Hire iOS Native App Experts

Hire Expert iOS Developers

Your app has to feel at home on an iPhone, get through App Review, and keep working after each iOS release. We place an iOS developer for an existing Swift app or a new one. Native is not always the answer: our published iOS apps use React Native or wrapped web apps, and we will say which suits you.

On the App Store already
The owner app for our wearable QR product reached it in three months
SwiftUI and UIKit
New screens in SwiftUI; older ones left in UIKit until there is a reason
Native or not, argued honestly
We build all three ways, so the advice does not depend on one skill

What an iOS developer looks after

Apple changes the ground every year: new OS versions, new review rules, new privacy requirements. The job is as much keeping an app acceptable to Apple as adding screens to it.

Chooses between SwiftUI and UIKit, screen by screen

SwiftUI is quicker for most new screens. UIKit still earns its place in heavy lists and older code. Swift and Objective-C can share a project, so an old app can move a file at a time as it changes.

Uses the device properly

Credentials in the Keychain, background tasks that respect Apple's limits, push and deep links, offline storage, and Instruments to find the memory leak or dropped frames a simulator never shows.

Deals with App Review

TestFlight builds, privacy declarations, review notes with a test login, and in-app purchase through StoreKit where Apple's rules require it. A good developer spots a likely rejection during the design stage.

How to judge an iOS developer in one call

  • Ask about the last App Review rejection they handled, and how they resolved it
  • Ask when they would still reach for UIKit in a new app
  • Ask how they keep the interface responsive using Swift concurrency
  • Ask how they would find a retain cycle, and to name the tool
  • If you need deep native work, test Swift directly. Our published iOS work is cross-platform, so judge the person, not the portfolio

Choose your developer level

Compare iOS developer levels, experience, and monthly rates (160 h per month, retainer discount; USD, invoiced in USD, GBP, EUR or INR). Every level is available on hourly, monthly, or dedicated-team engagements; short pieces of work are from $20/h.

How a iOS engagement runs

Your developer is part of our engineering team in India with 3โ€“5 hours of overlap with the UK and Europe; US calls by appointment.

Native, cross-platform or wrapped?

Native suits heavy device use, like camera work or HealthKit. If you also need Android and the app is mostly forms and lists, React Native is usually cheaper. We tell you our view before you commit.

What to send us

The Swift and minimum iOS versions, SwiftUI or UIKit, the backend, and anything Apple has rejected. After a call we confirm who is available and a start date.

Your Apple account

We recommend the Apple Developer account stays in your company's name, with access given to the developer. Set it up early, since enrolment can take time.

Between releases

A stable app rarely fills 160 hours a month. Yearly OS checks and small changes can be billed hourly, with a monthly developer when there is a real roadmap.

Frequently Asked Questions

Common questions about hiring iOS developers from itmarkerz.

SwiftUI or UIKit for our app?
SwiftUI for new screens where it does the job, and UIKit where an app already depends on it. Our published iOS work is React Native and wrapped web apps, so test native Swift depth at interview if you need it.
Can you migrate from Objective-C to Swift?
Yes, a file at a time, because Swift and Objective-C can live in one project. We usually convert code as it is being changed rather than stopping features to rewrite it all.
How do you handle App Store submissions?
We prepare the build, metadata and review notes, and answer Apple's review feedback. The wearable QR owner app reached the App Store this way. We recommend the Apple Developer account stays in your company's name.
Do you implement in-app purchases and subscriptions?
Yes, through StoreKit where Apple's rules need it. Digital goods generally have to use Apple's payment system, and the rules differ by region, so check the current guidelines against your business model first.

Tell us what the app must do on the phone

Device features, who uses it, and whether Android matters too. That decides native or not. We reply within one business day (IST) with our honest view of the options.
