Basic SQLite sample app.
If you want to see a fully architected example, with Sqldelight and other libraries, check out DroidconKotlin.
./gradlew build
Then open the ios project under notepad/ios/calculator
If in Intellij, make sure you create an Android app run config. It's Android running basic sqlite code, so apart from the fact that it's multiplatform, not much else to talk about.
Until the new Multiplatform gradle plugins and dependencies are stable, you need to stick to Gradle 4.7.
