iOS development services built for Swift 6 and iOS 26
Apple’s annual SDK requirement, Liquid Glass UI, and on-device Apple Intelligence have all landed in the last year — and they all affect how a serious iOS app gets built today. We build and modernize native iOS apps with Swift and SwiftUI, kept current with what Apple actually requires — headquartered in London with a world-class engineering team in India, delivering for clients across the UK, US, Europe, and Asia for over a decade.
What we build
iOS solutions we deliver.
From SwiftUI interfaces to Apple Intelligence features — native iOS engineering kept current with what Apple actually requires, not what shipped last year.
Expert Team & Proven Experience
10+ years in the industry, with 500+ happy clients worldwide.
Native iOS Apps with SwiftUI & UIKit
We build bespoke, high-performance iOS apps using SwiftUI’s declarative syntax where it speeds delivery, and UIKit where precise control over custom animations and layout is still the right call — and we’ll tell you which one fits before we start.
Apple Intelligence & On-Device AI Features
With iOS 26’s Foundation Models framework, on-device AI features — summarization, smart suggestions, content generation — can run without sending user data to a server. We integrate these capabilities where they genuinely improve the product.
Liquid Glass-Ready UI Modernization
iOS 26 brought the biggest visual overhaul to Apple’s platforms in years. We update existing app interfaces to feel native under Liquid Glass without breaking compatibility for users still on earlier iOS versions.
Offline-First Apps with Core Data & Realm
For apps that need to work reliably without a constant connection, we build offline-first data layers with Core Data or Realm, with sync strategies that resolve conflicts cleanly when connectivity returns.
App Store Submission, Compliance & SDK Migration
Since April 2026, Apple rejects any submission not built on the iOS 26 SDK. We handle SDK migrations, deprecated API cleanup, and the submission process itself, so an outdated build target doesn’t block your release.
Legacy iOS Modernization
For apps still running older UIKit patterns or pre-Swift 6 concurrency, we modernize incrementally — adopting structured concurrency and SwiftUI piece by piece rather than forcing a ground-up rewrite.
Our approach
A decade of native iOS delivery, led from the UK
Building and shipping complex native iOS applications since 2013, across 500+ clients in the UK, US, Europe, Japan, the Middle East, and Asia — we’ve already solved most of the classic iOS production problems before they cost you time and money. Our London team manages everything client-facing, from discovery through delivery sign-off, while our engineering team in India handles the deep technical build: senior oversight without the cost of a fully Western dev team. iOS sits alongside Android, Flutter, Ionic, and React Native as one of five core mobile stacks we actively maintain client apps on across our published case studies — see our native Android and cross-platform mobile development practices if your product needs either.

Architecture & compliance
SwiftUI or UIKit, built on infrastructure you can trust
SwiftUI for speed and modern, declarative interfaces. UIKit where you need fine-grained control or are maintaining an existing codebase — we tell you which fits before we start building, not which one we prefer. App Store guideline compliance, data privacy disclosures, and secure authentication are designed in from the first architecture decision, not patched in right before submission, and the backend behind your app is built by an AWS and Microsoft Azure certified partner, giving direct platform support and deep cloud expertise on every deployment.

Our process
From first call to App Store launch
We start with 1–2 weeks of discovery and architecture planning — mapping your requirements, choosing SwiftUI, UIKit, or a mix, and deciding on the data layer, Core Data or Realm, before any code is written — followed by 1–3 weeks of design and prototyping in Figma, refined through real user feedback before development begins. Development runs in continuous, sprint-based cycles with CI/CD via Fastlane or Xcode Cloud and weekly progress reports, and every launch is followed by 90 days of active support: App Store submission, crash and performance monitoring, and tuning based on real usage.

FAQ
Frequently asked questions
What we hear most often about iOS projects — SDK requirements, framework choice, and what happens after launch.
What kinds of iOS projects do you take on?
Native iOS apps, on-device AI features, UI modernization for Liquid Glass, offline-first apps, App Store compliance and SDK migrations, and legacy iOS modernization. Our experience spans retail, healthcare, hospitality, and service-based businesses.
SwiftUI or UIKit — which will you use for our app?
It depends on your app and timeline. SwiftUI for modern, fast-to-build interfaces. UIKit when you need fine-grained control or are extending an existing UIKit codebase. We’ll tell you which fits after understanding your requirements.
Is our existing app affected by the iOS 26 SDK requirement?
If you haven’t submitted a build using the iOS 26 SDK since April 2026, yes — any new submission or update will be rejected until you migrate. This doesn’t force you to drop support for older iOS versions on users’ devices; it’s about which SDK you build with.
Can you add Apple Intelligence or on-device AI features to our app?
Yes. Using iOS 26’s Foundation Models framework, we can add on-device summarization, smart suggestions, and content generation without sending user data off-device — where it genuinely improves the product, not as a checkbox feature.
Can you take over an existing iOS codebase?
Yes. We regularly take over existing Swift and Objective-C codebases — auditing for deprecated APIs, outdated dependencies, and SDK compliance gaps before planning any modernization work.
What happens after the app is launched?
We include 90 days of post-launch support covering crash monitoring, bug fixes, and performance tuning. After that, we offer optional retainers for feature development and staying current with Apple’s annual SDK updates.
Ready to ship an iOS app built for 26 and beyond?
Whether you’re starting fresh or your existing app needs an SDK migration before your next submission, start with a conversation. We’ll tell you what’s feasible, what it will take, and what’s actually required.
