Technology

Overview

This is a Kotlin Multiplatform project targeting Android, iOS and Server.

• /composeApp is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:

  • commonMain is for code that’s common for all targets.
  • Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, iosMain would be the right folder for such calls.

• /iosApp contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.

• /server is for the Ktor server application.

• /shared is for the code that will be shared between all targets in the project. The most important subfolder is commonMain. If preferred, you can add code to the platform-specific folders here too.
