Bottom-Up Code-Sharing with Kotlin Multiplatform

on YouTube ↗40m

" summary

Kotlin Multiplatform is shown moving from idea to running code: a sample project computes sunrise and sunset with a core module that has two public functions for sun and noon times, avoids external deps, and uses degree↔radian utilities. Platform edges use expect/actual declarations, SQLDelight for persistence, Ktor client and coroutines for networking and async, and Kotlin/Native worker freezing causes threading pitfalls. An iOS app and calendar image renderer are built, XcodeCompat Gradle plugin is used for Xcode integration.
