Introduction

In Lesson 1, you learned how Swift business logic integrates with Kotlin UI through automatic Java bindings. Your Task Manager validates tasks using Swift, demonstrating basic data flow between languages.

In this lesson, you’ll add photo capture and image processing to the Task Manager. You’ll integrate Android’s CameraX with Swift image filters, demonstrating bidirectional data flow where data travels from Kotlin to Swift and back. You’ll work with binary data marshaling, implement pixel-level image filters, and understand the complete roundtrip across the language boundary.
