How to hire iOS developers who can get through App Store review

Good Swift is half the job. The other half is getting through Apple. Here's how to test both before you hire an iOS developer.

When you hire iOS developers, you are hiring for two jobs at once. One is writing good Swift. The other is getting that code through Apple: App Store review, privacy rules, signing, TestFlight and the yearly SDK deadline that arrives whether your roadmap is ready or not. Plenty of developers are strong at the first and shaky at the second, and the second is where launches slip.

This guide covers the skills to test at each seniority level, App Store knowledge you can check in an interview, a test task, rates by region and how to choose between a freelancer, a dedicated developer and an agency. If you'd rather start with a vetted team, see how our iOS developers for hire work.

What an iOS developer should know in 2026

Modern iOS work centers on Swift and SwiftUI, but most real apps still touch UIKit somewhere. A strong candidate is comfortable across the whole picture:

• Swift and its concurrency model. async/await, actors, structured concurrency and the stricter data-race checks of the Swift 6 language mode. Ask how they migrated an older codebase, because that is where the hard decisions are.
• SwiftUI, with UIKit when needed. Building screens in SwiftUI is the norm. Knowing when to drop to UIKit for a complex list, a camera view or a legacy screen is what experience looks like.
• Architecture and state. A clear separation between views, state and data, whether they use MVVM, a reducer-style approach or something simpler. The label matters less than testability.
• Networking and persistence. URLSession with proper error handling and retries, and local storage with SwiftData, Core Data or SQLite when the app needs to work offline.
• Apple frameworks your app needs. StoreKit for purchases and subscriptions, push notifications, widgets, HealthKit or MapKit. Match this list to your product, not to a generic job post.
• Testing and tooling. Unit and UI tests, Instruments for memory and launch time, and a working knowledge of Xcode build settings and schemes.

Skills by seniority: what to expect

Titles mean different things at different companies. Use this as a yardstick for what each level should handle without help.

For a first iOS hire on a new product, aim for senior. A mid-level developer can do great work inside an architecture a senior has set up, but rarely should be the one setting it up.

App Store knowledge you can test in an interview

This is the fastest way to separate people who have shipped from people who have only built. Ask about real rules and listen for specifics.

• Account deletion. Apple's App Store Review Guidelines say that if your app supports account creation, it must also offer account deletion inside the app. Ask how they built it and what happens to the user's data on the backend.
• Login options. If an app uses a third-party login such as Google Sign-In for the primary account, the guidelines require an equivalent option that limits data collection to name and email and lets users keep their email private. Most teams meet this with Sign in with Apple. Ask when the rule applies and when it doesn't.
• Privacy disclosures. The App Store privacy "nutrition label", privacy manifests for the app and its third-party SDKs, and App Tracking Transparency prompts if the app tracks users for advertising.
• Build requirements. Apple's SDK minimum requirements say that since April 28, 2026, apps uploaded to App Store Connect must be built with Xcode 26 or later using the iOS 26 SDK. A good candidate knows this cycle repeats every year and plans for it.
• Rejections. "Tell me about your last rejection" is the single best question. Anyone who ships regularly has a story, and how they resolved it tells you a lot.

A paid iOS test task (and how to judge it)

Keep it to four to six hours, pay for it, and make it look like your real work. A short brief that works for most apps:

1. Build a SwiftUI app with a list loaded from a public API and a detail screen.
2. Use async/await for networking, with loading, empty and error states.
3. Cache the last response so the list works offline.
4. Support Dynamic Type and VoiceOver labels on the main screens.
5. Add unit tests for the data layer and one UI test.
6. Include a README explaining the architecture and what they'd do with more time.

Then review it against a simple pass/fail checklist:

• Does it build and run on the first try from a clean clone?
• Is networking and parsing separate from the views?
• Are errors handled, or does it only work on the happy path?
• Does it still look right with the largest text size?
• Do the tests check real logic?
• Is the README honest about trade-offs?

Finish with a 30-minute call where the candidate walks you through the code and makes one small change live. People who didn't write their submission struggle here.

iOS developer rates by region

These are typical market ranges for experienced iOS developers, not quotes. Rates vary with seniority, city and what is included, and they move every year.

Remember Apple's own fixed cost: the Apple Developer Program is a $99 annual membership. Enroll under your company, not the developer's name. For whole-project budgets, see our iOS app development cost breakdown.

Freelancer, dedicated developer or agency?

Match the model to what you already have in-house:

• You have an iOS lead and need extra hands: a freelancer or staff-augmentation developer works well. Your lead reviews the code.
• You have a product owner but no iOS lead, and an ongoing roadmap: a dedicated senior developer through a vendor, with the vendor covering replacement if they leave.
• You need a whole app shipped, including design, backend, QA and review: an agency team. You get several people who know the codebase, not one.
• You need iPhone and Android: consider Flutter before hiring two native teams. Our React Native vs Flutter guide covers when cross-platform makes sense and when native Swift is worth it.

Set up your Apple accounts before day one

Ownership problems with iOS apps almost always start with accounts. Before your developer writes a line of code:

• Enroll in the Apple Developer Program as an organization in your company's name. Organization enrollment asks for a D-U-N-S number, so start early.
• Invite developers through App Store Connect and your developer account with the role they need. Keep the Account Holder role yourself.
• Keep the code in your own Git organization, and certificates, provisioning and signing managed in a way you can access without the developer.
• Put push notification keys, StoreKit configuration and analytics accounts under company logins.

Red flags when you hire a Swift developer

• No live apps you can download, or vagueness about what they built in each one.
• "Review is just luck." Rejections happen, but experienced developers know why and design around them.
• No plan for the annual iOS release. Every September brings a new iOS version and, months later, a new upload requirement.
• Wants to publish under their own developer account. Your app should live in your account from the first TestFlight build.
• Tests only on the newest iPhone. Ask which older devices and iOS versions they test on.

Frequently asked questions

How much does it cost to hire an iOS developer?

Typical freelance rates run from about $18 to $45 an hour in India to $70 to $150 in the US, with agencies charging more because their rate covers QA, design and project management. These are typical ranges that vary with seniority and location. Add Apple's $99 annual developer membership, which your company should pay for directly.

What skills should an iOS developer have?

Strong Swift, including async/await and Swift 6 concurrency checks, SwiftUI with UIKit where needed, a testable architecture, networking and offline storage, and the Apple frameworks your app uses, such as StoreKit or push notifications. Just as important is release experience: TestFlight, signing, privacy disclosures and handling App Store rejections.

Should I hire a Swift developer or a Flutter developer?

Hire a Swift developer if your app is iPhone-first or depends on Apple features like widgets, HealthKit or Apple Watch. If you need iPhone and Android from the start and the app is mostly standard screens, a Flutter developer can cover both with one codebase. Decide the platform before you start interviewing.

How do I test an iOS developer before hiring?

Give a short paid task of four to six hours, such as a SwiftUI list and detail app with async networking, offline caching, accessibility support and tests. Check it builds from a clean clone and handles errors, then hold a short call where they explain the code and change something live.

Who should own the Apple Developer account?

Your company should. Enroll as an organization, keep the Account Holder role yourself, and invite developers with the roles they need. If a developer publishes your app under their personal account, moving it later is slow and disruptive, so set this up before the first TestFlight build.
