Kotlin: MAX PAYNE

on YouTube ↗46m

" summary

A team porting a mobile app to Kotlin documents concrete costs and fixes: nullability interop fails with unannotated Java APIs so they add an Option wrapper for Java nulls and custom adapters; kapt and annotation processors break incremental builds so they build a money-trainer remote build proxy to speed CI; Kotlin DSL causes Gradle/Kotlin version mismatches and plugins break; use of inline/const reduces method-call overhead; Spek tests and JUnit4→5 migration create fragile tooling; many bugs require filing Kotlin/YouTrack issues but runtime performance and developer ergonomics improve.
