Mobile Development with Kotlin Multiplatform

Introduction

The book "Kotlin Multiplatform Mobile Development" (Pamela Hill, 2022, 282 pages) is a practical guide to creating cross-platform mobile applications using Kotlin Multiplatform Mobile (KMM) technology. In an era where companies seek to reduce development costs for iOS and Android, KMM offers an elegant solution: write business logic once in Kotlin, and UI natively for each platform. The author, Pamela Hill, a renowned Kotlin evangelist and developer, shares her experience and proven patterns.

What the book is about

The book covers the full cycle of creating a KMM project: from environment setup to publishing in app stores. The main focus is on modular architecture, organizing shared code (shared module), and integrating with platform APIs. Topics covered include:

• Setting up Gradle modules for KMM
• Creating shared code for network requests (Ktor), serialization (kotlinx.serialization), and data storage (SQLDelight)
• Using expect/actual for platform implementations
• Testing shared code and UI components
• Working with Compose Multiplatform for creating shared UI
• Integration with native frameworks (SwiftUI, Jetpack Compose)
• CI/CD and deployment
