Export Dependencies To Kotlin

How It works

On completion with using external dependencies, it's possible to export them to Kotlin, if they are compatible.

Exported dependency can be used inside the bridge, the Swift & Kotlin App.

Note

If your package doesn't work with the plugin, please create an issue.

Bridge Incompatible Dependencies

In a case the exported dependency is written in Swift, manual work needs to be done like this.

For example, the CryptoSwift can't work directly on Kotlin, so the Plugin's bridge is here to fill the hole between Kotlin and Swift.

Gradle

The following configuration export to Kotlin the package FirebaseAnalytics which is a ObjC library.

Don't export incompatible library

Exporting an incompatible library is useless and will only increase build time.

build.gradle.kts

swiftPackageConfig {
    create("[cinteropName]") {
        dependency {
            remotePackageVersion(
                url = URI("https://github.com/firebase/firebase-ios-sdk.git"),
                products = {
                    add("FirebaseAnalytics", exportToKotlin = true), // exported
                    add("FirebaseCore") // non-exported
                },
                version = "11.8.0",
            )
            // Another SwiftDependency
            // ...
        )
    }
}

Warning

A local swift package is being generated during the build and this message displayed

Spm4Kmp: A local Swift package has been generated at
/path/to/the/local/package
Please add it to your xcode project as a local package dependency.

Add the folder to your Xcode project as a Local package, that's all.

Note : When updating your configuration, reset the package cache to apply the modification.

Example

iosMain/kotlin/com/example/myKotlinFile.kt

import FirebaseAnalytics.FIRConsentStatusGranted

@ExperimentalForeignApi
val consentStatusGranted = FIRConsentStatusGranted

Note

The bridge can remain empty as we don't need it; we only want to use the exported product.
