Kotlin Multiplatform: Share Code Across iOS and Android

Building separate apps for iOS and Android often means writing the same business logic twice. Kotlin Multiplatform solves this by letting you share your core code while keeping your native user interfaces. This course guides you through the fundamentals of sharing code across platforms without sacrificing native performance. You will transition from understanding basic multiplatform concepts to structuring a shared codebase that powers both Android and iOS applications efficiently. What you'll learn: - Understand the foundational architecture of Kotlin Multiplatform and how shared code interacts with native platforms. - Configure a multiplatform project structure with shared modules and platform-specific implementations. - Write shared business logic using Kotlin Coroutines and Flow for asynchronous data management. - Implement multiplatform networking and data serialization using libraries like Ktor. - Connect shared code to native user interfaces, utilizing SwiftUI for iOS and Jetpack Compose for Android. - Apply the expect/actual mechanism to access platform-specific APIs when necessary. We begin with essential terminology and setup, establishing a solid conceptual foundation. From there, you will read through step-by-step explanations and code snippets that demonstrate how to structure shared libraries, manage state, and integrate with native platforms. This text-based course is designed for beginner mobile developers and programmers new to multiplatform development. No prior experience with cross-platform frameworks is required, though a basic understanding of programming concepts is helpful. Start reading today to streamline your mobile development workflow with a single, shared codebase.
