Build native apps for iPhone and Android with Skip
Skip brings Swift app development to Android. It is a tool that enables developers to write a mobile app in a single modern programming language (Swift) using a first-class development environment (Xcode) to build genuinely native apps for both iOS and Android.
How Skip Works
As you build your SwiftUI app in Xcode, the skipstone Xcode plugin continuously transpiles it into the equivalent Jetpack Compose for Android. This creates a user interface that is a genuinely native, both on Android and iOS.
Benefits of a Dual-Platform Skip App
Skip apps don’t just “look native”, they are native: Swift and SwiftUI on iOS, Kotlin and Compose on Android. You know the difference, and so do your users.
When you use Skip, no part of your app is hidden from your view… or from your debugger. Skip transpiles your Swift directly into Kotlin source code that you can inspect and customize.
With SkipZero, your iOS app has no dependencies on any Skip frameworks. And the resulting Android app only requires a few Skip open source libraries.
With no additional managed runtime, Skip apps are as efficient as they can possibly be on both platforms: bare metal on iOS and ART bytecode on Android.
An Idyllic IDE
Skip’s IDE is Xcode, the premiere app development environment for iOS. For serious Android customization, open the generated code directly in Android Studio.
Skip generates standard Kotlin and Compose, so integrating with Android libraries is painless. Call other Kotlin and Java code directly, with no bridging required.
Skip’s transpiler is only half the story. The frameworks that underpin iOS app development, such as Foundation and SwiftUI, are made available on Android through Skip’s free and open-source reimplementations.
Skip transpiles unit tests too! You can ensure that your logic performs identically across platforms. Run your tests headlessly either locally or remotely, making acceptance testing a breeze.
Your code is your own – both the Swift inputs and Kotlin outputs – so you aren’t locked into an ongoing dependency on the Skip transpiler.
