Development Environment


  • machine running macOS installed Xcode 9.2
  • Apple developer program account
  • iOS devices for running binary (iOS Simulator is unavailable for Kotlin/Native)
  • CLion (optional)


To compile Kotlin/Native use following steps:

git clone https://github.com/JetBrains/kotlin-native.git
cd kotlin-native
./gradlew dependencies:update
# this may take around a hour
./gradlew dist distPlatformLibs
export PATH=./dist/bin:$PATH

You can find Kotlin/Native introduction in here.

The instance of Kotlin/Native iOS app is KotlinConf 2017 app. We reference it to write codes.

How to build iOS app

  1. (optional) Open ios/ directory with CLion.
  2. (optional) Write your code. Put your code under ios/src/main/kotlin/.
  3. Open ios/DroidKaigi2018.xcodeproj with Xcode.
  4. Connect your iOS device to your mac.
  5. Choose your iOS device as running target.
  6. In Xcode, select your Team at DroidKaigi2018 > General Tab > (in left pain TARGET) DroidKaigi2018 > Signing Section > Team pull down menu.
    • If you have no team options, choose Add an Acount... and add your Apple ID.
    • Maybe you can find your Personal Team.
  7. Run and you can find DroidKaigi2018 app in your home screen!
    • If you using Personal Team, in first time, you have to accept your Signing Certificate from Settings.app > General > Device Management .

How to add new pod

It's little confusing for me (and maybe you).

  1. Add new pod into Podfile normally.
  2. Archive pod as framework. (Select that scheme in Xcode and Product > Archive)
  3. Copy framework from DerivedData into Frameworks directory.
  4. Add header files we want to use in Kotlin, linker/compiler options into src/main/c_interop/libs.def.
  5. Run compileKonanLibs gradle task.


This project uses some modern libraries and source codes.
