Kotlin Multiplatform From “Hello World” to the Real World

on YouTube ↗39m

" summary

Kotlin Multiplatform is usable in production (beta) and is used at Touchlab since pre‑alpha; Android and iOS targets are the focus with KMM plugin templates for quick experiments and a CampKit sample for a real‑world repo. Teams publish Kotlin Native artifacts instead of monorepos, use Camembert Gradle plugin to ease iOS publishing to CocoaPods or SPM, and limit public API surface to reduce Objective‑C bridge bloat. Common patterns: Flow->LiveData wrappers for viewmodels, NWConnection and platform socket adapters, and the paid Sky tool for smoother Swift/Kotlin interfaces.
