iOS App Development Services

Building an application for iOS means aiming high because Apple users don’t tolerate lag, clunky UX, or apps that crash the second they load. The iOS team at Devfan gets that. We design and develop iOS apps that are both clean under the hood and feel intuitive for users.

Whether your business needs to roll out a new iOS digital product, rebuild an underperforming app, or need a senior team to push your MVP across the finish line, Devfan’s Swift or Objective-C developers work fast and effectively. Our goal is to build high-performing, functional, native experiences for Apple users.

Our iOS Mobile App Development Services

Devfan is the leading provider of native iOS mobile app development services in the UK. We proudly cooperate with businesses of any size across industries, from startups to well-established enterprises. We offer full-stack iOS development services that align with your business goals.

iPhone App Development

If your iPhone app doesn’t load fast, feel native, and handle high user flow, you’re losing customers. Our Swift developers build iOS apps that pass App Store review and perform as expected across devices. Optimised for speed, tested for real-world friction, and designed to feel like they belong on the iPhone from day one.

iPad App Development

iPad apps aren’t just scaled-up phone screens: they’re a different experience altogether. And Devfan’s developers treat them that way. Whether you’re building an education platform, a dashboard-heavy finance app, or something more niche, we make sure it looks pixel-perfect, works clean, and takes full advantage of the iPad’s screen.

Apple Watch App Development

The wrist isn’t a second screen: it’s its own playground. Our iOS engineers build Apple Watch apps that do more than push notifications. We guarantee fast data sync, real-time actions, and simple interactions. If your app has value at a glance or with a tap, we’ll make it work on a device people use in motion.

Apple TV App Development

TV apps are a different digital experience: slower input, larger screens, passive users. We build Apple TV apps with that in mind. Whether you’re in media, fitness, education, or eCommerce, Devfan designs Apple TV apps that are smooth, responsive, and keep attention.

iOS Migration Service

Moving an app to iOS or upgrading a legacy Objective-C code shouldn’t break app functionality. Our senior developers handle full-stack iOS migrations with a focus on stability and performance. Code cleanup, redesigns, iOS version upgrades, you name it: we perform iOS migrations & updates without data loss, user confusion, or downtime.

iOS Support & Maintenance Service

Apps age. APIs change. Bugs sneak in. Devfan’s Swift developers keep your iOS app in shape long after launch. From performance tuning to OS updates, crash reports to UI tweaks, they track what matters, fix what breaks, and make sure your app stays fast, secure, and competitive.

Hire Dedicated iOS App Developers

Building for iOS is pure software engineering. And when you’re trying to deal with deadlines, App Store approvals, and version updates alone, the last thing you need is a failed software or broken code. Devfan connects you with experienced iOS developers who live and breathe native app development, writing clean, efficient code in Swift, and navigating legacy Objective-C projects without frustration.

Whether you’re just starting a new iOS mobile application development project, migrating from legacy code, or scaling an in-house team that’s missing Swift or Objective-C expertise, Devfan makes it easy to bring real iOS expertise into your workflow.

Benefits of Hiring iOS Developers at Devfan

You’re not handed a resume pile

You get pre-vetted, on-staff developers with real iOS experience, from multi-module Swift apps to hybrid projects still running on Objective-C. We make sure they’re a fit before they land in your Slack.

We handle the onboarding curve

No time lost on figuring out access or how your dev environment works. We work with you to get your new team members set up, aligned, and shipping code without stalling the rest of your roadmap.

Remote-ready, not remote-optional

Our devs are set up with all the necessary equipment to work remotely. They’re part of a larger team that shares standards, reviews code, and stays sharp together.

Scale up or down easily

Need two devs now and three more in a month? Need to pause the project mid-sprint? You scale your team when it makes sense and we’ll handle the logistics behind it.

Clear communication

Strong English, consistent updates, and an understanding of how to work inside cross-functional teams. Our devs don’t disappear after the standup or send vague commits you have to double-check.

We invest in their skills so you don’t have to

Swift updates. iOS SDK changes. New libraries and system APIs. Our team stays current, because it’s built into how we work.

If someone’s not the right fit, we swap fast

If you feel an iOS developer isn’t working out, we’ll bring in someone else before the project slips.

FAQ

Frequently Asked Questions - iOS App Development Agency in the UK

❓ What tech stack do you use for iOS app development?

We build native iOS apps using Swift, Apple’s current standard. Our iOS developers are also fluent in Objective-C for legacy systems or projects that still rely on older codebases. We work with Xcode, UIKit, SwiftUI, Core Data, Combine, and integrate third-party SDKs when needed. If your app spans Swift and Objective-C, Devfan can handle both without turning it into a migration nightmare.

❓ Can you take over an app built in Objective-C?

Yes, and we’ve done it plenty of times. Some of the apps we maintain and extend today started over a decade ago. We’ll assess the current codebase, flag problem areas, and either keep it stable or gradually migrate the logic to Swift without disrupting users or breaking core functionality.

❓ Do you support apps after launch?

Yes. Devfan provides bug fixes, OS updates, feature additions, performance checks, crash log reviews. We stay involved for the long run, especially as Apple rolls out new devices, Swift versions, and breaking SDK changes. Check out our software support & maintenance packages.

❓ Can I hire just one iOS developer to extend my team?

Yes. Whether you’re a startup with one in-house dev or an enterprise team looking to move faster, we can embed a dedicated Swift/Objective-C engineer into your team. They’ll use your tools, follow your workflow, and contribute like they’ve been there from day one.

❓ What’s your approach to SwiftUI vs UIKit?

We use SwiftUI where it makes sense: mainly in greenfield projects or isolated views that benefit from a reactive UI approach. But UIKit still makes more sense in many production apps, especially when you’re dealing with more complex, battle-tested UI needs.

To cut the long story short, Devfan engineers use what works best for your product.

❓ Can you handle App Store submission and compliance?

Yes, our iOS devs know how to navigate App Store quirks, rejection reasons, entitlement settings, privacy policies, and more. We’ll walk your app through every requirement, from signing to release, so you’re not stuck decoding Apple’s documentation on your own.

❓ How do you ensure quality and stability?

Code reviews, unit testing, crash monitoring (via tools like Crashlytics or Sentry), performance profiling, and regression testing: every app we ship goes through real testing, not just “looks fine on my device.” We make sure your app runs fast, responds smoothly, and doesn’t fall apart after the next iOS update.
