Fast Track to Kotlin Native, United Kingdom

We can host this training at your preferred location. Contact us!

Kotlin is a superb choice for JVM development, and now the recommended language for Android. With Kotlin Native you can bring the power and simplicity of Kotlin to platforms where Virtual Machines are not applicable or desirable. Kotlin Native uses LLVM to produce native instructions that execute directly on the target platform e.g. MacOS, ARM and WebAssembly.

In this course you will learn how to use Kotlin alongside native applications and libraries written in C, C++, Objective-C and Swift. You will learn how to generate Kotlin library wrappers using headers from these other languages. With the generated wrappers you will write Kotlin that easily calls into native API’s and makes marshalling data back and forth trivial. You will also learn how to consume Kotlin Native libraries from other environments.

Finally, you will see how this fits into the wider Kotlin ecosystem by creating multi-platform projects that target the JVM, Android, JS and Native platforms.

Delegates must be confident Kotlin developers. Prior exposure to C/C++ terminology and concepts is very helpful but not essential.

Understand where Kotlin Native fits in the ecosystem
Use Kotlin to create native apps, libraries and frameworks
Know which libraries are available on what platforms
Be comfortable consuming C and Objective-C libraries
Have confidence manually managing C data type memory
