The Definitive Guide to Kotlin Multiplatform Projects
Kotlin Multiplatform (KMP) promises shared business logic across Android, iOS, web, and desktop, but many teams struggle with integration, tooling, and common pitfalls. This guide cuts through the hype to provide a practical, problem-focused roadmap: from understanding how KMP actually compiles and shares code, to setting up a real project structure, navigating the ecosystem of libraries and build tools, and avoiding the mistakes that derail production adoption. We cover the trade-offs between KMP and traditional cross-platform approaches like Flutter and React Native, and offer concrete steps for incrementally introducing KMP into existing codebases. Whether you are evaluating KMP for a new project or trying to fix a struggling shared module, this guide gives you the decision criteria and hands-on advice you need to succeed.
