Native Swift & Kotlin Development

When a feature demands the platform’s full capability, we build it fully native

Some features — deep camera control, ARKit/ARCore, background processing, or platform-exclusive APIs — need direct access to Swift on iOS and Kotlin on Android rather than a cross-platform abstraction layer. We build fully native when performance or platform capability requires it, and integrate it cleanly alongside cross-platform code where it doesn’t.
Going fully native isn’t about distrust of cross-platform tooling — it’s about recognizing where the abstraction layer genuinely costs something. A cross-platform framework has to expose a common API surface across both operating systems, which means it’s inherently a step behind whatever Apple or Google shipped in their latest OS release. For apps where being first to support a new capability matters, or where a feature is compute-intensive enough that every layer of abstraction has a real performance cost, native is the right call.

Implementation

How We Actually Build This

1

Swift (with SwiftUI or UIKit) is used for iOS-specific modules, giving direct access to the latest Apple frameworks on release day

2

Kotlin (with Jetpack Compose) handles Android-specific modules with the same direct access to current Android capabilities

3

Native modules are built to plug cleanly into a cross-platform shell where one exists, rather than forcing an entire rewrite for one feature

4

Platform-specific performance profiling (Instruments on iOS, Android Profiler) is used to validate that native modules meet their performance targets before release

Key Benefits

Why Native Swift & Kotlin Development Is the Right Choice

Full access to platform-exclusive APIs and the latest OS capabilities

Best possible performance for compute- or graphics-intensive features

First access to new iOS/Android features on release day

Deeper integration with platform-specific hardware (camera, sensors, biometrics)

Can be embedded as native modules inside a React Native/Flutter app

Proven at Scale

Companies Building on This Technology

Airbnb & Pinterest

have both migrated performance-critical Android surfaces to Kotlin

Netflix

uses Kotlin extensively across its Android engineering

Where This Applies

Common Use Cases

  • AR/camera-heavy features requiring full platform hardware access
  • Apps needing day-one support for new iOS/Android OS capabilities
  • Performance-critical modules embedded inside a cross-platform app
  • Apps with deep platform-specific integrations (widgets, wearables, CarPlay)

Frequently Asked Questions

Common Questions About Native Swift & Kotlin Development

Do we need two separate teams for iOS and Android if we go fully native?+

Typically yes, or engineers cross-trained in both — this is the real tradeoff against cross-platform: full native access comes at the cost of maintaining two codebases instead of one.

Can native modules be added later, after launching with a cross-platform app?+

Yes — this is a common and recommended pattern: launch cross-platform for speed, then add native modules for specific features once you know exactly which capabilities actually need the deeper platform access.

Is native development significantly more expensive?+

Building and maintaining two codebases costs more than one, but for apps where a specific feature is the core value proposition (advanced AR, professional camera control), the performance and capability gain is usually worth the added cost for that specific module.
