Meanwhile, JetBrains announces the discontinuation of Swift language IDE support inside the KMP plugin. We also analyze iOS build time benchmarks (`Swift` vs `KMP`), architecting Free vs. Full product flavors in `commonMain`, running machine learning with **KTensorFlow 2.0**, and integrated FFmpeg video playback via **KitePlayer**. Plus, a remote Mobile Technical Lead opportunity at Accesa. ### **The Log** The only Kotlin Multiplatform and Compose Multiplatform news you actually need to know. [The State of Kotlin in 2026 Report](https://blog.jetbrains.com/kotlin/2026/09/state-of-kotlin-2026-report/?ref=commonmain.dev) In 2026, Kotlin turned fifteen. Over those fifteen years, Kotlin has built a mature ecosystem, been adopted by companies around the world, and established a large and active developer community. ****Key KMP facts:** \- Nearly 3% of the top 10,000 App Store apps by mid-2026 are using KMP, up from under 1% in early 2024\. Growing faster than Flutter and React Native. \- KMP apps in the top 10,000 match Flutter apps in total App Store revenue. \- 31% of Kotlin developers work on multiplatform projects. [Discontinuing Swift Language IDE Support in the Kotlin Multiplatform Plugin](https://blog.jetbrains.com/kotlin/2026/10/discontinuing-swift-language-ide-support-in-the-kotlin-multiplatform-plugin/?ref=commonmain.dev) Starting with IntelliJ IDEA 2026.3 and Android Studio Rabbit 2 | 2026.2.2, we’re discontinuing Swift language IDE features in the Kotlin Multiplatform (KMP) plugin. This includes editing, syntax highlighting, and navigation within Swift files and between Swift and Kotlin. ### Expect Actual Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems. affiliate link ****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) [The Companions to Come](https://blog.jetbrains.com/kotlin/2026/09/the-companions-to-come/?ref=commonmain.dev) We are working on extensions to our companions mechanism to unlock new code patterns and improve interoperability across different platforms. This post outlines these new features and provides preliminary guidance on migration. [Telemetry: Shared Analytics and Crash Reporting in Kotlin Multiplatform](https://medium.com/@kmpbits/telemetry-shared-analytics-and-crash-reporting-in-kotlin-multiplatform-kmp-bits-af77f81c153b?ref=commonmain.dev) In a modern endurance car, every sensor talks to the same box. Tyre pressure, brake temperature, fuel flow, throttle trace. They all end up in one data stream that goes to the pit wall over a single radio link. The engineer on the wall doesn’t care which supplier made the brake sensor. He cares that the channel is called `BRAKE_TEMP_FL` and that the number arrives every 100 milliseconds. Swap a sensor, the channel name stays. That’s the whole point of the standard. Analytics and crash reporting in a KMP app should work the same way. The sensors are the SDKs, one per platform, made by different teams with different APIs. The channel names are yours. [How I Built Free and Full Build Flavors for Android in My KMP Codebase](https://avik-sharma-chy.medium.com/how-i-built-free-and-full-build-flavors-for-android-in-my-kmp-codebase-511bffdcc28c?ref=commonmain.dev) This part is about how one codebase builds both versions: a free app with only the core features, and a full app with everything. I’ll cover product flavors, how the free app leaves the premium features out, and how the shared code works with either version without knowing which one it’s in. [Kotlin Multiplatform iOS build times: what's actually driving the cost](https://johnoreilly.dev/posts/kmp-ios-build-times/?ref=commonmain.dev) A recent article, [The Hidden Cost Behind Kotlin Multiplatform on iOS](https://kaanbiryol.com/the-hidden-cost-behind-kotlin-multiplatform-on-ios/?ref=commonmain.dev), looked at what KMP does to the iOS edit/build/run feedback loop. It’s a good question to ask and the article also comes with a benchmark harness ([kmp-ios-benchmark](https://github.com/kaanbiryol/kmp-ios-benchmark?ref=commonmain.dev)) that compares a Swift-only setup against an equivalent KMP one, using generated code across clean, incremental, public API change, multi-module and release builds. The headline numbers were that a single internal change rebuilt in 3.19s for Swift vs 10.36s for KMP, and that the gap grew with module size (KMP adding \~4.2x more time per 100 files than Swift). ### LazyColumn Compose Multiplatform tips, tricks, and code snippets. [Offline Support for Compose Multiplatform Web Apps](https://terrablog.pages.dev/blog/offline-support-compose-multiplatform-web-apps/?ref=commonmain.dev) When a user runs an app in a browser, it’s reasonable to assume they have an internet connection. But if a user has installed a PWA app and its icon is available on the desktop, it’s reasonable to expect it to behave like a native app when there’s no internet connection.
