Discover how to leverage Swift’s safety features and expressiveness for Android development with Swift SDK for Android. This comprehensive module teaches you to build hybrid Android applications where Swift handles business logic and Kotlin manages the UI with Jetpack Compose. Through three hands-on lessons, you’ll build a Task Manager app that showcases Swift-Java interoperability. You’ll start with basic validation using swift-java and JExtractSwiftPlugin for automatic bindings, progress to platform integration with CameraX and image processing, and complete the course with data persistence and comprehensive testing. By the end of this course, you’ll understand how to use Swift’s type safety, powerful error handling, and modern language features within Android projects giving you the best of both ecosystems without writing manual JNI code.

Swift-Java Interoperability: Building the Task Manager Core Lesson (57 mins)

Learn how to use Swift SDK for Android to build a Task Manager app where Swift handles data validation and business rules while Kotlin manages the native UI with Jetpack Compose. You’ll install swiftly, create a Swift package, set up swift-java with JExtractSwiftPlugin, and connect Kotlin to Swift through auto-generated bindings.

Platform Integration: Camera & Image Processing Lesson (58 mins)

Learn how to integrate Android camera functionality with Swift image processing. You’ll add photo capture to tasks, implement three image filters in Swift (grayscale, blur, brightness), and understand bidirectional data flow between Kotlin and Swift. This lesson demonstrates working with binary data across the JNI boundary and pixel-level image manipulation.
