Kotlin Native 0.4 is out since the beginning of November and, with it, some nice sample iOS demo apps to be run into your favourite iOS device. That sounds amazing, even for some hardcore Swift fans like me. Yet, there’s a catch: the sample apps can only run on a real iOS device but not in the Simulator.
