Calling Kotlin Multiplatform Coroutines from Swift with the help of KMP-NativeCoroutines
summary
Demo app uses Kotlin Multiplatform plus the KMP-NativeCoroutines Gradle plugin to expose suspending functions and flows to Swift as native APIs with no nullable wrappers, fixing generic loss for flows. It generates async/await and Combine friendly bindings, supports AsyncSequence, and demonstrates automatic cancellation when views deinit. Exception handling still requires try/catch because unhandled Kotlin exceptions crash the app. The repository and examples (suspend returns true/false, flows emit 0 1 2 then throw) compile and behave as shown.
