Join Adrian Catalan and Cecilia Castillo to see an Android developer doing Swift, an iOS developer writing Kotlin, and enjoy this thrill ride with two tour guides that will drive you out of your comfort zone while sharing their struggles and success to inspire you to learn the languages. You'll gain a better understanding of how to start using the other language once you've taken your first steps on one.
