Recording brought to you by American Express. https://americanexpress.io/kotlin-jobs Over the past year, Multiplatform Fever has swept the world with the promise of code sharing between iOS and Android codebases. But how does it *really* work? What compromises have to be made by both platforms in order to achieve this goal? This talk will make a deep comparison of #Swift vs. Kotlin, you'd need a deep understanding of both languages Some topics that would be covered: * How do Swift consumers interact with Kotlin code (for example, generics) * What problems does ObjC bring to the table? * Fundamental differences between Swift and Kotlin today (value types/structures vs data classes, enums with associated values vs sealed classes) * Performance implications (build and runtime) * Current problems + best practices to avoid them Attendees will leave this talk with a better understanding of what problems still exist, yet feel encouraged to start dabbling in their current codebases.
