The Triumphs and Tribulations of Kotlin-Native in Practice

on YouTube ↗43m

" summary

Claim: Kotlin/Native compiles shared Kotlin to native via LLVM and can run on iOS and Android but demands many workarounds. Tools used: Gradle multi‑platform, Kotlin/Native via LLVM, Ktor client and kotlinx.serialization, Xcode interop that exposes Objective‑C headers. Built a server plus a Raspberry Pi–controlled deadbolt prototype that actually locks/unlocks from both apps. Surprises: coroutine dispatch differs (iOS uses NSURLSession on main thread), freezing object graph causes mutability exceptions, extensive Gradle version friction and manual Xcode linking.
