Shows concrete, battle‑tested patterns from five years of KMP/CMP projects: expect/actual examples that build working iOS frameworks, an ISS map demo that composes with SwiftUI, and concrete fixes for mapping/cancellation gaps. Covers sky framework and KMP native coroutines for proper concurrency interop, Compose UI view controller and UIHostingController glue for CMP ↔ SwiftUI, Maestro tests, XCFramework/SwiftPM packaging and Xcode Kotlin debugging. Explains which defaults fail (sealed classes, cancellation) and which libraries reliably fix them.
