Hire iOS developers

An iOS app lives or dies on details users never name but always feel: launch time, scroll smoothness, how it behaves offline, whether it survives the next OS update. Plenty of developers can follow a SwiftUI tutorial. Far fewer can architect an app that stays fast at scale, pass App Store review on the first try, and debug a crash that only happens on older devices. turnkey.dev vets for the second group.

What an iOS developer does for you

A strong iOS hire will:

• Build in modern Swift with the right UI framework for your app. SwiftUI for new work, UIKit where maturity or fine control matters, and clean interop when a codebase needs both.
• Structure the app to survive change. Clear separation of views, state, and services, so the third redesign is not a rewrite and new features do not break old ones.
• Handle data and networking properly. Core Data or SwiftData for local persistence, resilient API clients, and sane behavior when the connection drops mid-action.
• Own the release pipeline. Signing, TestFlight, phased rollouts, and App Store review, including the guideline landmines around purchases, permissions, and privacy labels.
• Ship the revenue and retention plumbing: push notifications that arrive, in-app purchases and subscriptions that restore correctly, and deep links that land users where you promised.
• Keep the app fast and accessible. Instruments-driven performance work, crash triage, and VoiceOver and Dynamic Type support that widens your audience and helps in review.

When to hire an iOS developer

The common triggers: you are building a native app for the first time and want it right from the start, an agency-built app needs a long term owner, your app is drowning in crash reports or App Store rejections, or a new OS release broke things and nobody in-house knows the platform. If you need iPhone and Android from one codebase and native depth is not the constraint, the React Native and Flutter hubs below may fit better, and many developers in our pool work across them.

How turnkey.dev vetting works

Every developer goes through a screen on Swift and platform fundamentals (memory management, concurrency, the view lifecycle), a practical exercise built around a realistic feature with a debugging twist, and a review of apps they have shipped, including scale, review history, and what broke in production. A portfolio of published apps is expected, not optional. We reject far more than we accept.

Seniority, and what each level is for

Most companies coming to us need one senior developer who can own the app outright, with a lead brought in briefly for decisions like a SwiftUI migration plan or a subscription model overhaul.

What it costs and how fast

Vetted iOS developers typically bill in the $70 to $130 per hour range, with architecture-level engineers and in-app purchase specialists at the top. That is usually well below the loaded cost of a full time hire, without the months of recruiting. You will see the rate before committing, and requesting a shortlist is free. Expect a shortlist in 2 to 5 days.

Start with a request, not a contract

Tell us about the app (new build, rescue, or ongoing ownership), the stack it uses today, and your timeline. We come back with a short list of vetted developers who fit, including rate and availability. You interview, run a paid trial if you want, and only then decide. If the fit is wrong in the first two weeks, we re-match at no cost.
