Covers creating type-safe and thread-safe wrapper types (SuspendWrapper and FlowWrapper) in Kotlin's iosMain source set, handling freeze() calls for Kotlin/Native thread safety, and writing Swift top-level functions that convert these wrappers into RxSwift Singles and Observables. Also addresses generic type erasure limitations when extending Objective-C generic classes in Swift, error propagation via a KotlinError wrapper, and cancellation linking between Rx disposables and coroutine Jobs. ## Full article daily.dev links to this article rather than hosting it.
