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.

Capabilities
Swift and iOS capabilities we bring to your product.
iOS engineers who know the current Apple frameworks as well as the UIKit and Objective-C code that established apps are built on.
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 we build
What we build with Swift and iOS.
Native iOS work for UK apps that need to feel at home on iPhone — or are too established to rewrite.
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.
Apple Pay and Wallet
Tokenised Apple Pay checkout through your payment provider, plus Wallet passes for loyalty cards, tickets and vouchers.
Location and maps
MapKit routes, geofenced alerts and background location used sparingly, with battery life and Apple’s location rules in mind.
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.
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.
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.

Pricing
Swift and iOS development pricing.
Start with discovery, move to a fixed-price build, or run a dedicated team for a longer roadmap.
Swift and iOS discovery sprint
From £2,000
Architecture, roadmap, cost planning, and project-risk validation
- A short strategy sprint covering technical scope, user flows, delivery plan, and budget range.
Managed Swift and iOS development project
Fixed quote
MVPs, rebuilds, SaaS platforms, dashboards, portals, and business-critical launches
- Product planning, UX, engineering, QA, deployment, and post-launch support under one delivery owner.
Dedicated Swift and iOS development team
From £9,500 per month
Longer roadmaps, multi-sprint delivery, and product teams that need extra senior capacity
- A stable engineering pod with weekly demos, sprint planning, code review, and transparent reporting.
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How we deliver
How we deliver your Swift and iOS project.
Seven stages, the same on every project. The length of each one changes with the work; skipping one never saves time for long.
- 01
Product and technical discovery
We map your Swift and iOS product goals, users, integrations, compliance needs, timeline, and commercial priorities before planning the build.
Goals, users and constraints agreed
- 02
Architecture and delivery plan
You get a practical Swift and iOS roadmap with milestones, team shape, risks, estimates, and the first release path.
Roadmap, team and estimate
- 03
Design, build, and QA
Our team ships the Swift and iOS product in controlled sprints with code review, testing, demos, and visible progress every week.
Tested software every sprint
- 04
Launch and improvement
We handle deployment, analytics, monitoring, handover, and post-launch iterations so your Swift and iOS platform keeps improving.
Live, monitored and documented
Why Techsleight
What working with us is actually like.
No inflated numbers — just how we run projects, and what you can hold us to.
Product engineering, not ticket-taking
We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.
AI where it earns its place
LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.
Full-stack under one roof
Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.
UK-focused delivery
UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.
Flexible engagement
A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.
You own everything
Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.
Support after launch
We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
What does a Swift and iOS development company do?
A Swift and iOS development company plans, designs, builds, tests, deploys, and supports Swift and iOS software. At Techsleight Labs, that can include discovery, architecture, UI/UX, API integration, QA, cloud deployment, analytics, and post-launch roadmap support.
Do you work with companies in the United Kingdom?
Yes. This Swift and iOS development company page is focused on United Kingdom businesses. We support UK collaboration with clear written updates, weekly demos, and planned handoff points so distributed teams can move quickly.
How much does Swift and iOS development cost?
Swift and iOS development pricing depends on scope, integrations, user roles, design depth, compliance needs, and launch timeline. Discovery sprints start from £2,000, dedicated teams start from £9,500/month, and managed projects are quoted after scope validation.
Can you build a complete Swift and iOS product, not just provide developers?
Yes. You can use Techsleight Labs as a full Swift and iOS development company for strategy, design, engineering, QA, deployment, and support. You can also start with a small discovery sprint before committing to the full build.
Can you improve an existing Swift and iOS application?
Yes. We often join existing Swift and iOS products to fix performance, improve architecture, add features, stabilise releases, modernise UI, or prepare the system for scale. We begin with a focused audit so the first sprint is practical.
Who owns the code and product IP?
You own the code, documentation, product IP, design assets, and infrastructure setup created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project tools.
How fast can a Swift and iOS development project start?
Discovery can usually begin within a few working days of the first call, and most projects start within 5–7 working days of sign-off. Larger builds usually need a short planning sprint to confirm scope, architecture, milestones, risks, and the right team before full development begins.
Do you provide post-launch Swift and iOS support?
Yes. After launch, we can continue with monitoring, bug fixes, performance improvements, security updates, roadmap features, analytics, and handover support. Many clients keep a monthly retainer after the main release.
