Kotlin Multiplatform Samples
This repository provides a collection of reference implementations for building mobile applications using the Kotlin Multiplatform framework. It serves as a practical guide for centralizing core application logic, data handling, and business rules into a single shared codebase while maintaining the ability to build native user interfaces for Android and iOS.
The project demonstrates architectural patterns for managing state, persistence, and network synchronization across diverse mobile operating systems. By utilizing common source sets and platform-specific native interop, it enables developers to share code effectively while still accessing platform-native APIs and libraries. The samples illustrate how to maintain consistent application behavior and data integrity across different environments without duplicating development effort.
The included examples cover a broad range of mobile development tasks, including local relational database management, key-value preference storage, and reactive data stream handling. The repository also highlights workflows for debugging cross-platform code, previewing visual components, and accelerating iteration cycles through live code updates.
Features
- Mobile Development - Serves as a comprehensive reference implementation for building mobile applications using a shared Kotlin codebase.
- Cross-Platform Application Development - Builds mobile software for multiple operating systems using a single codebase to reduce development effort.
- Native Platform Access - Exposes native platform APIs to shared code through language-level bindings for direct interaction with host operating systems.
- Native Cross-Platform Development - Utilizes a unified approach to building high-performance applications for multiple mobile platforms from a single codebase.

- Mobile Application Architectures - Defines structural patterns and design principles for managing state, persistence, and synchronization in mobile applications.
- Development Iteration Workflows - Reflects code changes instantly in the running application during development to accelerate the iteration cycle.
- Cross-Platform Synchronization Services - Provides mechanisms for synchronizing application state and data across multiple mobile client applications and devices.
- Target Compiler Mappings - Maps common language constructs to native targets during the build process to generate platform-specific binaries.
- Reactive Data Streams - Propagates state changes across platform boundaries using non-blocking streams that notify the user interface of updates in real time.
- Lifecycle-Aware State Holders - Maintains application data across configuration changes by hooking into native platform lifecycle events.
