Kotlin Multiplatform Libraries

Course details

Kotlin Multiplatform makes it easier to share code across Android, iOS, JVM, web, and backend platforms. In this course, Vladimir Jovanović teaches you how to create and publish a KMP library step by step. Learn how to set up a project, write and test cross-platform code, and handle platform-specific implementations. By the end, you should be ready to publish your library to Maven Central and maintain it effectively.

The course will primarily use Android Studio for project setup and shared code development, while iOS-specific tasks will involve Xcode. This course is perfect for developers looking to adopt Kotlin Multiplatform and streamline their workflows.

Learning objectives
Build a Kotlin Multiplatform library that works for Android, iOS, JVM, and JS.
Configure Gradle to manage dependencies and settings for all targets.
Write platform-specific code and share logic across platforms.
Publish a KMP library to a public repository like Maven Central.
Test a KMP library on multiple platforms to ensure it works as expected.
