You will need either IntelliJ IDEA (Ultimate is preferred but the Community edition works too!) or CLion (Note: as of kotlin version
1.4 the CLion Kotlin/Native plugin is deprecated! Use Intellj IDEA if you are using kotlin version
1.4 or above!). The easiest way to install them is via the JetBrains Toolbox app.
Regardless of what IDE you choose, you need to install the appropriate Kotlin plugin. This can be done within the IDE (
Settings -> Plugins). You have to install
Kotlin plugin for IntelliJ IDEA while install
Kotlin/Native for CLion plugin for CLion.
Once you have the plugin installed, you can start importing your project.
Import Project and select your project's
build.gradle.kts file. The IDE will take some time to index your project, but once done you can start coding!
