## What it is
Skip is an open-source toolchain that lets developers build native iOS and Android apps from a single Swift/SwiftUI codebase. It compiles Swift natively for Android (Skip Fuse) or transpiles it to Kotlin (Skip Lite), mapping SwiftUI to real Jetpack Compose with no added runtime.

## Use cases
- build an iOS and Android app from one Swift codebase
- port an existing SwiftUI app to Android
- write Android apps in Swift instead of Kotlin
- share business logic between iOS and Android in Swift
- avoid learning Dart or JavaScript for cross-platform development
- transpile Swift code to Kotlin for Android interoperability

## When to choose
- your team already knows Swift and SwiftUI and wants Android reach
- you want truly native UI and performance on both platforms with no runtime overhead
- you develop on macOS in Xcode and want Android builds alongside iOS
- you need per-module control between native compilation and Kotlin transpilation

## When to avoid
- you need platforms beyond iOS and Android
- your team is more fluent in Kotlin, Dart, or JavaScript than Swift
- you rely heavily on iOS-specific frameworks with no Android equivalent and don't want to maintain fallbacks
- you develop on Linux or Windows, since Skip requires macOS with Xcode
