About Skip
Skip is an open source tool that lets you write one app in Swift and SwiftUI and ship it natively on iOS and Android. It is Apache 2.0 licensed and designed to fit into an Xcode workflow.
What it does
Skip compiles Swift for iOS and produces Jetpack Compose code for Android. Each platform uses its own recommended UI toolkit, so system themes, accessibility and platform conventions work as expected. The tool adds no runtime or engine to the shipped app. You can keep working in Xcode and use Android Studio when you need platform-specific tuning.
Key features
- One Swift and SwiftUI codebase
- Native SwiftUI on iOS and Jetpack Compose on Android
- No added runtime in the shipped app
- Call Kotlin and Java APIs from shared code
- Launch iOS and Android simulators together
Who it's for
Skip suits iOS developers who want an Android version without writing the whole app again in Kotlin. It also fits small teams that want native performance and platform conventions on both systems.
Pricing and good to know
Skip is free and open source. It is community funded, and the site lists sponsor options. Because the Android side is generated from Swift, check how the build handles any iOS-only frameworks you plan to use. You will need Android Studio or an Android emulator to test the Android version.
Highlights
- Write one Swift and SwiftUI codebase for both platforms
- Get native SwiftUI on iOS and Compose on Android
- Call Kotlin and Java libraries from shared code
- Run iOS and Android previews side by side
