Basic Configuration

Gradle

The following configuration is a simple bridge between Kotlin and Swift.

build.gradle.kts

swiftPackageConfig {
    create("[cinteropName]") {
    }
}

When syncing the project, the plugin creates a folder at src/swift/[cinteropname].

The content of this folder is your bridge between Swift and Kotlin, it can contain only Swift source files or no file.

Example

Make your Swift code compatible with Kotlin.

Your Swift code needs to be marked as @objc/@objcMembers and the visibility set as public or it won't be exported and available from your Kotlin code.

src/swift/[cinteropname]/mySwiftFile.swift

@objcMembers public class MySwiftBridge: NSObject {
    public func exportedMethod() -> String {
        return "value"
    }
}

iosMain/kotlin/com/example/myKotlinFile.kt

import [cinteropname].MySwiftBridge

val contentFromSwift = MySwiftBridge().exportedMethod()
