Congratulations! You’ve just built a hybrid Android application using Swift SDK for Android. By combining Swift’s business logic with Kotlin’s native UI, you’ve created a Task Manager app that leverages the strengths of both languages.

Key Takeaways

  • Swift SDK for Android enables you to write Swift code that runs natively on Android devices
  • The swift-java library with JExtractSwiftPlugin automatically generates Java bindings from your Swift code, eliminating manual JNI work
  • The three-layer architecture separates concerns: Kotlin/Compose for UI, auto-generated bindings for interoperability, and Swift for business logic
  • Swift’s value types, strong type safety, and explicit error handling make business logic more robust and maintainable
  • Gradle integration automates the entire workflow - from Swift compilation to Java class generation to APK building
