Hire iOS Developers Who Ship Through App Review, Not Just to Simulator
Northell places iOS developers who own a build all the way through App Store review — not just until it runs in the simulator. Every developer is screened on offline state, background execution, and a real signed build, because that is where iOS projects actually stall.
Scope the role
Tell us the product, the stage, and the specific gap — a one-off build, an ongoing developer, or a whole squad.
Meet 2-3 matched developers
Shortlisted from our own vetted bench, not a marketplace of unverified profiles.
Start the engagement
Full-time embedded, part-time, or contract-to-hire — begin with a paid trial week before any longer commitment.

Northell places iOS developers on product teams that need a native app shipped and kept alive through Apple's release cycle. The bench behind this page has shipped 155+ product builds and holds a Clutch Top 20 ranking for Product Designers and Developers. iOS candidates are screened on offline-tolerant state, background execution, and an actual signed build submitted through review — because a simulator demo hides nearly everything that makes iOS work hard. Engagements run full-time embedded, part-time, or contract-to-hire, and every one opens with a paid trial week.
- Swift and SwiftUI, with the UIKit fluency any real codebase still requires.
- Screened on offline state, background work, and a genuine signed store build.
- Owns submission, privacy manifests, and turning around review rejections.
- Every engagement opens with a paid trial week before any longer commitment.
iOS Profiles Available Now
Senior iOS Engineer — SwiftUI Consumer Apps
Owns a consumer app end to end, from first screen through store release and the iterations after it.
What you'll build
SwiftUI surfaces with sensible navigation and state, push notifications, widgets, and a release pipeline that makes shipping an update routine rather than an event.
Often the only iOS engineer on a small product team.
Why clients choose this profile
Comfortable owning the whole iOS surface and defending trade-offs directly to a founder.
Apply to get matched →Senior iOS Engineer — Secure Financial Apps
Builds banking and wallet flows where secure storage and offline transaction state are launch blockers.
What you'll build
Biometric authentication, Keychain-backed secure storage, certificate pinning, and transaction flows that behave correctly when the network drops mid-payment.
Embeds with product plus the backend engineer who owns the payments API.
Why clients choose this profile
Has shipped regulated mobile finance and treats secure storage and offline edge cases as blockers, not follow-ups.
Apply to get matched →iOS Engineer — HealthKit & Wearables
Integrates HealthKit, Apple Watch, and background sync into consumer health products.
What you'll build
HealthKit read and write flows, a companion watchOS app, background delivery that survives the OS suspending it, and permission flows that respect Apple's privacy rules from the first build.
Works with product plus whoever owns the data and backend layer.
Why clients choose this profile
Has shipped against HealthKit and watchOS before, where Apple's privacy and background rules cause most of the delays.
Apply to get matched →iOS Engineer — Objective-C to Swift Migration
Moves a long-lived Objective-C app onto Swift incrementally, without pausing feature work.
What you'll build
Swift and Objective-C interoperability, module-by-module migration, tests added around the parts about to change, and a dependency and toolchain update that unblocks current Xcode versions.
Usually joins a small internal team that owns the domain but lacks migration experience.
Why clients choose this profile
Pragmatic about what to migrate and what to leave alone, which is what keeps this kind of project funded to completion.

We don't publish a blended average rate — a single number hides more than it reveals across seniority, specialization, and region. The ranges above are placeholders until we've tracked enough engagements to publish real medians; ask for current numbers on a scoping call rather than trusting a guess here.
We Turn Most Applicants Away
What we screen for
- A live technical exercise on a real, timeboxed problem — not a take-home someone else could have finished.
- At least one shipped production system they can walk through and explain their own decisions on.
- A code-review / architecture-critique session — how they handle pushback, not just how they present.
- Depth in one stack we place for over shallow 'full-stack everything' claims across a dozen technologies.
- Direct, unassisted communication in a live call — no relay through an account manager during screening.
What we don't do
- We don't forward a resume because it has the right keywords.
- We don't run a single unstructured chat and call it vetted.
- We don't place an engineer we haven't personally worked with or verified.
- We don't quote a rate before we understand the actual scope.
We turn away most applicants before they ever reach a client introduction — we're not publishing an exact rejection rate here until we're tracking it well enough to stand behind the number.
How We Screen Every iOS Developer
Shipped-work + code review
We check for finished, production systems they've actually shipped — not just tutorial repos or slide decks.
Live technical exercise
A real, timeboxed problem drawn from a past Northell engagement, reviewed by one of our senior engineers.
Culture + communication check
A working session with the actual team they'd join, not only with Northell staff.
Who we're looking for
- Mid-to-staff level, with a track record of shipping production software (exact minimum years: TODO)
- Can walk through at least one system they took from scratch to production
- Comfortable presenting and defending technical decisions live
- Fluent in the core stack for the role, plus its testing and tooling ecosystem
- Experience owning code through code review, deploy, and on-call — not just writing it
- Written and spoken English fluency for client-facing work
- Available for a paid trial week before a longer engagement
- Comfortable working inside an existing codebase, not only greenfield builds
- Reads and writes tests as a default, not as an afterthought
- No conflicting concurrent full-time engagement, for embedded roles
- References from at least one prior client or employer we can verify directly
How it works
- You describe the role — Northell doesn't ask you to write a job post.
- We shortlist from engineers already vetted, not job-board applicants.
- You interview 2-3 matched profiles, not twenty.
- The engineer starts on a paid trial week before any longer commitment.
Common Hesitations, Answered Directly
What if the hire isn't a fit after we start?
That's what the paid trial week is for — flag it during the trial and we requalify or replace the person before any longer commitment is on the table.
What if we need someone full-time, not part-time?
Any engagement can convert from part-time or contract-to-hire into a full-time embedded model without restarting the vetting process — it's a scope conversation, not a new search.
What if our team is fully remote across time zones?
We match for meaningful working-hours overlap during scoping, not just calendar availability on paper.
What if we're not ready to commit long-term?
Start with the paid trial week. It exists specifically so neither side commits before actually working together.

Common Questions
SwiftUI or UIKit — which do the developers you place use?
Both, and the honest answer is that most production apps are a mix. SwiftUI is the default for new surfaces; UIKit still owns a lot of existing screens and some complex interactions. A developer who can only work in one of the two will hit a wall in almost any real codebase, so we screen for both.
Do they handle App Store submission and review rejections?
Yes — signing, provisioning, privacy manifests, store metadata, and the back-and-forth when review rejects a build. Getting rejected is routine; the useful skill is reading the rejection accurately and turning it around quickly, which is part of what we screen on.
Should we build native iOS or use React Native?
If your app depends on platform-specific capability — advanced camera work, ARKit, tight widget and Live Activity integration, or heavy on-device processing — native is usually the right call. If you are shipping the same feature set to iOS and Android with a small team, cross-platform often wins on cost. We will tell you which side of that line you are on during scoping, including when the answer means a smaller engagement for us.
Can they modernize an old Objective-C codebase?
Yes, and it is a specific skill we screen for separately. The work is incremental — bridging Swift into an existing Objective-C target, migrating module by module, and keeping the app shippable throughout — rather than a rewrite, which almost never gets funded to completion.
How fast can an iOS developer start?
Typically 1-2 weeks from the scoping call, and every engagement opens with a paid trial week. Exact turnaround depends on how specific the requirement is (precise day-count: TODO, not yet tracked).
Also Hiring
The State of iOS Hiring in 2026
The Simulator Hides Everything That Makes iOS Hard
An app that works perfectly on a development machine tells you very little. The hard parts are on a real device with a flaky connection: state that has to survive being backgrounded and terminated, background execution the OS is actively trying to limit, and memory pressure. Our live exercise targets those specifically, because a developer who has only built happy-path screens looks identical to a strong one right up until an app is running on a real user's phone.
Shipping Through App Review Is a Skill in Itself
Getting rejected by App Review is routine, and it is not usually a sign of bad engineering. What separates experienced iOS developers is how quickly they read a rejection accurately and turn it around — privacy manifest issues, background mode justifications, and account-deletion requirements are all common, all well documented, and all avoidable. A developer who has never taken an app through submission will learn this on your timeline instead.
Native or Cross-Platform, Answered Honestly
Native iOS earns its cost when the product depends on platform capability — advanced camera pipelines, ARKit, tight widget and Live Activity integration, or serious on-device processing. It is harder to justify when you are shipping the same feature set to both platforms with a small team, where a single cross-platform codebase usually wins on budget and iteration speed. We tell teams which side of that line they are on during scoping, including when the honest answer points to a smaller engagement for us.
Objective-C Migration Is a Sequencing Problem
Plenty of profitable apps still run substantial Objective-C, and the rewrite that would replace it almost never gets funded to completion. The developers who succeed here migrate module by module, keep the app shippable the whole way through, and add tests around the code immediately before changing it. It is a distinct skill from greenfield Swift work, and we screen for it separately rather than assuming any Swift developer can do it.
What Is Changing in iOS Hiring for 2026
SwiftUI has become the default for new work while UIKit remains unavoidable in existing codebases, so fluency in both is now the practical baseline rather than a bonus. Apple's privacy requirements — manifests, tracking disclosures, and data-handling declarations — have also moved from paperwork into engineering work that affects architecture. The other shift is trial-first hiring, with teams starting on a paid trial week rather than committing to a full-time mobile headcount upfront, which is how every engagement here opens.
The company-wide numbers on this page come from Northell's own delivered work: 155+ product builds shipped, a Clutch Top 20 ranking for Product Designers & Developers, a Manifest Top 4 Product Design Team distinction, and named client engagements including MeetAlfred, Referrizer, NWCC, SmartJen, and Finixflo. We have not yet published a large-sample rate or engagement-tenure dataset — every field marked TODO on this page is a placeholder awaiting that tracking, not an estimate dressed up as fact.
