iOS App Development

Swift apps that feel like Apple built them

Swift and SwiftUI applications for iPhone, iPad and Apple Watch — fast launches, offline-first data, background location, widgets and Live Activities. We handle the whole lifecycle from architecture to App Store review and phased rollout.

01Why iOS

What iOS does better than the alternatives

01

First-class platform features

Everything Apple ships on day one — SwiftUI, Swift Concurrency, WidgetKit, ActivityKit, MapKit, ARKit — is available without waiting for a bridge or plugin.

02

Predictable performance

Compiled Swift, no JavaScript runtime, no bridge serialisation. Smooth 120 Hz scrolling and quick cold starts on every supported device.

03

Offline and background done right

Background tasks, silent push, Core Data/GRDB persistence and URLSession background transfers — the tools to build apps that keep working in the field.

04

Enterprise distribution options

App Store, TestFlight, Apple Business Manager and MDM — we have shipped through all of them, including regulated and government clients.

Choose iOS when

  • Your users are primarily on iPhone or iPad and expect platform-native polish
  • You need deep hardware access: ARKit, Core Location, Core Bluetooth, NFC, camera pipelines
  • Widgets, Live Activities, App Clips, Siri or watchOS are part of the product
  • Performance and battery life matter more than sharing code with Android

Not sure it fits? Compare with the alternatives below or ask us — recommendations are part of every consultation.

iOS vs. alternatives

02What we build with it

iOS in production

Field data collection

Offline forms, photos, GPS tracks and map layers synced to ArcGIS or PostGIS when the connection returns.

Consumer utilities

High-download utility and lifestyle apps where store rating, launch speed and accessibility decide retention.

Maps and navigation

MapKit, Mapbox and ArcGIS Maps SDK for iOS with custom layers, turn-by-turn and offline tiles.

IoT companions

Bluetooth LE and NFC apps that pair with sensors, wearables and industrial devices.

Wearables and widgets

watchOS companions, WidgetKit home-screen widgets and Live Activities for time-sensitive status.

AR experiences

ARKit and RealityKit for on-site visualisation of assets, plans and underground utilities.

03How we work with iOS

6 ways we deliver on iOS

From greenfield builds to rescues and migrations — each engagement is scoped, estimated and delivered by engineers who work in iOS daily.

01

Architecture & greenfield builds

SwiftUI-first apps with clean, testable architecture (MVVM or TCA), async/await networking and dependency injection that keeps features independent as the app grows.

  • SwiftUI
  • Swift Concurrency
  • Combine
  • TCA

02

Offline storage & sync

Local persistence with Core Data, SwiftData or GRDB; conflict-aware sync against REST, GraphQL or ArcGIS feature services; background uploads that survive app termination.

  • Core Data
  • SwiftData
  • GRDB
  • BackgroundTasks

03

Mapping & location

MapKit, Mapbox Maps SDK and ArcGIS Maps SDK for Swift — custom vector layers, clustering, offline map packages, geofencing and precise background tracking.

  • MapKit
  • Core Location
  • ArcGIS Maps SDK
  • Mapbox

04

Objective-C / UIKit modernisation

Incremental migration of legacy Objective-C and UIKit codebases to Swift and SwiftUI, module by module, with the app shipping throughout.

  • UIKit
  • Swift Package Manager
  • XCTest

05

CI/CD & App Store release

Xcode Cloud or Fastlane pipelines, automated signing, TestFlight beta groups, review-note preparation, phased release and crash triage after launch.

  • Xcode Cloud
  • Fastlane
  • TestFlight
  • App Store Connect

06

Testing & accessibility

Unit and UI tests, snapshot tests, performance baselines in Instruments, and VoiceOver/Dynamic Type compliance for public-sector accessibility requirements.

  • XCTest
  • Instruments
  • Accessibility Inspector

04Where it sits

iOS in a complete stack

No technology ships alone. This is the reference architecture we start from on iOS projects — the highlighted layer is where iOS lives; the rest is chosen to fit your data, hosting and team.

05Honest comparison

iOS or something else?

iOS vs Flutter

Choose native iOS when you need day-one platform APIs, the smallest binary and Apple-grade animations; choose Flutter when one team must ship the same custom UI on both stores.

iOS vs React Native

Choose native iOS for hardware-heavy or performance-critical apps; choose React Native when your organisation already runs on React and wants shared logic with the web.

Still undecided? The mobile technology guide walks through when we recommend each option.
