// APP DEVELOPMENT
Apps engineered for Apple's platforms.
We develop native apps for Apple's platforms in Swift and SwiftUI — structured for performance, built for the App Store and made to live long after launch.
// PLATFORMS
One codebase, the whole Apple ecosystem
- iOS
- iPadOS
- macOS
- watchOS
- visionOS
// WHY NATIVE
Why native — and why Apple
Native isn't the harder choice, it's the better one. It produces apps that feel at home on the platform, perform without compromise, and keep pace as Apple evolves its systems.
-
01
Performance
Straight to the platform APIs — no abstraction layers between the code and the hardware. Fast, fluid and energy-efficient.
-
02
Platform-true UX
Apps that follow Apple's Human Interface Guidelines and feel right — gestures, navigation and details users already know.
-
03
Longevity
Native code ages well. When Apple ships new OS versions and devices, the path forward is clear — not a framework to wait on.
// ARCHITECTURE
Architecture for apps
An app is a system, not a collection of screens. We structure it in clear layers, each with a single responsibility — so the interface can change without breaking the logic, and the logic can be tested without an interface. We work with MVVM and clean architecture, modularised so parts can be swapped, tested and reused.
-
01
UI
SwiftUI views and presentation logic — what the user sees and touches.
-
02
Domain
Business rules and use cases, independent of frameworks and UI.
-
03
Data
Repositories, persistence and networking behind clean interfaces.
-
04
Platform
Apple's frameworks and system services — called, never abstracted away.
// TECH
The tech we work in
Modern Apple development, from first prototype to release pipeline.
- Swift
- SwiftUI
- UIKit
- Combine
- Swift Concurrency (async/await)
- Core Data
- SwiftData
- CloudKit
- App Store Connect
- TestFlight
- XCTest
- Xcode Cloud
- CI/CD
// PROCESS
From architecture to the App Store
The road to the App Store isn't something we improvise at the end — it's built into how we work from day one.
-
01
Architecture
We define structure, data model and modules — the foundation everything else is built on.
-
02
Implementation
Features are built in short iterations, with code review and tests close to the code.
-
03
QA & TestFlight
We test on real devices and distribute via TestFlight for feedback before release.
-
04
Submission & iteration
We prepare for App Store review, submit, and keep maintaining after launch.
App Store review readiness built in. We prepare metadata, privacy labels, permissions and guideline compliance well ahead of time — so submission is a formality, not a surprise.
// QUALITY
Quality & craft
The details that separate an app that works from an app that feels inevitable.
-
HIG-aligned
Built to Apple's Human Interface Guidelines — apps that feel native to the platform.
-
Accessibility
VoiceOver, Dynamic Type and contrast from the start — not an afterthought.
-
Performance budgets
We measure launch time, frame rate and memory — and keep them within set limits.
-
Privacy-by-design
Minimal data collection, clear privacy nutrition labels and respect for the user's trust.
