The Module's Recipe

The shared build.gradle.kts is the recipe for your module: which targets to build and which libraries to pull in.

Plugins Come First

At the top, the plugins block turns on multiplatform support. Without it, Kotlin has no idea about targets.

plugins {
    kotlin("multiplatform")
    id("com.android.library")
}

The kotlin {} Block

Everything multiplatform lives inside the kotlin block. This is where targets and source sets are declared.

kotlin {
    // targets and source sets go here
}

Declaring Android

The androidTarget line tells Kotlin to produce an Android library artifact from your shared code.

kotlin {
    androidTarget()
}

Declaring iOS

iOS needs a few targets, one per architecture, so it runs on simulators and real devices alike.

iosX64()
iosArm64()
iosSimulatorArm64()

Naming the Framework

A binaries.framework entry names the iOS framework Swift will import. Pick a clean name your iOS team will type often.

iosArm64 {
    binaries.framework {
        baseName = "Shared"
    }
}

Source Set Dependencies

The sourceSets block lists libraries per set. commonMain gets cross-platform deps; platform sets get their own.

sourceSets {
    commonMain.dependencies {
        // shared libraries
    }
}

Common Dependencies Are Shared

A library added to commonMain must support every target. Add it here and all platforms can use it.

commonMain.dependencies {
    implementation("io.ktor:ktor-client-core:2.3.0")
}

Platform Dependencies

Platform-only libraries go in their own set, like an Android engine that only the JVM target understands.

androidMain.dependencies {
    implementation("io.ktor:ktor-client-okhttp:2.3.0")
}

Android Config Block

A separate android block sets the namespace and SDK levels for the Android library half of the module.

android {
    namespace = "com.example.shared"
    compileSdk = 34
}

Read It Top to Bottom

To grok any shared build file, read it as a story: plugins, then targets, then source sets, then platform config. 📖

Quick Check

Where does a cross-platform library belong?

Recap

The shared build.gradle.kts flows plugins to targets to source sets. Common deps for all, platform deps for one.
