Declarative UI ❤️ Kotlin Multiplatform!

on YouTube ↗36m

" summary

Live-codes a working Android and iOS app that shares networking, JSON parsing and persistence so one Kotlin module powers both UIs; uses Kotlin Multiplatform, renders UI with Jetpack Compose + SwiftUI, and wires networking and storage with Ktor, kotlinx.serialization, SQLDelight and Koin. The app fetches “people in space” from a remote API, stores results in SQLite via SQLDelight, exposes flows/state to Compose/SwiftUI so DB changes immediately update the lists, and the build runs successfully on both platforms.
