Building apps using Kotlin Native
summary
Practical walkthrough of using Kotlin Native to share business logic across Android and iOS: compiler via LLVM produces an Objective‑C framework imported by CocoaPods using a Gradle task, Kotlinx.serialization + Ktor (iOS engine = NSURLSession) handle JSON and HTTP, SQLDelight generates SQLite code, and tests compile/run on each platform. Concurrency relies on workers, freezing and atomic references and can throw runtime capture errors. Examples include GitNotes and Yava; recommendation: expect/actual for platform APIs, Gradle → CocoaPod integration, Kotlinx.serialization for models.
