105: Jake Wharton on the Android Kotlin Guides

In this episode, we talk to Jake Wharton of Google on a recent Kotlin coding style guide that they released: the Android Kotlin Guides. In this episode, we pick his brains and ask him how he structured the guide, how he partitioned it to fit some of the idiosyncrasies of Kotlin, what some of the challenges were, when coming up with the guide and much more.

Jake's one of the best out there and it's always such a pleasure to have him on the show. Listen on:
