When the iPhone experience is the product, native Swift is the answer. We build SwiftUI apps that use the platform's full surface — widgets, Live Activities, on-device ML — with the polish App Store features demand.

(01)Overview

What we build with Swift.

Swift is fast, type-safe and expressive, and SwiftUI made native UI declarative — the productivity of modern frameworks with zero compromise on platform feel.

We go native when the product demands what only the platform offers: deep hardware access, instant responsiveness, widgets and watch companions, and the design polish Apple users notice immediately.

SwiftUI apps

Declarative, animation-rich interfaces on Apple's current stack.

Platform features

Widgets, Live Activities, App Intents and watchOS companions.

On-device ML

Core ML and Vision for private, instant intelligence.

UIKit modernisation

Legacy UIKit estates moved to SwiftUI incrementally.

(02)Why Swift

The case for Swift.

The properties that make Swift the right foundation — not a trend, but a deliberate engineering choice.

Native performance

Compiled Swift and Metal-backed rendering — 120Hz smooth, instant launch.

Platform-perfect feel

Every gesture, transition and haptic exactly as iOS users expect.

Full API surface

Day-one access to every new iOS capability, no bridge layer waiting.

Privacy & security

Keychain, Secure Enclave and on-device processing for sensitive products.

App Store advantage

Native polish is what featured placements and ratings are made of.

Type-safe & modern

Swift's safety and concurrency model catch bugs before they ship.

(07)FAQ

Swift questions, answered.

Still unsure if Swift is right for your project? A senior engineer will tell you straight on a free call.

Native when the iPhone experience is the differentiator — deep platform features, maximum polish, on-device ML. Flutter when one team must ship both stores fast. We build both and will tell you honestly which your product needs.

Yes — it's Apple's strategic UI framework and our default for new apps. Where an edge case needs UIKit, the interop is seamless and we use it surgically.

Yes, incrementally: new screens in SwiftUI, legacy screens migrated by priority, full interop in between. Users see steady improvement, not a risky rewrite.

End to end — provisioning, review-guideline compliance, phased rollouts and the listing itself. We've shipped enough apps to keep review friction near zero.

We build native Kotlin for Android (see our Kotlin page) or Flutter when one codebase should serve both. The right answer depends on where your users and differentiation live.
