SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill addresses the challenge of writing and maintaining separate codebases for different platforms (Android, iOS, etc.) by enabling the sharing of common logic, reducing development time and ensuring consistency.

Core Features & Use Cases

Shared Logic: Define and implement business logic, data layers, and utilities once for use across multiple platforms.
Platform Integration: Seamlessly integrate shared code with platform-specific UI and APIs.
Use Case: Develop a mobile application where the networking, data storage, and core business rules are written in Kotlin Multiplatform, while the UI is built natively for Android (Compose) and iOS (SwiftUI).

Quick Start

Use the Kotlin Multiplatform skill to set up a shared module for your Android and iOS applications.
