A target is a platform your Kotlin code compiles to. One shared codebase can produce builds for several targets at once. 🎯

Android is the most common starting target. Kotlin compiles to JVM bytecode, the same format Android apps have always used.

For iOS, Kotlin compiles ahead of time into a native binary using Kotlin/Native, packaged as a framework Swift can call.

Desktop apps for Windows, macOS, and Linux run on the JVM too. The same desktop target serves all three operating systems.

Kotlin can target the browser by compiling to JavaScript or to WebAssembly, so shared logic runs on the web as well.

On the backend, Kotlin runs on the JVM server side. You can even share models and validation between your app and your API.

You list targets in your Gradle build. Each call like androidTarget adds one platform to the shared module.

You do not have to ship every target. Most teams start with just Android and iOS and add more targets only when needed.

iOS itself has a few targets: real devices use arm64, while the simulator uses x64 or arm64 depending on your Mac.

Every target reads from your common code. That shared source set is compiled fresh for each platform you declared.

The magic is reach: a single Kotlin codebase becomes an APK, an iOS framework, a desktop app, and more from one build.

Let's confirm what targets are.

Targets are the platforms you compile to: Android, iOS, desktop, web, and server. Declare only the targets your team actually needs. 🌍
