We dive deep into practical multiplatform mechanics, including a step-by-step roadmap for publishing your KMP library to **Maven Central**, integrating a robust **WebView** across Android, iOS, and Desktop, and migrating past the deprecated `PredictiveBackHandler` in Compose Multiplatform 1.10.x. Plus, we explore **KMPify** for automated project migrations and highlight a senior KMP opening at Yazio. ### **The Log** The only Kotlin Multiplatform and Compose Multiplatform news you actually need to know. [KMP Contest Starter Kit 2026 Grant Recipient](https://kotlinfoundation.org/news/kmp-contest-starter-kit-2026-grant-recipient/?ref=commonmain.dev) The Kotlin Foundation team responsible for evaluating the submissions was genuinely impressed by the thoughtfulness of the submissions and shares a heartfelt thank you to everybody who took the time to share their ideas of what a compelling KMP Contest Starter Kit would look like. [JetBrains Developer Ecosystem Survey 2026](https://surveys.jetbrains.com/s3/cn-developer-ecosystem-survey-2026?ref=commonmain.dev) Take part in the 10th annual JetBrains Developer Ecosystem Survey! Your insights are essential. They help us map the state of software development and shape the industry report we’ll publish from the aggregated results. [Official Kotlin Support for Visual Studio Code Is Now Available in Alpha](https://blog.jetbrains.com/kotlin/2026/05/official-kotlin-support-for-visual-studio-code-is-now-available-in-alpha/?ref=commonmain.dev) IntelliJ IDEA and Android Studio remain the most complete environments for Kotlin development. But not every Kotlin developer uses either IDE – some prefer VS Code. Kotlin by JetBrains is an extension for those developers, providing official Kotlin language support in VS Code, powered by the Kotlin Language Server, and offering core features for reading, writing, and navigating Kotlin code. ### Expect Actual Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems. SPONSORED ****Stop treating Kotlin like a black box! 🧠** To build truly performant multiplatform apps, writing code that just "works" isn't enough. We need to understand what the compiler is actually doing under the hood. That’s why I highly recommend [****Practical Kotlin Deep Dive**](https://skydoves.gumroad.com/l/kotlin-deep-dive?a=705284499&ref=commonmain.dev) by skydoves. This isn't a basic syntax guide, it breaks down Kotlin internals, bytecode, and coroutines. It’s been a total game-changer for me when writing and optimizing shared code. If you want to level up your Kotlin and KMP skills to a senior standard, you need this on your desk. [Get the Book ](https://skydoves.gumroad.com/l/kotlin-deep-dive?a=705284499&ref=commonmain.dev) [Homologated: Publishing Your Kotlin Multiplatform Library to Maven Central](https://www.kmpbits.com/posts/kmp-maven-central?ref=commonmain.dev) Publishing a Kotlin Multiplatform library to Maven Central is your homologation moment. Until you do it, your library is a `mavenLocal()` entry that only you can use. After it, anyone can add one line to their `libs.versions.toml` and pull it in without cloning anything. [Kotlin Context Parameters: Cleaner and Safer APIs](https://bloder.io/kotlin-context-parameters?ref=commonmain.dev) Kotlin keeps getting better at expressing intent in the type system. One of the most interesting language proposals right now is Context Parameters, a redesign of the earlier context receivers idea. [Adding a WebView to Compose Multiplatform: Android, iOS, and Desktop](https://medium.com/@rwatson%5F86305/adding-a-webview-to-compose-multiplatform-android-ios-and-desktop-8f17e91649f4?ref=commonmain.dev) This article walks through a working implementation that covers all three platforms. The focus is on the decisions that required real investigation — not the parts that follow directly from reading the API documentation, but the parts where the documentation is silent and the behavior is only understandable after tracing through what is actually happening. ### LazyColumn Compose Multiplatform tips, tricks, and code snippets. [KMPify](https://github.com/MahmoudRH/kmpify?ref=commonmain.dev) KMPify is a Kotlin tool that helps migrate Android Jetpack Compose projects to Kotlin Multiplatform (KMP) with minimal effort. Available as both a CLI tool and Desktop GUI. [Goodbye PredictiveBackHandler: How to Migrate to the New Navigation Event in Compose](https://medium.com/@santimattius/goodbye-predictivebackhandler-how-to-migrate-to-the-new-navigation-event-in-compose-6e2f294f5ddb?ref=commonmain.dev) If you work with ****predictive back** in Compose and have updated to Compose Multiplatform 1.10.x, your code likely no longer compiles. This isn’t a bug: `PredictiveBackHandler()` has been deprecated, and the new API changes how you model the “back” gesture. In this article, I’ll explain what changed, why, and how to migrate step by step. ### The Dependency Graph Curated libraries, tools and plugins that won't break your Gradle build. - [**Kottie**](https://github.com/ismai117/kottie?ref=commonmain.dev) Compose Multiplatform animation library that parses Adobe After Effects animations.
