Multiplatform sample

This example shows how to use Kotlin/Native in the multiplatform world.

This sample based on the Jetbrains example.

It is different in some ways:

• It has a "common" dependency in the commonMain source set, the networking library ktor. This is then used by the iOS/Native and Android project by their respective implementation
• This includes use of co-routines
• It does not use an "androidLib" template, since this has bugs

iOS

To compile the project from Xcode or Appcode just open iosApp/iosApp.xcodeproj and run the application. The swift tests also can be executed from Xcode/Appcode

This works because there is a custom shellscript build phase in the MPP framework that rebuilds the framework.

To compile a framework for ios simulator from the command line yourself execute:

./gradlew :mpp:build

To compile the framework for a device use the device project property:

./gradlew :mpp:build -Pdevice=true

To run kotlin tests (including the common ones) after they're compiled by Kotlin/Native:

./gradlew :mpp:iosTest

If you do not have the Android SDK installed, you can define an environment variable which will skip the Android specific parts of the build:

MPP_NO_ANDROID_SDK=true ./gradlew iosTest

You can also add this variable to the custom shell script in the Framework build in XCode.

Android

The application can be built and executed on a device or emulator using Android Studio (tested with 3.2).

One can also compile the application and run tests from the command line:

./gradlew :mpp:build

If you're not on macos, you can run only the android part:

./gradlew mpp:assembleDebug
