APP DEVELOPMENT
THAT DELIGHTS
From polished consumer apps to complex enterprise iOS platforms — we engineer native Swift & SwiftUI applications that feel unmistakably Apple and perform at native speed.
iOS APP DEVELOPMENT
SERVICES THAT DELIVER
Whether you need a polished consumer app, a complex enterprise iOS platform or a companion watchOS experience — we've shipped it before and we'll build it better.
Custom iOS Applications
Bespoke SwiftUI apps engineered around your product requirements — clean architecture, state management, networking and App Store compliance done right.
Explore →Enterprise & B2B iOS Apps
MDM-ready internal tools, field-service apps and B2B platforms with SSO, offline-first sync and role-based access — built for thousands of daily users.
Explore →Apple Watch & watchOS Apps
Companion watchOS experiences with complications, background refresh and HealthKit integration — extending your iOS app to the wrist.
Explore →Migration & Modernisation
Migrate legacy Objective-C or UIKit codebases to modern Swift and SwiftUI with full test coverage and zero feature regression.
Explore →Performance & App Store Optimisation
Launch time tuning, memory profiling with Instruments, crash-rate reduction and ASO-ready metadata — apps that score high and rank higher.
Explore →UI Component Library & Design Systems
Reusable, accessible SwiftUI component libraries with design tokens synced from Figma — the foundation every fast-moving product team needs.
Explore →SENIOR iOS ENGINEERS,
NOT JUNIOR SHOPS
We are a specialist iOS engineering studio. Every project is led by a senior engineer with production experience in your specific domain — health & fitness, fintech, EdTech or enterprise tooling. No bait-and-switch, no offshore handoffs.
Test-First Development
XCTest, XCUITest and Swift Testing — every feature ships with unit and UI tests, so refactors never break production.
Swift 6 by Default
Strict concurrency checking across every project — data races caught at compile time before they ever reach your users.
Accessibility Baked In
VoiceOver, Dynamic Type and full Apple HIG compliance from day one — tested with real assistive technology on every build.
OUR iOS DELIVERY PROCESS
Discovery & Scoping
We audit your requirements, target devices and user flows to define an app architecture and data model before writing a line of Swift.
Design System Setup
Figma design tokens translated to SwiftUI view modifiers, an Xcode project scaffolded, and API contracts agreed with your backend team.
Iterative Build
Two-week sprints with TestFlight builds pushed to your device — you see and test every feature before it merges to main.
QA & Performance
Automated XCTest suite, Instruments profiling, real-device testing across screen sizes and an accessibility audit before every release.
Launch & App Store Submission
App Store Connect setup, review-guideline compliance check, submission handling and optional retainer support post-launch.
EVERYTHING YOUR iOS
PROJECT NEEDS
From greenfield SwiftUI apps to incremental Objective-C rewrites — a complete iOS capability under one roof, so you never need to stitch together multiple agencies.
App Architecture
MVVM, TCA and clean architecture patterns with modular Swift packages.
Async & Reactive State
Swift Concurrency, async/await, Combine and observation macros wired end to end.
Local Storage & Sync
SwiftData, Core Data and CloudKit sync for reliable offline-first experiences.
Auth & Keychain
Sign in with Apple, OAuth, biometric unlock and secure Keychain-backed sessions.
Push Notifications
APNs setup, rich notifications, silent push and notification service extensions.
AI-Powered Features
On-device Core ML models, Apple Intelligence integration and smart features that run offline.
WHY TEAMS CHOOSE DATABOXSTUDIO FOR iOS
Clean, Maintainable Code
SwiftLint, SwiftFormat, conventional commits and enforced architecture boundaries — codebases your future team will thank us for.
Fully Concurrency-Safe
Strict Swift 6 concurrency from networking layer to view — catching data races at compile time before they reach your users.
Sub-Second Launch Times
Lazy loading, background prefetching and Instruments-driven profiling — App Store performance metrics that actually matter.
Transparent Delivery
Weekly demos, live TestFlight builds and a shared Linear board — you see every commit before it ships.
iOS EXPERTISE
ACROSS EVERY VERTICAL
We've built iOS applications for companies at every stage — from seed-funded startups to publicly listed enterprises across a wide range of industries.
RESULTS THAT SPEAK
FOR THEMSELVES
WHAT OUR iOS CLIENTS SAY
Real feedback from product teams who trusted us with their iOS applications.
DataboxStudio rebuilt our Objective-C app in Swift + SwiftUI in 12 weeks. Crash-free sessions went from 96% to 99.9%, and our App Store rating climbed from 3.4 to 4.7 within two months of launch.
We needed a real-time trading app in SwiftUI that handled live price streams without dropping a frame. DataboxStudio delivered — smooth 120fps ProMotion scrolling even under heavy load. Genuinely impressive engineering.
Our fitness app ships with a companion watchOS complication that shares 90% of its logic with the iPhone app. DataboxStudio architected the entire Swift package structure and it's been rock solid for two years.
