Project Structure

This is a Kotlin Multiplatform project targeting Android, iOS, Web, and Desktop (JVM).

📱 /iosApp

Contains the iOS application entry point.
Even when sharing UI with Compose Multiplatform, iOS still requires:

• An Xcode project
• Swift/SwiftUI integration points
• App lifecycle setup

🌍 /shared

Shared Kotlin Multiplatform module containing:

• UI (Compose Multiplatform)
• ViewModels
• Networking (Ktor)
• Models
• Repository layer
• Design system

Subfolders:

• commonMain — shared code for all platforms
• androidMain — Android‑specific implementations
• iosMain — iOS‑specific implementations (e.g., CoreCrypto, platform APIs)
• jvmMain — Desktop‑specific code
• jsMain / wasmJsMain — Web‑specific code

This structure allows platform‑specific optimizations while keeping most logic shared.
