Build cross-platform applications with shared Kotlin code.

Topics Covered

Project Setup

kotlin {
    androidTarget()
    listOf(iosX64(), iosArm64(), iosSimulatorArm64()).forEach {
        it.binaries.framework { baseName = "Shared"; isStatic = true }
    }
    sourceSets {
        commonMain.dependencies {
            implementation("io.ktor:ktor-client-core:2.3.8")
        }
        androidMain.dependencies { implementation("io.ktor:ktor-client-okhttp:2.3.8") }
        iosMain.dependencies { implementation("io.ktor:ktor-client-darwin:2.3.8") }
    }
}

expect/actual

// commonMain
expect class SecureStorage { fun get(key: String): String? }

// androidMain
actual class SecureStorage { actual fun get(key: String) = prefs.getString(key, null) }

// iosMain
actual class SecureStorage { actual fun get(key: String) = KeychainWrapper.get(key) }

Troubleshooting

Issue	Resolution
"No actual for expect"	Add implementation in platform source set
iOS framework not found	Run linkDebugFrameworkIos task
