Good updates and nice progress so far . Thank You 👏

Just wanted to share a personal observation: for mid- and large-scale projects (CMP mobile apps), generating an xcarchive for iOS distribution is still a challenge. It always runs into OOM (out-of-memory) issues and blocks xcarchive creation — even on a Mac M4 with 24 GB RAM.*

👉 This happens even after setting max heap memory in Gradle commands and enabling all meta/Gradle property options.

This becomes a release blocker once development is done. If anyone has tips, workarounds, or insights on optimizations for this, would love to hear and learn from your experience 🙏

GitHub Action for KMP library without iOS: 5 to 10 minutes.
Add iOS & macOS targets: 45 to 60 minutes.

Yeah, could need some work. 😄

Tried in M4 , 24 GB RAM
Almost ~3 Hours waited for iOS but no luck.

[Stefan Oltmann]

What a minute... all this time this was a alpha version? 🫣
I use that in every production app. 😅

[Stefan Oltmann]

Overall a great roadmap! K🚀🙂

At the bottom of the Kotlin Multiplatform section there's a link to https://jb.gg/kmp-roadmap-2025 which 404s
Looks like this is fixed now

Love the effort put into providing language server for kotlin 🙂

[Sargun Vohra]

The Kotlin language server was huge for me prototyping MapLibre Native integration with the JVM using LLMs to help me through the bits I was less familiar with (graphics APIs). After prototyping though, I had to go back to no LSP to port the prototype to my KMP library's desktop target.

Looking forward to a future update supporting KMP projects.

[Tian Tian098]

With Java 25's imminent release, will Kotlin continue to integrate with new and future Java features? I would love to see a blog post about this.

no rich errors in kotlin 2.4 beta?
