Is AndroidX ViewModel the best choice for KMP projects? Sharing ViewModels between platforms affects the iOS developer experience. In this post we will discuss this topic and some possible solutions in KMP projects that respect the native feel of iOS...

🤔 Should ViewModels be shared across Android and iOS?

Or should the shared layer stop at business logic?

@faogustavo.bsky.social discusses the architectural trade-offs here 👉

Screenshot of the new agent tab in Gemini in Android Studio showing the input prompt and sample queries

The new agent in Android Studio is enabled in yesterday's canary build!

This build doesn't have all the tools hooked up that I showed in the I/O demo last week (agent here: youtu.be/KXKP2tDPW4Y?...), such as the Gradle awareness -- and it also doesn't have the Upgrade Agent yet. Hopefully soon!

We have a new episode of the ADB podcast up, this time covering KMP -- Kotlin multiplatform. Yigit Boyar (@yboyar.bsky.social), Dustin Lam and I discuss library support, developer experience and a lot more. I found it fascinating, but Yigit's dog fell asleep...

Kotlin Multiplatform Tooling – Shifting Gears | The Kotlin Blog A couple of years ago, we initiated the idea of creating a Kotlin Multiplatform IDE to help facilitate the development of KMP applications. We embarked on this venture, building on the Fleet platform,

Original post is removed. Blog post still up blog.jetbrains.com/kotlin/2025/...

Am I allowed to use the pun: good IDEA?

Fleet is a good idea for JetBrains quality tooling with polyglot programming capability to compete with VSCode. Especially for #KotlinMultiplatform where you switch between Kotlin and Swift (and maybe Java and Obj-C and JS and C ...). But it's not IDEA 😉

🚀 #KMMBridge 1.2.1 is here!

What’s new?
✅ Publish CocoaPods artifacts via GitHub Releases
✅ Better error logging for faster debugging
✅ Smoother #KMP-to-iOS workflow

@kevinschildhorn.bsky.social breaks down all the updates here 👇

Yes ! We recently made androidx.traceprocessor KMP available. So you should be able to emit traces and use Trace processor to assert for them. That's one of the things I want to demonstrate.

The #KotlinMultiplatform train never stops at Google. Incredible to see the continuing #KMP experiments from the #Android team

Drawing of how WASM's workflow can work from a variety of languages, to many outputs

Some of you know that I lead many Core infrastructure teams at Google, and one of those teams is Multiplatform development.

As such, I've been extremely interested in WASM lately- you've probably heard about WASM's benefits for performance, but did you also know WASM is great at *portability*?

Kermit is an essential library for the KMP ecosystem so we take user feedback seriously. However, we don't make money off our open source work so need to triage pretty heavily. The more upvotes in discussions, the more priority we give github.com/touchlab/Ker...
