I’m excited to share this article on how to use Swift libraries or Swift code in your Kotlin Multiplatform (KMP) project—with simple, easy-to-follow steps 🎯🍏🤖. I would like to have a feedback on where can i improve it and so. https://pnbharat.medium.com/kmp-x-swift-how-to-use-swift-libraries-in-kotlin-multiplatform-with-google-sign-in-as-example-208f18b3c3d6

Hello everyone, I have just updated my Swift Macro KTViewModelBuilder to full Swift 6 compatibility. • The macro helps you to remove a lot of boilerplate on using the KMP ViewModel with SwiftUI. Give it a try 🙂

How to correctly make blocking calls in Kotlin Coroutines? It might suprise you, but IO dispatcher is not the best answer! Learn about it in this new article by @marcinmoskala. https://kt.academy/article/interop-blocking-to-coroutines

Hi Folks, a new release of Signum is ready! It introduces the last building blocks for baseline feature completeness: RSA encryption and KDF/KSF. Certificates now support arbitrary signature algorithms, and we also revamped the ASN.1 engine's decoding API. Since this release is based on kotlinx.datetime 0.7.1, there were some API changes that go along with this migration. We used this opportunity to also rework Known OIDs, so update your imports. Last time, I teased that we were approaching feature completeness and that we wanted feedback. Sometimes you get what you ask for: there is apparently more demand for extensibility beyond the algorithms shipped with Signum than we anticipated (even on mobile targets). Hence, we will allow future Signum versions to be extended with arbitrary algorithms and the provider will support more targets. It comes with a caveat, though: there is no way to do this without invasive changes (from enums to open classes; from hardwired sets of signature algorithms to enabling full cryptographic agility). Hence, we will be dedicating our resources to rewiring lots of parts over the next few months, and we'll migrate to new coordinates and a new versioning scheme to indicate this fundamental change. The only part where we expect minimal changes is the ASN.1 engine, since this part really is battle-tested after serving millions in production. Some new functionality is still expected to hit the current incarnation of Signum until then, but nothing major.

Hi everyone, Today I released Decoroutinator version 2.5.5 - a library for recovering stack trace in Kotlin coroutines. This release contains some fixes and performance improvements.

Early this week because last week didn’t happen because stuff

Elide, the Kotlin-native runtime and build toolchain, has released 1.0.0-beta8, with many bugfixes and new support for Kotlin Power Assert and MCP! Elide is a Node or Python-like runtime (a binary on your machine), which is an end-to-end toolchain and runner: • JavaScript, TypeScript, Python, Kotlin, Java, all in one runtime • Powered by insanely good engine from GraalVM • Install Maven dependencies • Run tests without hassle; easy coverage and other features In this release we also added MCP integration, and a website builder. MCP integration lets tools like Claude Code interrogate your project. AI agents automatically know where your code is, how to build it, and how to run tests. It's pretty cool! We are all Kotlin authors ourselves and so this community is very close to our hearts. If you have feedback or ideas, come join our Discord and tell us. We'll build them! Star us on GitHub ⭐ and see below for demos 👇 🧵 https://github.com/elide-dev/elide/releases/tag/1.0.0-beta8

Just tagged v1.38.1 of Compose Unstyled! 🎹 Made Sheets keyboard aware (opt-in) ⚡️ Dynamic Sheet detent support 🔘 New outline modifier (!!!) and more Docs: https://composables.com/docs/com.composables/core Change log: https://github.com/composablehorizons/compose-unstyled/releases/tag/1.38.0

Hi 👋 I've just released version

1.4.0

of my library Boomerang - navigation result framework for Compose Multiplatform and Androidx Fragments In this release I've added experimental support for Kotlinx Serialization (only flat non-nested objects are supported for now) and some QOL support funcions. Check out and let me know what you think 🔥 https://github.com/buszi/Boomerang/releases/tag/1.4.0

Curious what a 100% Kotlin Alexa Smart Home Skill looks like under the hood? 🛠️ Check out the source code here: https://github.com/StefanOltmann/smart-home-alexaskill I've been running this skill in production in my own smart home for years, and just gave it a solid update with the latest libraries and a cleaner structure. If you're into smart home development, you might find it interesting! 🙂

Yesterday, I discovered the Kotlin/Native Runtime for AWS Lambda by Viacheslav Ivanovichev and decided to give it a try. I ended up creating a fully Kotlin/Native version of my Smart Home Alexa Skill: https://github.com/stefanoltmann/smart-home-alexaskill-native And what can I say? I'm genuinely impressed. With the Java-based Lambda, processing a voice command like “_Alexa, turn off the bedroom lights_” typically took 3–5 seconds when cold (and 500 ms when warm). I always considered that normal and just lived with it for years. Now, with the Kotlin/Native version, from a cold start it takes just 350 ms to process the command — and when warm it is down to 130 ms. That's just awesome. 🙂

When Tool-Calling Becomes an Addiction: Debugging LLM Patterns in Koog I was testing my agent built on Koog, JetBrains’ open-source framework for building AI agents in Kotlin. I fed it a task from SWE-bench-Verified, a real-world GitHub issue that tests whether AI can actually write code. For the first 100 messages, everything looked promising. The agent methodically explored the codebase, identified bugs, wrote test cases, […]
