Kotlin Multiplatform is powerful, flexible, and full of promise—but it’s not all smooth sailing. Behind the glossy headlines and official documentation lie subtle bugs, platform quirks, and surprising limitations that can trip up even experienced developers. In this talk, we’ll take an honest look at the dark corners of Kotlin Multiplatform based on real-world usage. You’ll see concrete examples of things that break, don’t work as expected, or require strange workarounds—especially when working with Swift/Objective-C interop, background threading, dependency injection, or dealing with the iOS toolchain. You’ll learn: - What breaks and why in real apps using KMP - Debugging tips and stack trace decoding (especially on iOS) - Build issues, performance bottlenecks, and memory management caveats - Workarounds that are ugly, but necessary—for now This is not a “KMP is bad” talk. It’s a “here’s what to expect when you go beyond the tutorial” talk—ideal for anyone already using Kotlin Multiplatform or seriously considering it for production.
