We build native iOS apps in Swift and SwiftUI that feel at home on Apple devices: fast, private, accessible and ready for App Store review. From first prototype to launch and every iOS update after.
iPhone users are used to smooth animation, strong privacy and apps that follow Apple's design language. Native iOS development in Swift gives your app full access to the latest iOS features on day one, from widgets and Live Activities to Apple Pay, Face ID and HealthKit.
Our iOS team designs to Apple's Human Interface Guidelines, writes modern Swift and SwiftUI code, and prepares your app for App Store review with clear privacy labels and permission flows. That means fewer rejections, faster approval and better ratings.
Native code for smooth scrolling, animation and fast start-up.
Keychain, secure enclave, App Tracking Transparency done right.
Human Interface Guidelines, Dynamic Type and Dark Mode.
iPad, Apple Watch, widgets and Siri Shortcuts.
Everything from a new iPhone app to modernising an existing one.
New native apps in Swift and SwiftUI, designed around your users and business goals.
Layouts that make full use of larger screens, multitasking and Apple Pencil.
watchOS companions, Home Screen widgets and Live Activities.

Move Objective-C or UIKit apps to modern Swift and SwiftUI.
From iPhone to Apple Watch, we design and build apps that follow Apple's Human Interface Guidelines and pass App Review smoothly.
We build with SwiftUI for modern interfaces and UIKit where needed, with layouts that adapt from iPhone SE to iPad Pro, plus support for Dark Mode, Dynamic Type and accessibility.
Watch apps work best for quick actions: workouts, health data, reminders and notifications. We build watchOS apps that sync with iPhone and HealthKit.
We use Apple's native frameworks to build features that would be hard elsewhere: on-device ML, AR product previews, document scanning, NFC and Bluetooth devices.
We modernise Objective-C or old Swift apps, adopt new iOS releases and manage the full App Store process, including privacy labels and review responses.
Native iOS is the right choice when experience and performance matter most.
Apps for audiences where iPhone users are a large and high-value share of your market.
Workout, wellness and patient apps that connect to Apple Health and Apple Watch.
Secure finance apps that use Face ID, Keychain and Apple Pay.

New Apple features arrive in SwiftUI first, so most new screens are built in SwiftUI.
Delivery, rides, sports and bookings use the Lock Screen and Dynamic Island for live updates.
More apps replace passwords with passkeys synced through iCloud Keychain.
Apple requires apps and SDKs to declare data use, so SDK choices matter more than before.
Strict concurrency checking helps prevent crashes and data race bugs in complex apps.
iPhone has a strong share of the smartphone market in the USA, UK, Australia, New Zealand and the Gulf, which makes native iOS a smart first platform in those markets.

"What impressed us most about UD3 Logic was their ability to understand the healthcare industry rather than treating the project like a standard software development assignment. They invested time in learning how our hospital operates, the challenges faced by our staff, and the expectations of our patients before proposing solutions. This resulted in a platform that felt practical and intuitive instead of being overloaded with unnecessary features.
Another standout quality was their willingness to collaborate. They welcomed feedback throughout the project, refined features based on our evolving requirements, and consistently focused on finding the best long-term solution instead of the quickest fix. Their technical expertise, combined with clear communication and genuine commitment to our success, made the entire engagement feel like a true partnership.
Even after the primary development work was completed, they continued to provide valuable support and enhancements, which gave us confidence that the solution would continue to evolve alongside our organization."

Detailed answers to the questions clients ask us most before starting a iOS App Development project.
Talk to a project lead. We usually reply within one working day.
Ask a questionNative iOS is the best choice when you need the smoothest performance, the latest Apple features on day one (widgets, Live Activities, Apple Watch, ARKit), or a premium feel for an audience that is mostly on iPhone. If you need Android too and your app is mostly standard business features, cross-platform may give better value; we will advise honestly.
New apps are built in Swift, usually with SwiftUI. We also maintain and migrate older Objective-C and UIKit apps to modern Swift, step by step, so the app keeps working during the move.
We follow Apple's App Store Review Guidelines from the design stage:
This keeps rejections rare, and if feedback comes back, we fix it quickly.
Yes. The app should be published under your own Apple Developer Program account (individual or organisation), so you keep full ownership. We help you set it up and manage certificates, profiles and TestFlight.
Yes. We can build a universal app that adapts to iPad, and add Apple Watch companions, widgets and Live Activities where they add real value to your users.
A focused iPhone MVP usually takes 8–12 weeks. A full-featured app with payments and custom design takes about 3–5 months. Apps that span iPhone, iPad and Apple Watch take longer. You get an exact plan after discovery.
Yes. We implement StoreKit 2 for subscriptions, consumables and one-time purchases, including free trials, receipt validation on the server and restore-purchase flows.
Yes. Apple releases a major iOS version every year. Our maintenance plans test your app on beta versions, update it for new APIs and devices, and keep it compliant with new App Store rules.
We use SwiftUI for most new screens because it's faster to build and supports the newest Apple features. We still use UIKit for complex custom components or when extending older apps.
Yes. We use Apple Business Manager custom apps or your MDM, so the app is available only to your organisation.
Yes. We build Home Screen and Lock Screen widgets, Live Activities and Dynamic Island experiences for real-time updates such as deliveries and bookings.
Yes. We add Sign in with Apple, passkeys stored in iCloud Keychain and Face ID login, which make sign-in faster and reduce password resets.
