Kotlin Multiplatform Newsletter #8
Reduced Play Store fees for app developers, deep-dive into architecture wars regarding KMP ViewModels, cross-platform & open source 2FA app, useful Compose Multiplatform libraries and a job opportunity at Touchlab.
The Log
The only Kotlin Multiplatform and Compose Multiplatform news you actually need to know.
Today we are announcing substantial updates that evolve our business model and build on our long history of openness globally. We’re doing that in three ways: more billing options, a program for registered app stores, and lower fees and new programs for developers.
Expect Actual
Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems.
Practical Kotlin Deep Dive (Jaewoong Eum) takes you beneath the surface of Kotlin, exploring not just what the language does, but how it works and why it was built that way.
From foundational concepts through coroutines, compiler architecture, and Kotlin Multiplatform, this book connects everyday coding patterns to their underlying mechanisms.
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 and Android.
In this article, I’ll walk through the “Pure Kotlin ViewModel” pattern I used to keep shared ViewModels platform-agnostic, how I bridged them to SwiftUI using explicit wrappers, and how this approach compares to newer, library-driven alternatives in the evolving KMP ecosystem.
The internet is full of tutorials on how to fetch data from an API and display it in a UI. But very few show you what happens when the network suddenly vanishes mid-operation and what an app that handles that gracefully actually looks like under the hood.
