The State of Kotlin
summary
Kotlin reaches 1.9 now and a rewritten K2 compiler targets Kotlin 2.0 next year promising faster compilation and smoother migration. Android adoption is high — 95% of top Play Store apps use Kotlin and Compose appears in 23% of apps. JetBrains ships Ktor (coroutines‑powered) for server work, Kotlin Multiplatform shares serialization, networking and data models across JVM, native and JS, and Compose Multiplatform is desktop‑stable, iOS‑alpha and web‑experimental.
