Unlock the true power of Kotlin to write once and run everywhere. In Kotlin Multiplatform Development, veteran software architect Stokes J. Harrett shows you step-by-step how to share business logic across Android, iOS, Web, and Desktop—without sacrificing native performance or user experience.
Why This Book Matters
• Maximize Code Reuse: Master Kotlin Multiplatform (KMP) to consolidate networking, data models, and business rules into a single, maintainable codebase.
• Native-Level UIs: Leverage Jetpack Compose Multiplatform for Android and Desktop, Swift/SwiftUI for iOS, and Compose for Web—delivering truly native interfaces on every platform.
• Robust Toolchain: Integrate industry-leading libraries—Ktor for networking, SQLDelight for local storage, Koin for dependency injection, and kotlinx.serialization for seamless data parsing.
What You’ll Build
Cross-Platform Mobile Apps: Combine shared Kotlin logic with Android Studio and Xcode tooling.
Responsive Web Interfaces: Utilize Kotlin/JS and Compose for Web to develop interactive browser applications.
Desktop Applications: Create JVM-based desktop apps using Compose for Desktop and native packaging.
Full-Stack Sync: Implement offline-first data caching and cloud synchronization with Ktor backends.
Key Features & Benefits
Clean Architecture & Modular Design: Organize code into domain, data, and presentation layers for maximum testability and scalability.
Expect/Actual Abstractions: Harness Kotlin’s expect/actual mechanism to bridge platform-specific APIs—camera, file I/O, notifications—while keeping shared code platform-agnostic.
Comprehensive Testing Strategy: Build unit and integration tests that run across JVM, Native, and JS targets using kotlin.test, MockK, and Ktor’s MockEngine.
CI/CD and Publishing: Automate builds, tests, and artifact publishing to Maven Central and CocoaPods with Gradle and GitHub Actions.
