Does this skill provide code for both Android and iOS?

Yes, it includes standardized patterns and code snippets for both Android (Kotlin/Java) and iOS (Swift/Native) implementations.

What is the expect/actual pattern in KMP?

The expect/actual pattern is Kotlin's mechanism for defining a common interface in shared code (expect) and providing platform-specific implementations (actual) for targets like Android and iOS.

When should I use the expect/actual skill?

Use this skill whenever you need to access platform-specific APIs—such as the camera, secure storage, or file system—from within a shared Kotlin Multiplatform module.

Can I use these patterns for KMP Desktop or Web?

While the primary focus is mobile, the expect/actual patterns provided are universal and can be adapted for Desktop (JVM) and Web (JS/Wasm) targets.

Implements platform-specific logic in Kotlin Multiplatform projects using standardized expect/actual declaration patterns.

This skill equips Claude with the domain-specific knowledge required to implement Kotlin Multiplatform (KMP) expect/actual patterns effectively. It provides templates and best practices for bridging shared code with platform-specific APIs, such as Android's Build versioning or iOS's UIDevice. By following these patterns, developers can maintain a clean shared API surface in commonMain while leveraging native capabilities for file systems, secure storage, network monitoring, and databases across Android, iOS, and desktop targets.
