What's Next for Kotlin Multiplatform and Compose Multiplatform – August 2025 Update
Article Summary
Emil Flach from JetBrains just dropped the KMP roadmap through mid-2026, and it's packed with game-changers. If you're building cross-platform apps, this affects your next 12 months.
JetBrains has published their official 6-12 month roadmap for Kotlin Multiplatform and Compose Multiplatform. The update covers everything from iOS developer experience improvements to web target maturity, IDE tooling enhancements, and build system simplifications. This is the strategic direction for one of mobile's fastest-growing cross-platform frameworks.
Key Takeaways
- Compose Multiplatform for Web hitting Beta with production-ready APIs
- Swift Export reaching feature parity with Objective-C interop by 2026
- Kotlin/Wasm adding multi-module compilation for dynamic loading and better caching
- Windows and Linux getting full KMP IDE plugin support (minus iOS)
- Gradle getting project-level dependencies and declarative Kotlin DSL
JetBrains is systematically addressing KMP's biggest pain points: iOS build speeds, web target maturity, Swift interop quality, and Gradle complexity.
About This Article
Kotlin/Native builds are slow, and developers often misconfigure the kotlin.native.cacheKind property, which makes things worse.
JetBrains is testing performance improvements on real projects, making the compiler faster, and replacing kotlin.native.cacheKind with a more reliable option.
These compiler improvements and property changes should cut Kotlin/Native build times noticeably. That matters because slow builds are a real barrier to adopting Kotlin Multiplatform for iOS development.
