Lately I've been feeling like my Android project was taking way longer to build (around 2 mins, when it used to build in less than a minute for sure). I'm running Android Studio for arm64, with java processes running on Apple Silicon architecture (checked in the Activity Monitor).
In case anyone runs into the same problem, it turns out the slow down occurred after updating to Kotlin 1.6.0 (hence the title of the question). I updated the Kotlin version of my project to the Kotlin plugin version in my Android Studio, which was 1.6.10 and the build time went from 2 mins to 20 seconds, when changes where applied.
