI experience — SwiftUI is the future of iOS development
- No understanding of memory management (retain cycles, weak/unowned references)
- Can't discuss app architecture: MVC is fine but should know MVVM, TCA, or Clean Architecture
- Has never dealt with App Store rejection — it happens to everyone, and experienced developers know how to handle it
- No testing: XCTest, UI testing, snapshot testing
Interview questions
Questions that separate strong candidates from people who just list the keyword.
- How do you architect a SwiftUI app? Walk me through your data flow from network to UI.
- Explain Swift's concurrency model. How do actors prevent data races?
- How do you handle offline-first functionality? Discuss syncing strategies.
- What's your approach to dependency management? SPM vs CocoaPods in 2026.
- A user reports the app is draining their battery. How do you diagnose and fix this?
Hiring trend
How often iOS appears in startup hiring posts over time.
Hacker News “Who’s Hiring” posts mentioning iOS, by year (2015–Feb 2025). Peak: 2017 with 861 posts. HN hiring overall has fallen since 2019, so compare stacks rather than reading absolute numbers.

Questions
How much does an iOS developer cost?
Contract iOS developers typically bill $92–113/hr (C2C or 1099). The W-2 equivalent salary is about $147,400. Agencies usually charge 2–3× W-2 pay.
Is it hard to hire iOS developers?
iOS is not yet in our hiring difficulty index; related stacks are listed on this page.
Should I hire a full-time iOS developer or use a contractor?
If the work is ongoing and core to your product, hire. If you need to start quickly, cover a gap, or the role is hard to fill, a contractor or agency gets work moving while you search.
