Performance
Compiled, not bridged
Swift compiles straight to machine code for the iPhone’s chip. There is no runtime interpreting your app and no bridge passing messages to native views.
Swift
LLVM
ARM64
JS / Dart
Bridge
Native views
We only write Swift.Here is why.
Native Swift and SwiftUI on every project. No React Native, no Flutter, no web wrapper. A narrower offer, on purpose.
Four reasons
01
What one language buys your app
Reliability
Mistakes caught before release
Swift’s type system stops whole classes of bugs at compile time, before they can reach a user.
let price: Int = "12"
Cannot convert value of type 'String' to specified type 'Int'
Access
Every Apple framework
Widgets, Live Activities, Siri, payments, health and on-device ML. All of it, with no wrapper library in between.
- WidgetKit
- ActivityKit
- App Intents
- StoreKit
- HealthKit
- Core ML
- Vision
- ARKit
- PassKit
- MapKit
- CloudKit
- SwiftData
Direction
Where Apple is going
Every major iOS capability of the last decade arrived in Swift first. Building in Swift means building on Apple’s own roadmap.
- 2014Swift 1.0
- 2019SwiftUI
- 2021async/await
- 2023Macros, SwiftData
- 2024Swift 6
Side by side
02
Swift and cross-platform, honestly
Cross-platform frameworks are good at one thing native cannot do. Everything else tilts the other way.
Native Swift
Cross-platform
Runtime
Compiled native code
A JavaScript or Dart runtime
New iOS APIs
Available on day one
When a plugin or bridge supports them
Interface
Apple’s own system controls
Recreated or wrapped controls
Accessibility
VoiceOver and Dynamic Type built in
Depends on the framework’s support
Animation and gestures
UIKit and SwiftUI, as iOS ships them
Through the framework’s own layer
Android from one codebase
No
Yes
The obvious question
03
But what about React Native or Flutter?
They have their place. If you need iOS and Android from one budget on day one, a cross-platform framework can be the right call, and we will tell you so.
But if the app has to feel at home on iPhone, use what Apple ships the day it ships, and stay easy to maintain for years, native Swift is the safer bet.
That is the only kind of app we build. Doing one thing is what lets us do it properly.
