One Codebase, Every Platform: Kotlin Multiplatform in Production: Sharing Business Logic Across iOS, Android, and Web

Building applications for multiple platforms often means maintaining multiple codebases. The result is duplicated logic, inconsistent behavior, slower development cycles, and higher maintenance costs. "Kotlin Multiplatform in Production" is a practical, engineering focused guide to building cross-platform applications with shared business logic using Kotlin Multiplatform. This book teaches you how to maximize code reuse while preserving the native experience users expect on every platform. Why Kotlin Multiplatform ... Read More

Building applications for multiple platforms often means maintaining multiple codebases. The result is duplicated logic, inconsistent behavior, slower development cycles, and higher maintenance costs. "Kotlin Multiplatform in Production" is a practical, engineering focused guide to building cross-platform applications with shared business logic using Kotlin Multiplatform. This book teaches you how to maximize code reuse while preserving the native experience users expect on every platform. Why Kotlin Multiplatform matters Modern teams must support: iOS applications Android applications web experiences backend services Maintaining separate implementations for every platform can quickly become expensive and difficult to scale. Kotlin Multiplatform allows teams to: share core business logic reduce duplicated code improve consistency across products accelerate feature delivery maintain platform specific user experiences This book shows how to achieve these benefits in real production environments. What you will learn fundamentals of Kotlin Multiplatform architecture structuring shared and platform specific code sharing business logic across applications networking and API integration patterns local storage and data synchronization dependency injection strategies testing shared modules effectively performance optimization techniques deployment and release workflows scaling large cross-platform codebases From separate apps to unified engineering Throughout the book, you will learn how to: design maintainable shared modules reduce duplication across teams build reusable domain and data layers integrate platform specific capabilities cleanly improve development velocity maintain production quality across platforms Each chapter focuses on practical software engineering workflows used in modern cross-platform teams. Practical applications consumer mobile applications SaaS companion apps enterprise mobile platforms shared business logic libraries multi-platform product ecosystems cross-platform startup applications These examples reflect real world software development challenges. Who this book is for Kotlin developers Android engineers iOS developers exploring shared architecture mobile engineering teams software architects organizations managing multiple platform applications If you want to build applications that share code intelligently while maintaining native quality, this book provides the roadmap. Share logic once. Deliver everywhere. Scale development without duplication. Read Less
