Has anyone given formal workshops at work to train their team on Kotlin? Do most people just follow the Koans or does anyone know of some opensource lesson materials to use?

I put together a collection of YouTube resources for the team to watch. I also made a sample project focused on teaching the differences between the scoping functions.

👍 nice. Yes I definitely wanted to spend some practical sample time on stdlib and run/let/apply/with/etc

The best way to learn though is to make stuff in Kotlin.

ha wow. This is the first I'm hearing of an Android dev who doesn't want to jump off the Java ship right away 🙂

Hey Andy - I work for Big Nerd Ranch and we teach Kotlin for both our corporate partners and anyone who can get to Atlanta for our Open Enrollment training. It's a rigorous two day course (or seven day course combined with our Android Essentials class): https://www.bignerdranch.com/training/bootcamps/

@dewildte could you please share playlist of videos?

Android studio has a learn kotlin plugin that really good

This. Throwing people into the deep end (letting them start with writing Java in Kotlin) while showing them various Kotlin "tricks" gradually over time is how I got most of my team on board and they love the language.

Yeah I think my team is at the writing Java in Kotlin level for the most part. Most of them have already done the Big Nerd Ranch training @myotive
