A big thanks to every student who attended this session. Thanks to Mr. Richard Joseph who was kind enough to introduce me to the students and faculty. This talk went wonderfully and students who never knew Kotlin were able to grasp the concepts easily. We had a small Q&A at the end of day one. With this introductory session on Kotlin the students are now prepared to build their very first Android app!
