Kodee’s Kotlin Roundup: Compose Multiplatform for iOS is Stable (Plus AI, Web, and More!)

A fresh Release Candidate is out with Kotlin 2.1.21-RC2, bringing bug fixes and performance boosts to 2.1.20. It’s a behind-the-scenes kind of update, but your builds might feel a little snappier.

Kotlin 2.2.0-Beta2 has also landed with a handful of improvements:
– Kotlin compiler: unified management of compiler warnings.
– Kotlin/JVM: changes to default method generation for interface functions.
– Gradle: integration of Problems API within KGP diagnostics and KGP compatibility with ‘–warning-mode’.
