📂 Project Structure

/composeApp

Path: ./composeApp/src

This module contains code shared across Compose Multiplatform applications.

Subfolders:

• commonMain (./composeApp/src/commonMain/kotlin)
  Code shared across all Compose targets.

• Platform-specific folders
  Used when code is required only for a specific platform:

  • iosMain → iOS-specific code (e.g., Apple CoreCrypto)
  • jvmMain → Desktop (JVM) specific code
  • Other folders follow the same naming convention

---

/iosApp

Path: ./iosApp/iosApp

Contains the iOS application entry point.

Even when using Compose Multiplatform UI, this module is required. This is also where SwiftUI code should be added.

---

/server

Path: ./server/src/main/kotlin

Contains the Ktor server application.

---

/shared

Path: ./shared/src

Contains code shared across all targets in the project.

• commonMain (./shared/src/commonMain/kotlin)
  The most important folder for shared business logic.

Platform-specific folders can also be used here if required.
