Native iPhone and iPad apps, written in Swift

We design and build native iOS apps in Swift and SwiftUI that feel at home on iPhone and iPad, use the hardware properly and pass App Store review without drama.

Overview

Building for Apple’s platforms properly

Apple users expect apps to behave like Apple apps: familiar navigation, smooth scrolling, support for Dark Mode and Dynamic Type, Face ID sign-in and quick access through widgets. Meeting those expectations is easiest with native Swift and SwiftUI, which give direct access to every framework Apple releases, often on the day it ships, without waiting for a cross-platform layer to catch up.

Key decisions include which iOS versions to support, since newer SwiftUI features need recent releases; whether iPad, Apple Watch or Mac are in scope; how data syncs, whether through CloudKit or your own backend; and how you will charge, because digital goods sold in-app usually go through Apple’s in-app purchase system. Each choice affects design, testing effort and review. Each one deserves a deliberate answer.

A well-built iOS app launches quickly, respects privacy prompts and accessibility settings, handles poor connections gracefully, passes App Review without drama, and ships updates through an automated pipeline rather than one person’s laptop. It also uses Apple’s tooling well: Xcode Cloud or Fastlane for builds, TestFlight for beta feedback and phased releases to limit risk, so each update reaches users in a controlled way.

Who it’s for

Built for teams like yours

  • 01

    Products with iPhone-heavy users

    Businesses whose customers mainly use iPhones, such as many premium consumer brands, where a polished native experience reflects directly on how the brand is perceived.

  • 02

    Apps needing deep device access

    Products relying on HealthKit, ARKit, Core ML, Bluetooth accessories, Apple Pay or background tasks, where native code gives the most reliable access to these frameworks.

  • 03

    Apple ecosystem builders

    Companies that want widgets, Live Activities, Apple Watch companions or Siri shortcuts alongside the main app, built consistently in one Swift codebase. These extensions share data and code with the main app safely.

Why it matters

Why go native on Apple platforms

iPhone users notice when an app ignores the platform: odd navigation, laggy scrolling, missing Face ID or widgets. Building natively in Swift gives you direct access to Apple frameworks on release day, smoother animation, better battery behavior and an interface that follows Human Interface Guidelines, so your app feels like it belongs on the device.

We handle the parts that trip teams up — signing certificates, provisioning profiles, privacy manifests and App Store review notes — and everything lives in your own Apple Developer account.

Every engagement includes

  • Discovery & scopingwe define users, core flows and the iOS versions and devices you need to support.
  • Interface designiOS-native layouts and clickable prototypes you can try on a real phone before development.
  • Swift developmentapp code, local storage and API connections built and reviewed together.
  • Device testingchecks across iPhone and iPad sizes, OS versions, accessibility settings and network conditions.
  • App Store submissionlisting, screenshots guidance, privacy labels and review handling in your own account.
  • Handoversource code, documentation and build instructions, plus an optional care plan for OS updates.

Features

What we build for iOS

  1. 01

    SwiftUI interfaces

    Declarative SwiftUI screens, with UIKit where it still fits better, that adapt cleanly to every iPhone and iPad size.

  2. 02

    Device capabilities

    Camera, Core Location, HealthKit, Bluetooth and NFC integrations wired in with the right permission prompts and fallbacks.

  3. 03

    Sign in and payments

    Sign in with Apple, Face ID unlock, Apple Pay and StoreKit subscriptions implemented to Apple’s current rules.

  4. 04

    Offline-ready data

    SwiftData or Core Data storage with background sync, so the app stays useful on weak or missing connections.

  5. 05

    Widgets and extensions

    Home Screen widgets, Live Activities, share extensions and push notifications that keep users engaged outside the app.

  6. 06

    Release pipeline

    Automated builds, TestFlight distribution and App Store Connect setup so every release follows a repeatable, documented path.

In practice

Typical iOS projects

  • Consumer subscription apps

    Fitness, education and media apps sell access through StoreKit subscriptions, with free trials, restore purchases, family sharing and paywalls that follow Apple’s review guidelines. Receipt validation and subscription status are handled server side, so access stays accurate across devices.

  • Health and wellness tracking

    Apps read and write HealthKit data with the user’s permission, sync with Apple Watch and present trends clearly, built to the privacy requirements the client sets with their advisers. Users stay in control of what they share.

  • Augmented reality experiences

    Retailers and educators use ARKit and RealityKit to place products in a room, guide physical tasks or visualize spaces, with fallbacks for devices that lack the required sensors. Performance is tuned so scenes stay stable and responsive.

  • Rebuilding older Objective-C apps

    Apps written years ago in Objective-C or UIKit are migrated screen by screen to Swift and SwiftUI, keeping the app live while the codebase becomes easier to maintain. Existing users keep their data throughout the migration.

Process

How we work

  1. 1

    Platform scoping

    We decide supported iOS versions, devices, Apple frameworks, payment model and backend needs, and check plans against App Store guidelines early to avoid review surprises later. Decisions are written into a short platform brief that guides design and development.

  2. 2

    HIG-based design

    Screens are designed in Figma following Apple’s Human Interface Guidelines, covering Dark Mode, Dynamic Type, and iPhone and iPad layouts, then prototyped on device for feedback. Accessibility is considered from the first screen rather than added at the end.

  3. 3

    SwiftUI development

    We build in Swift and SwiftUI with a clear architecture, unit and UI tests, and continuous builds, delivering test versions through TestFlight at the end of each development cycle. Code is reviewed before every merge.

  4. 4

    Beta testing

    We test across iPhone sizes, older supported devices, VoiceOver, low power mode and weak networks, then run a TestFlight beta with real users before the public release. Feedback from testers is triaged and fixed before submission.

  5. 5

    App Review

    We prepare metadata, screenshots, privacy nutrition labels and review notes, submit the build, handle any reviewer questions, and plan a phased release to limit risk. Phased release lets us pause the rollout if crash rates rise unexpectedly.

FAQ

Frequently asked questions

Anything else about iOS development? Ask us directly.

  1. Native Swift makes sense when your app leans on Apple-specific features, heavy animation, health or hardware data, or when most of your customers use iPhone. If you need iOS and Android at once on a tighter scope, React Native may fit better. We walk through your feature list and audience during discovery and recommend one honestly.
