Hire Swift and iOS Developers in the UK

Native iOS developers who write modern Swift, know where SwiftUI still needs UIKit, and plan around App Store review instead of discovering it.

  • Senior engineers who ship production code
  • Hourly, dedicated or managed delivery
  • You interview before anyone starts

Swift and iOS expertise

Swift and iOS expertise our developers bring.

iOS engineers who know the current Apple frameworks as well as the UIKit and Objective-C code that established apps are built on.

SwiftUI and UIKit together

New screens in SwiftUI, UIKit where it is still the better tool, and clean bridges between the two — no rewrite needed to start using SwiftUI.

Sound app architecture

Views, state and services kept apart, Swift Concurrency with async/await and actors, and Swift 6 data-race checking enabled where the codebase allows.

App Store review readiness

In-app purchase rules, in-app account deletion, privacy labels and privacy manifests handled before submission, not after a rejection.

Apple frameworks

HealthKit, MapKit, Apple Pay, StoreKit, Sign in with Apple and Core ML, each with the permission prompts and privacy wording it needs.

Accessibility from the start

VoiceOver labels, Dynamic Type, strong contrast and reduced-motion support, checked with Accessibility Inspector and the settings real users switch on.

Widgets and notifications

WidgetKit widgets, Live Activities, time-sensitive notifications and App Intents for Siri and Shortcuts — the surfaces that bring people back.

What they build

What Swift and iOS developers can build for you.

Native iOS work for UK apps that need to feel at home on iPhone — or are too established to rewrite.

Health and wellbeing

HealthKit-connected apps

Read and write steps, workouts or sleep with the user’s permission, and handle it as the special category health data UK GDPR says it is.

Retail and hospitality

Apple Pay and Wallet

Tokenised Apple Pay checkout through your payment provider, plus Wallet passes for loyalty cards, tickets and vouchers.

Travel and logistics

Location and maps

MapKit routes, geofenced alerts and background location used sparingly, with battery life and Apple’s location rules in mind.

Public sector and charities

Accessible public-facing apps

Apps built toward WCAG 2.2 AA and the UK public sector accessibility regulations, with an accessibility statement drafted for your review.

Established apps

Objective-C to Swift

Migrate file by file through a bridging header, starting with the code that changes most, while the app keeps shipping updates.

Growing products

iPad, Apple Watch and widgets

Extend a successful iPhone app to iPad layouts, a watchOS companion or Home Screen widgets, sharing code through Swift packages.

Developer seniority

The right level for the work.

Every engagement is staffed with senior engineers. What changes is how much architecture and leadership the work needs around them.

Most engagements

Senior Swift and iOS developer

Takes features from ticket to reviewed, tested, deployed code without hand-holding. The right choice for most roadmap work.

New builds and rescues

Lead engineer or architect

Sets the Swift and iOS architecture, reviews the team's code and plans migrations, upgrades and scaling work.

Multi-discipline scopes

A small blended pod

A Swift and iOS developer with backend, QA or design support, coordinated by one delivery owner for larger scopes.

Engagement models

Ways to hire Swift and iOS developers.

Pay by the hour for bursts of work, reserve a dedicated developer for your roadmap, or hand us the whole project.

Hourly Swift and iOS developer

From £23 per hour

Backlog work, fixes, integrations, and flexible sprint support

Why Techsleight

Why hire through Techsleight.

What you can hold us to — and what happens if something is not working.

You choose who joins

You see profiles and talk to the Swift and iOS developer before anything starts, and nobody joins your team without your say-so.

Senior, production engineers

People who have shipped and supported real products — reviewed for code quality, testing habits and communication, not just a CV.

They work your way

Your repositories, tickets, stand-ups and review rules. Daily written updates and a weekly demo keep the work visible.

No lock-in

Hourly, dedicated or project-based, with short notice periods. Scale up for a launch and back down after it.

You own the code

Code, IP and documentation belong to you from day one. NDA before any detailed conversation, if you need one.

UK-focused delivery

UK business hours, GBP pricing and a contract with a UK company. Our engineers are based in the UK and India.

A whole team behind one hire

Backend, QA, DevOps and design colleagues are there when the Swift and iOS work needs them — without you hiring for each role.

FAQs

Questions we get asked.

Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.

Ask us a question

Native Swift or a cross-platform framework?

Go native when the app leans on Apple-only features — HealthKit, widgets, Apple Watch, advanced camera work or AR — or when most of your customers are on iPhone. If you need Android too on a tight budget, React Native or Flutter is often the better call, and we will tell you so.

Can you help our app get through App Store review?

We build with Apple’s review guidelines in mind from the first sprint: in-app purchase rules for digital goods, in-app account deletion, accurate privacy labels and a working demo account for the reviewer. If an app is rejected, we read the guideline cited, fix or respond in App Store Connect, and resubmit.

Should we rewrite our UIKit app in SwiftUI?

Not in one go. SwiftUI and UIKit work side by side, so we build new screens in SwiftUI and convert old ones when they need significant change anyway. Complex, performance-sensitive screens can stay in UIKit indefinitely without holding the rest of the app back.

How much does it cost to hire a Swift and iOS developer in the United Kingdom?

Swift and iOS developer rates at Techsleight Labs start from £23/hour for flexible work and from £3,300/month for dedicated monthly capacity. Fixed-price Swift and iOS projects are quoted after discovery, once scope, integrations, risks, and timeline are clear.

How quickly can a Swift and iOS developer start?

Most Swift and iOS engagements start within 5–7 working days of sign-off, and urgent work can sometimes start within 48–72 hours. For larger projects, we first confirm scope, architecture, milestones, and the right senior engineer fit before kickoff. We support UK teams with written updates, planned demos, and timezone-aware handover.

Can I hire one Swift and iOS developer or a full team?

Yes. You can hire a single Swift and iOS developer, add a small pod with QA and DevOps, or ask us to manage the complete project. We match the model to your current team, delivery pressure, and budget.

Are your Swift and iOS developers senior?

Yes. Our hiring pages are built around senior production engineers, not junior bench resources. Every developer is reviewed for commercial project experience, communication quality, code quality, testing habits, and ability to work inside existing teams.

Do you work with existing Swift and iOS codebases?

Yes. We often join existing Swift and iOS projects to fix performance, unblock releases, add features, improve test coverage, or modernise architecture. We start with a codebase review so the first sprint is practical rather than theoretical.

What happens if the Swift and iOS developer is not the right fit?

Tell us early. We will look at the cause with you — the brief, the onboarding or the match — and agree the next step together, such as more technical oversight, a different engagement model, or ending the engagement on the notice terms in your contract. The goal is a useful working relationship, not lock-in.

Will we own the Swift and iOS code and IP?

Yes. You own the code, documentation, infrastructure setup, and product IP created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project management tools.
