(Article) Introduce cross-platform mobile development to your team I really liked this article about introducing new technology in teams because it has a really holistic approach. It starts with empathy for each member of the team that has to undergo some discomfort and change to adopt something new. This cannot be overstated - this is can make or break your efforts. It then moves to the more practical aspects and gives advice on how you approach these points.
(Videos) Kotlin multiplatform mobile playlist The official video guide to getting started if you are a watch-and-learn, rather than a read-and-learn person. This tutorial series will help you start by setting up your environment, creating a simple application, and then a more complicated one. It also contains information about what's the latest news on Kotlin Multiplatform Mobile, so I expect updates will also be posted there in future.
(Video) Talking Kotlin: Why iOS developers at Todoist wanted Kotlin Multiplatform An interview with Goncalo Silva, CTO from Todoist on how and why iOS developers on their teams were actively looking to adopt Kotlin Multiplatform Mobile. Really nice interview to make your iOS developers interested in their viewpoints.
Books
Simplifying application development with Kotlin Multiplatform Mobile (1st ed.) by Robert Nagy This was my first book and a good introduction to Kotlin Multiplatform Mobile. Having done more research and had more conversations I feel that there's so much more that was simply glossed over. It's also a little out of date by now.
Kotlin Multiplatform by Tutorials by Ray Wenderlich tutorials team Instead, I would recommend this book by the publisher Ray Wenderlich. I found it to be much more informative than the previous version, and I liked that it had a much broader range of topics taking you from beginner to intermediate and advanced Kotlin Multiplatform Mobile knowledge.
Blog articles
