Swift development
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.
In short
Swift, at a glance
- Compiled Swift and Metal-backed rendering: 120Hz smooth, instant launch.
- Every gesture, transition and haptic exactly as iOS users expect.
- Day-one access to every new iOS capability, no bridge layer waiting.
- Keychain, Secure Enclave and on-device processing for sensitive products.
Why Swift
Swift in production.
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.
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.
How we engineer
with Swift.

Quality
A look at what we've shipped.
A real-time wealth platform built for scale
Re-architecting a legacy investment portal into a modular, real-time platform that holds up under heavy concurrent load.
View case studyA six-step cycle, repeated until it's right.
Transparent, predictable and collaborative. You always know what's shipping next and why.
Discovery
We map the business, users and constraints, then pressure-test the problem before a line of code.
Planning
Architecture, scope, and a sprint roadmap with clear milestones, budgets and success metrics.
Design
Research-led UX and high-fidelity interfaces, validated with prototypes before build.
Development
Senior-led engineering in two-week sprints with demoable increments and continuous review.
Testing & QA
Automated and manual testing, security review and performance hardening before release.
Launch & Care
Confident deployment, monitoring and SLA-backed support that keeps things humming.
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 smooth 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.
