Kotlin Multiplatform: code sharing without compromise

on YouTube ↗34m

" summary

Kotlin Multiplatform shares concrete modules — a Sudoku solver, JSON via kotlinx.serialization, and a storage layer implemented with expect/actual — compiled for JVM JS and native. It uses the Gradle multiplatform plugin, SQLDelight for DB options, coroutines (Android threads OK, native coroutines single‑threaded), and Kotlin/Native frameworks with the single‑framework limit. Result: Android build is fully playable, iOS mostly works via Xcode, JS shows a noninteractive demo, seeded RNG produces identical boards across platforms.
