Hitchhiker’s Guide to Kotlin Multiplatform Libraries
summary
Five years of concrete examples: 11 KMP samples showing cross‑platform apps (Android, iOS, desktop, web) that actually run with shared view models and shared Compose UI. Key toolchains used are Ktor + SQLDelight + Coin for networking, persistence and DI, Apollo + Decompose for GraphQL and component navigation, and Realm + KMP observable view model for object persistence and Swift interop. Built artifacts include a proxy backend to augment missing API fields and generated Swift packages from shared modules, and these approaches work in production‑style samples.
