As Kotlin Multiplatform (KMP) grows, the challenge moves from sharing simple utility code to handling complex data layers across Android, iOS, Desktop, and Web. GraphQL provides a type-safe and efficient solution for modern APIs. With Apollo Kotlin’s strong multiplatform support, developers can now share all their networking and data logic.

In this session, we will focus on how to implement Apollo GraphQL in a KMP architecture. Using our experience in building scalable Android apps with Jetpack Compose, we will look at how to apply those skills in a multi-platform setup.

Key takeaways include:

- Architecture: Setting up a shared data module that serves Android (Compose), iOS (SwiftUI), and Desktop.

- Type-Safety: Using Apollo’s code generation to keep a single source of truth for your API schema across all platforms.

- Best Practices: Managing caching, authentication headers, and reactive queries with Kotlin Coroutines and Flow.

- Real-world hurdles: Handling platform-specific configurations and improving network performance for a consistent user experience.
